Office365Backup Class
Properties Methods Events Config Settings Errors
The Office365Backup class provides an easy way to store messages from Office365.
Syntax
cloudbackup.Office365Backup
Remarks
This class provides a simple way to backup messages from Office365 to disk. Messages are stored in standard .eml (RFC 822) format which can be opened by any mail program including Outlook, Thunderbird, Apple Mail, and more. All communication takes place using the Microsoft Graph API v1.0.
To use the class first authenticate to the service by configuring the OAuth property and calling the Authorize method. Next, set the DataFolder property to a local path and call the StartBackup method. Messages will be grouped by month and stored in subfolders of DataFolder. For instance, all messages from October 2023 would be stored in the folder 2023-10.
The following sections describe the behavior and configuration options for the class in more detail.
Authentication
This class requires authentication via OAuth 2.0. This can be performed by using the classs OAuth settings. After configuring the OAuth settings appropriately, calling Authorize will retrieve the required access token used to access the relevant protected resources. This token will be used automatically by the class in subsequent requests. Please see the following for a simple example:
component.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication;
component.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode;
component.OAuth.ClientId = CLIENT_ID;
component.OAuth.ClientSecret = CLIENT_SECRET;
component.Authorize();
The class will request a refresh token during authorization by default. The refresh token allows the class to automatically obtain a new access token if the current access token is about to expire. Whether to automatically obtain a new access token is controlled by the OAuthAutomaticRefresh setting and is true by default.
For an in-depth look at various configurations of the OAuth settings, please see the OAuth property description. Additionally, it is possible to perform OAuth authentication using a separate process. For more details, please see the Authorization property description.
Starting the Backup
Before calling StartBackup, set the DataFolder property to a path on disk where the class will save all messages. Within this folder, messages will be saved to a subfolder with the year and month the message was created. For example, all messages from October 2023 would be stored in the folder \DataFolder\2023-10\.
DataFolder may be set to the location of a previous backup. During the backup, the class will only retrieve messages that have not already been backed up.
After setting DataFolder, the Filter, StartDate, and EndDate properties can be set to select a subset of messages for backup. These properties will be utilized when retrieving a list of message IDs during the Initialization Phase.
Additionally, the MaxConnections property can be set to control the number of simultaneous connections used during the process. Generally, more connections yield better performance, but excessive connections can impair performance. Please see the property description for further details.
Lastly, call StartBackup to begin the backup process. Note that this method is non-blocking, and will return before the backup completes. For example:
bool backupComplete = false;
component.OnEndBackup += (o, e) => {
backupComplete = true;
};
// Assuming successful authentication
component.Authorize();
component.DataFolder = "C:\\BackupDirectory\\";
component.StartDate = "2023/07/01"; // Only backup messages created after July 01, 2023
component.EndDate = "2023/07/31"; // Only backup messages created before July 31, 2023
component.MaxConnections = 5; // 5 simultaneous connections
component.StartBackup();
while (!backupComplete) {
component.DoEvents();
}
At any point during the backup, the AbortBackup method can be called to stop the backup process. Once the backup is complete, the EndBackup event will fire. The following events may fire during the backup and provide information about the progress of the backup:
The backup process is separated into the phases listed below.
Phase | Description |
Initialization Phase | The class will authenticate to the server and obtain a list of messages to be considered for backup. |
Backup Phase | The class retrieves the content of each message that will be backed up. Messages that have been previously backed up will be automatically skipped by default. |
Sync Phase | If SyncDeletes is true any messages that have been deleted remotely will be deleted locally. The default value of SyncDeletes is false and no messages will be deleted locally. |
The sections below provide a detailed description of each phase.
Initialization Phase
After calling StartBackup the class will first retrieve a list of all message IDs to backup. This operation is performed before saving any messages on disk.
Note that multiple requests may be made in this phase as results from the server may be paged. This process may take some time depending on the number of messages to be backed up.
Information regarding this process and the number of retrieved message IDs will be available in the Log event. Once this phase is completed, the MessageCount property will contain the total number of messages the class will attempt to back up.
Backup Phase
Once all message IDs have been retrieved, the class will start the Backup Phase. During this phase, the class will fetch and save the message content for each message ID retrieved during the Initialization Phase. Assuming no errors are encountered during the process, for each message the BeforeMessageBackup, MessageBackup, and AfterMessageBackup events will fire in that order. Please see a description and possible applications of each event below.
Event | Description |
BeforeMessageBackup | This event will fire before the class fetches the content of each message.
Before the message's content is fetched, this event can be used to:
|
MessageBackup | This event will fire after a message's content is retrieved successfully and indicates the message is about to be saved locally.
Before the message is saved locally, this event can be used to:
|
AfterMessageBackup | This event will fire after the message is saved locally and indicates the message was successfully backed up.
If this event does not fire for a specific message, it could mean:
|
If an error is encountered for any reason during the Backup Phase, the MessageError event will fire, containing information related to the error itself. By default, the class will attempt to retry the operation MaxRetryCount times, and subsequent requests will be made every RetryInterval seconds assuming an error continues to occur.
For more control over the retry logic in the event of a message error, the MessageError event can be handled accordingly. Please see the event description for more details.
Once the Backup Phase is finished, the optional Sync Phase may begin if SyncDeletes is set to True. Otherwise, the backup process will be complete, and EndBackup will fire accordingly.
If DataFolder points to an existing backup, the class will first check to see if the message is present locally before retrieving the message.
If the message is already present, the class will compare the last modified date of the local and remote messages. If the last modified date differs between the two locations, the local message content will be updated. Otherwise, the class will skip backing up this message. Note the mentioned behavior can be observed and/or overridden within the BeforeMessageBackup event.
Sync Phase
Once the Backup Phase is complete, the optional Sync Phase may begin. By default, this phase will not occur but can be enabled by setting the SyncDeletes property to True.
During this phase, the class will check every message in the local backup to determine if it has been deleted remotely. If the class finds that a message no longer exists remotely, MessageDelete will fire, and the message will be removed locally. For example:
bool backupComplete = false;
component.OnEndBackup += (o, e) => {
backupComplete = true;
};
component.OnMessageDelete += (o, e) => {
Console.WriteLine("Message does not exist remotely: " + e.Id);
Console.WriteLine("Deleting local file: " + e.BackupFile);
};
component.SyncDeletes = true;
component.DataFolder = "C:\\BackupDirectory\\";
component.StartBackup();
while (!backupComplete) {
component.DoEvents();
}
Once this phase is finished, EndBackup will fire, indicating the backup process is complete.
Ending the Backup
Once all phases are complete, the EndBackup event will fire, indicating the backup is complete. At any point during the backup process, AbortBackup can be called, terminating the ongoing process. In this case, the existing local backup state will be preserved up until the point this method was called, and EndBackup will fire as expected.
For a detailed example of the complete process, please see below:
bool backupComplete = false;
int messagesBackedUp = 0;
component.OnEndBackup += (o, e) => {
backupComplete = true;
};
component.OnBeforeMessageBackup += (o, e) => {
if (e.Skip) {
e.Skip = false; // Force message to be backed up
}
};
component.OnAfterMessageBackup += (o, e) => {
messagesBackedUp++;
};
component.OnMessageError += (o, e) => {
if (e.Retry) {
Console.WriteLine("Error backing up message, retrying: " + e.ErrorCode + ": " + e.ErrorMessage);
} else {
Console.WriteLine("Error backing up message, skipping: " + e.ErrorCode + ": " + e.ErrorMessage);
}
};
component.onMessageDelete += (o, e) => {
Console.WriteLine("Message does not exist remotely: " + e.Id);
Console.WriteLine("Deleting local file: " + e.BackupFile);
};
component.MaxConnections = 10;
component.DataFolder = "C:\\BackupDirectory\\";
component.StartDate = "2023/07/01";
component.EndDate = "2023/07/31";
component.SyncDeletes = true;
component.StartBackup();
while (!backupComplete) {
component.DoEvents();
}
Console.WriteLine("Backup Complete!");
Console.WriteLine("Messages retrieved: " + messagesBackedUp);
Console.WriteLine("Messages skipped: " + component.MessageCount - messagesBackedUp);

Authorization Property (Office365Backup Class)
An OAuth Authorization String.
Syntax
public String getAuthorization(); public void setAuthorization(String authorization);
Default Value
""
Remarks
This property is used to specify an OAuth authorization string. Setting it is a requirement for using the component.
For complex profiles or grant types, or for more control of the flow, it is possible to perform OAuth authentication using a separate process. Once complete you should have an authorization string which looks like:
Bearer ACCESS_TOKEN_VALUE
Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the class to ignore the values set in the OAuth property.
Alternatively, the OAuth property can be used to set the internal OAuth settings, and the Authorize method can be called to retrieve the authorization string. Please see relevant property and method descriptions for more details.
This property is not available at design time.
DataFolder Property (Office365Backup Class)
Specifies the parent folder where fetched messages will be saved.
Syntax
public String getDataFolder(); public void setDataFolder(String dataFolder);
Default Value
""
Remarks
This property specifies the parent folder where all fetched messages will be saved. Within this folder, messages will be saved to a subfolder associated with the year and month the message was created remotely. For example: \DataFolder\2023-07\
Additionally, after the backup has started, a lock file will be generated and saved here, within the \.meta\ subfolder. This lock serves as an indicator that the current backup process is currently in progress, and will be deleted once the backup has stopped.
Please note that all fetched messages will be saved with the file extension EML (*.eml). The filename will be the hex-encoded SHA-1 hash of a messages unique ID with the EML extension. For example: /DataFolder/2023-09/6444...57d2.eml
Important message info will be written to each file, such as the unique ID and the last modified time of the message. This info will be stored within the custom header X-NS-Backup.
EndDate Property (Office365Backup Class)
Specifies the upper limit of a date range to be used when fetching messages.
Syntax
public String getEndDate(); public void setEndDate(String endDate);
Default Value
""
Remarks
This property is used to specify the upper limit of a date range to be used when fetching messages.
When set, the class will only attempt to fetch messages that were created on or before the specified date. No messages created after this date will be backed up. By default, this value is empty, and no upper limit will be applied to the date range when fetching messages. This property must have the following format: yyyy/MM/dd
This property can be set alongside StartDate to only fetch messages between two distinct dates. For example, to fetch messages created within the month of July 2023, StartDate can be set to 2023/07/01, and EndDate can be set to 2023/07/31.
Filter Property (Office365Backup Class)
Specifies the filter to be applied to requests during the Initialization Phase.
Syntax
public String getFilter(); public void setFilter(String filter);
Default Value
""
Remarks
This property specifies the filter to be applied to requests made during the Initialization Phase. Only messages matching this filter will be returned for processing in the Backup Phase.
This property follows the OData protocol syntax.
Example (Backup Messages from a Specific Folder)
office365backup.Filter = "parentFolderId eq 'Inbox'";
Example (Backup Messages from a Specific Address)
office365backup.Filter = "address eq 'specific@address.com'";
Example (Backup Messages from a Specific Folder and Address)
office365backup.Filter = "parentFolderId eq 'Inbox' and address eq 'specific@address.com'";
More information regarding proper syntax and additional filter options can be found here: https://learn.microsoft.com/en-us/graph/filter-query-parameter?tabs=http
Firewall Property (Office365Backup Class)
A set of properties related to firewall access.
Syntax
public Firewall getFirewall(); public void setFirewall(Firewall firewall);
Remarks
This is a Firewall-type property, which contains fields describing the firewall through which the class will attempt to connect.
Please refer to the Firewall type for a complete list of fields.MaxConnections Property (Office365Backup Class)
Specifies the maximum number of simultaneous connections the class will use during the backup process.
Syntax
public int getMaxConnections(); public void setMaxConnections(int maxConnections);
Default Value
5
Remarks
This property specifies the maximum number of simultaneous connections the class will use during the backup process. By default this property is set to 5 maximum connections. Increasing this value can improve backup performance to an extent.
While there is no predefined limit on the specified number of connections, please use caution when increasing the value of this property. With more simultaneous connections, the rate at which the class sends requests will typically increase. In this case, it is possible that a high request frequency causes the service to refuse subsequent requests due to the quota limit being reached.
While the exact limits may differ from service to service, it's important to note that increasing this value may not always improve backup performance. Please check with the associated service for further details regarding quota limits.
MessageCount Property (Office365Backup Class)
Contains the total number of messages the class will back up.
Syntax
public int getMessageCount();
Default Value
0
Remarks
This property contains the total number of messages that the class will back up. After calling StartBackup, the class will begin the Initialization Phase, and will attempt to retrieve a list of all message IDs to backup.
Once the Initialization Phase is complete, this property will remain constant and contain the total number of messages the class will back up. Information regarding the number of retrieved message IDs will be available in the Log event.
This property is read-only and not available at design time.
OAuth Property (Office365Backup Class)
This property holds the OAuth Settings.
Syntax
public OAuthSettings getOAuth();
Remarks
This property is used to define the necessary fields to authentication with the service provider. The class will have the following OAuth settings by default:
Authorization Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/authorize" |
Token Server URL | "https://login.microsoftonline.com/common/oauth2/v2.0/token" |
Scopes | "mail.read" |
Additionally, depending on how the application is registered (Ex. Multi-tenant) and what GrantType is selected (Ex. Client Credentials and Password), it may be required to use the tenant ID rather than "common" in the ServerAuthURL and ServerTokenURL fields. In the case of Client Credentials and Password grant types, it is also required to use the "default" scopes of the app registration. See below for examples of the modified URLs and scopes:
Authorization Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/authorize" |
Token Server URL | "https://login.microsoftonline.com/{TENANT_ID}/oauth2/v2.0/token" |
Scopes | "https://graph.microsoft.com/.default" |
Below is a brief description of the different ClientProfile and GrantType values that are supported by this class. For a more in-depth description of what needs to be set, refer to the service documentation.
Application Profile
This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the class. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.
To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the AccessToken field will be populated. Additionally, if a refresh token was provided the RefreshToken field will be populated as well. These values of the fields are for informational purposes. The class will also cache these tokens along with when the AccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the class will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new AccessToken. If the Authorize method was not used and user interaction would be required, the class will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the GrantType field. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.
A brief description of the supported values for the GrantType field are below. For more information, see the service documentation.
Authorization Code
When using the Authorization Code grant type, the class will use an authorization code to get an access token. For this GrantType the class expects a ClientId, ClientSecret, ServerAuthURL, and ServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the authorization code, setting the AuthorizationCode field, from the redirect. Immediately, the class will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the RefreshToken field is set, or a refresh token is cached, then the class will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.
Example:
office365backup.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication;
office365backup.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode;
office365backup.OAuth.ClientId = CLIENT_ID;
office365backup.OAuth.ClientSecret = CLIENT_SECRET;
office365backup.Authorize();
Implicit
Note: This grant type is considered insecure and should only be used when necessary.
When using the Implicit grant type, the class will request the authorization server to get an access token. For this GrantType the class expects a ClientId, ClientSecret, and ServerAuthURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the access token from the redirect.
A disadvantage of the grant type is that can not use a refresh token to silently get a new access token. Most service providers offer a way to silently get a new access token. See the service documentation for specifics. This means the class will not be able to automatically get a fresh token once it expires.
Password
Note: This grant type is considered insecure and should only be used when necessary.
When using the Resource Owner Password Credentials grant type, the class will authenticate as the resource owner. This allows for the class to avoid user interaction. This grant type often has specific limitations put on it by the service provider. See the service documentation for more details.
For this GrantType the class requires OAuthPasswordGrantUsername, ClientSecret, and ServerTokenURL to be set. The ClientSecret should be set to the password of the account instead of a typical secret. In some cases, the ClientId also needs to be set. When the Authorize method is called, the component will make a request to the token server for an access token using the username and password. The token server will return an access token if the authentication was successful. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.
Web Profile
This profile is similar to setting the class to the Application profile and Authorization Code grant type except the class will not launch the browser. It is typically used in situations where there is a back-end that is supporting some front end. This profile expects that ClientId, ClientSecret, ServerAuthURL, ServerTokenURL, and the ReturnURL fields to be set. Before calling the Authorize method, the WebAuthURL field should be queried to get a URL. This URL should be used to redirect the user to the authorization page for the service provider. The redirect_uri parameter of this URL is mapped to the ReturnURL field. The ReturnURL field should be set to some web server that will parse the authorization code out of the query parameter from the redirect. Once the authorization code is parsed, it should be passed back to the server where it is then set to the AuthorizationCode field. Once that is set, the Authorize method can be called to exchange the authorization code for an access token and refresh token if provided. The class will then cache these values like normal and use them to make requests. If the RefreshToken field is set, or a refresh token is cached, then the Authorize method can immediately be called to make a request to the token server to get a new access token.Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.
This property is read-only and not available at design time.
Please refer to the OAuthSettings type for a complete list of fields.Proxy Property (Office365Backup Class)
A set of properties related to proxy access.
Syntax
public Proxy getProxy(); public void setProxy(Proxy proxy);
Remarks
This property contains fields describing the proxy through which the class will attempt to connect.
Please refer to the Proxy type for a complete list of fields.SSLAcceptServerCert Property (Office365Backup Class)
Instructs the class to unconditionally accept the server certificate that matches the supplied certificate.
Syntax
public Certificate getSSLAcceptServerCert(); public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);
Remarks
If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.
You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.
Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.
Please refer to the Certificate type for a complete list of fields.SSLCert Property (Office365Backup Class)
The certificate to be used during Secure Sockets Layer (SSL) negotiation.
Syntax
public Certificate getSSLCert(); public void setSSLCert(Certificate SSLCert);
Remarks
This property includes the digital certificate that the class will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.
Please refer to the Certificate type for a complete list of fields.SSLProvider Property (Office365Backup Class)
The Secure Sockets Layer/Transport Layer Security (SSL/TLS) implementation to use.
Syntax
public int getSSLProvider(); public void setSSLProvider(int SSLProvider); Enumerated values: public final static int sslpAutomatic = 0; public final static int sslpPlatform = 1; public final static int sslpInternal = 2;
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic), the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are as follows:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |
1 (sslpPlatform) | Uses the platform/system implementation. |
2 (sslpInternal) | Uses the internal implementation. |
In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.
When Automatic is selected, the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols, the internal implementation is used.
SSLServerCert Property (Office365Backup Class)
The server certificate for the last established connection.
Syntax
public Certificate getSSLServerCert();
Remarks
This property contains the server certificate for the last established connection.
SSLServerCert is reset every time a new connection is attempted.
This property is read-only.
Please refer to the Certificate type for a complete list of fields.StartDate Property (Office365Backup Class)
Specifies the lower limit of a date range to be used when fetching messages.
Syntax
public String getStartDate(); public void setStartDate(String startDate);
Default Value
""
Remarks
This property is used to specify the lower limit of a date range to be used when fetching messages.
When set, the class will only attempt to fetch messages that were created on or after the specified date. No messages created before this date will be backed up. By default, this value is empty, and no lower limit will be applied to the date range when fetching messages. This property must have the following format: yyyy/MM/dd
This property can be set alongside EndDate to only fetch messages between two distinct dates. For example, to fetch messages created within the month of July 2023, StartDate can be set to 2023/07/01, and EndDate can be set to 2023/07/31.
SyncDeletes Property (Office365Backup Class)
Specifies whether the Sync Phase will occur.
Syntax
public boolean isSyncDeletes(); public void setSyncDeletes(boolean syncDeletes);
Default Value
False
Remarks
This property specifies whether the Sync Phase will occur. By default, this property is False, and the Sync Phase will be disabled.
If set to True, the Sync Phase will be enabled. During this phase, the class will check for the remote existence of every message in the local backup state. If the class finds that a message no longer exists remotely, MessageDelete will fire, and the message will be removed locally.
Note, if enabled, the Sync Phase will occur after the Backup Phase is finished. Once the Sync Phase is finished, EndBackup will fire.
AbortBackup Method (Office365Backup Class)
Used to abort an ongoing backup process.
Syntax
public void abortBackup();
Remarks
This method is used to abort an ongoing backup process. This can be called any time during the backup and will force the process to end. Afterwards, the EndBackup event will fire.
Authorize Method (Office365Backup Class)
Get the authorization string required to access the protected resource.
Syntax
public void authorize();
Remarks
This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the ClientProfile field and the GrantType field. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth property.
For more information, see the OAuth property.
Config Method (Office365Backup Class)
Sets or retrieves a configuration setting.
Syntax
public String config(String configurationString);
Remarks
Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
DoEvents Method (Office365Backup Class)
This method processes events from the internal message queue.
Syntax
public void doEvents();
Remarks
When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.
ResumeBackup Method (Office365Backup Class)
Used to resume a previously aborted or incomplete backup process.
Syntax
public void resumeBackup();
Remarks
This method can be used to resume a previously aborted or incomplete backup process. When called, the class will begin the Initialization Phase as expected, but the behavior will differ during the Backup Phase. For further information, please see the BeforeMessageBackup event description.
StartBackup Method (Office365Backup Class)
Used to start a backup process.
Syntax
public void startBackup();
Remarks
This method is used to start a backup process. This method is non-blocking and will return immediately.
Before calling this method, the DataFolder must be set to a valid local directory, as all messages will be saved here. After specifying this, StartBackup can be called.
Users can optionally set the Filter, StartDate, and EndDate properties to support applying various conditions on which messages will be backed up. Additionally, to improve the performance of the backup, MaxConnections can be set to use more simultaneous connections during the process. For example:
backup.DataFolder = "C:\\BackupDirectory\\";
backup.StartDate = "2023/07/01";
backup.EndDate = "2023/07/31";
backup.Filter = "parentFolderId eq 'Inbox'";
backup.MaxConnections = 5;
backup.StartBackup();
Note that DataFolder can be set to a location on disk where a backup was previously performed. In this case, the backup will be performed against the current local state, and the behavior during the Backup Phase will differ from usual. For further information, please see the BeforeMessageBackup event description.
AfterMessageBackup Event (Office365Backup Class)
This event is fired after a message has successfully been backed up.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void afterMessageBackup(Office365BackupAfterMessageBackupEvent e) {} ... } public class Office365BackupAfterMessageBackupEvent { public String id; }
Remarks
This event will fire for each message that is successfully backed up.
The Id parameter represents the unique identifier of this message.
BeforeMessageBackup Event (Office365Backup Class)
This event is fired before the content of a message is fetched.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void beforeMessageBackup(Office365BackupBeforeMessageBackupEvent e) {} ... } public class Office365BackupBeforeMessageBackupEvent { public String id; public String subject; public String from; public String sentTo; public String cc; public String bcc; public String receivedDateTime; public String sentDateTime; public String createdDateTime; public String bodyContentType; public boolean hasAttachments; public String backupFile; //read-write public boolean skip; //read-write }
Remarks
This event fires before the content of each message is fetched. Various message properties will be reported before the raw message content is retrieved.
The BackupFile parameter contains the full path and filename this message will be saved to locally. By default, this parameter will be a combination of the DataFolder, the year and month the message was created, and the message-specific filename. The filename will be the hex-encoded SHA-1 hash of the Id parameter with the EML extension. For example: /DataFolder/2023-09/6444...57d2.eml
The BackupFile parameter can be modified to change both the path and filename the message will be saved to locally.
The Skip parameter determines whether the message will be skipped. This will typically be False by default, but can be set to True in order to skip backing up this message.
If the backup is performed against an existing local state, it is possible the relevant remote message exists locally. If the message exists locally, the class will compare the last modified date of the local and remote messages. In the case that the last modified dates are equal, the Skip parameter will be True and the class will skip backing up this message. Note to force the class to back up a message in all scenarios, this parameter can be set to False.
The Id parameter specifies the unique identifier of this message.
EndBackup Event (Office365Backup Class)
This event is fired after the backup process is complete.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void endBackup(Office365BackupEndBackupEvent e) {} ... } public class Office365BackupEndBackupEvent { }
Remarks
This event will fire after the backup process has completed. Note when this fires, it is not guaranteed that each message was successfully backed up. This event only signifies that every retrieved message has been processed, indicating the message was either successfully downloaded or skipped.
Error Event (Office365Backup Class)
Fired when information is available about errors during data delivery.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void error(Office365BackupErrorEvent e) {} ... } public class Office365BackupErrorEvent { public int errorCode; public String description; }

0 (Error) | Error events are logged. |
1 (Info - Default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are logged. |
The value 0 (Error) logs basic error information encountered during the backup process.
The value 1 (Info) logs basic information regarding the backup, as well as status details regarding HTTP requests and responses.
The value 2 (Verbose) logs additional information regarding HTTP requests and responses.
The value 3 (Debug) logs all headers and message content for both HTTP requests and responses, as well as additional debug information related to the backup process.
Message contains the log message.
LogType identifies the type of log entry. Possible values are as follows:
- Error
- Info
- Verbose
- Debug
- RequestHeaders
- ResponseHeaders
- RequestBody
- ResponseBody
- ProxyRequest
- ProxyResponse
- FirewallRequest
- FirewallResponse
MessageBackup Event (Office365Backup Class)
This event is fired before each message is saved locally.

Remarks
This event fires before each message is saved locally after retrieving the message content.
The Skip parameter determines whether the message will be skipped. This will be False by default, but can be set to True in order to skip backing up this message.
The Id parameter specifies the unique identifier of this message.
The Eml parameter contains the RFC822-encoded text of this message.
MessageDelete Event (Office365Backup Class)
This event fires before a message is deleted from the local backup.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void messageDelete(Office365BackupMessageDeleteEvent e) {} ... } public class Office365BackupMessageDeleteEvent { public String id; public String backupFile; public boolean skip; //read-write }
Remarks
This event will fire before a message is deleted from the local backup. Note that this event is only applicable when SyncDeletes is set to True and the locally backed up message does not exist remotely.
The Id parameter represents the unique identifier of this message.
The BackupFile parameter specifies the filename of the existing backup file that will be deleted.
The Skip parameter determines whether the message will be skipped. By default, this will be false, and the message will be deleted. This can be manually set to true to override this behavior.
MessageError Event (Office365Backup Class)
This event fires each time an error is encountered when backing up a message.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void messageError(Office365BackupMessageErrorEvent e) {} ... } public class Office365BackupMessageErrorEvent { public String id; public int errorCode; public String errorMessage; public boolean retry; //read-write }
Remarks
This event will fire each time there is an error encountered when backing up a message. Errors can arise when attempting to fetch various message information and content or while attempting to save the message to disk during the backup process.
The Id parameter represents the unique identifier of this message.
The ErrorCode parameter indicates the messages error code.
The ErrorMessage parameter indicates the description associated with the specified error.
The Retry parameter specifies whether the class will attempt to backup this message once more. If True, the class will attempt to backup this message again. If False, the class will skip backing up this message, and the message will be skipped.
By default, the class will reattempt this message backup MaxRetryCount times (Default - 5 reattempts). This event will fire with Retry as true when this is the case. After MaxRetryCount failed backup attempts, this event will fire with Retry as false. The Retry parameter can be set manually to force the class to retry, or not. Each reattempt when a message error occurs will be separated by RetryInterval seconds (Default - 3 seconds).
SSLServerAuthentication Event (Office365Backup Class)
Fired after the server presents its certificate to the client.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void SSLServerAuthentication(Office365BackupSSLServerAuthenticationEvent e) {} ... } public class Office365BackupSSLServerAuthenticationEvent { public byte[] certEncoded; public String certSubject; public String certIssuer; public String status; public boolean accept; //read-write }
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (Office365Backup Class)
Fired when secure connection progress messages are available.
Syntax
public class DefaultOffice365BackupEventListener implements Office365BackupEventListener { ... public void SSLStatus(Office365BackupSSLStatusEvent e) {} ... } public class Office365BackupSSLStatusEvent { public String message; }
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

Config Settings (Office365Backup Class)
The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.Office365Backup Config Settings
When True, the class will first check if the AuthorizationScope field contains the offline_access scope. If the mentioned scope is not present, the class will add the scope to the field. Otherwise, nothing will occur.
Note: When False, this configuration will have no effect and the scopes specified in AuthorizationScope will not be modified. In this case, it is possible that a refresh token is retrieved if the offline_access scope is manually specified.
- 0 (None - Idle)
- 1 (Initialization Phase)
- 2 (Backup Phase)
- 3 (Syncing Phase)
OAuth Config Settings
Bearer (default) | When the access token returned by the server is a Bearer type, the authorization string returned by Authorize will be in the format "Bearer access_token". This can be supplied as the value of the HTTP Authorization header. |
For example, when using the Authorization Code grant type, the RefreshToken field should be set to a valid refresh token. When using the Client Credential grant type however, the class does not need any additional properties set as it can already get a new access token without user interaction.
If set to true (default) the redirect_uri will be sent in all cases. If set to false the redirect_uri will only be sent if it has a value.
To parse the payload for specific claims, see OAuthJWTXPath.

Gmail gmail = new Gmail();
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
Console.WriteLine(gmail.Config("OAuthTransferredRequest"));
C++
Gmail gmail;
gmail.Config("OAuthTransferredRequest=on");
gmail.Authorize();
printf("%s\r\n", gmail.Config("OAuthTransferredRequest"));
This setting can also be set to activate or deactivate the web server. Under normal circumstances, this would not be required as the class will automatically start and stop the web server when Authorize is called. In certain cases, it is required to start the webserver before calling Authorize. For example, if the ReturnURL needs to be set to a relay server, then you will need to start the web server manually. Another example would be when the OAuthReUseWebServer is set to true, the server will not be automatically stopped, and this configuration setting must be set to "false" to stop the embedded web server.
The OAuthWebServerCertStoreType field specifies the type of the certificate store specified by OAuthWebServerCertStore. If the store is password protected, specify the password in OAuthWebServerCertStorePassword.
OAuthWebServerCertStore is used in conjunction with the OAuthWebServerCertSubject field in order to specify the certificate to be used during SSL.
Designations of certificate stores are platform dependent.
The following designations are the most common User and Machine certificate stores in Windows:
MY | A certificate store holding personal certificates with their associated private keys. |
CA | Certifying authority certificates. |
ROOT | Root certificates. |
In Java, the certificate store normally is a file containing certificates and optional private keys.
When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).
Note: This is required when OAuthWebServerSSLEnabled is set to true.
Note: This is only applicable when OAuthWebServerSSLEnabled is set to true.
0 | User - This is the default for Windows. This specifies that the certificate store is a certificate store owned by the current user. Note: This store type is not available in Java. |
1 | Machine - For Windows, this specifies that the certificate store is a machine store. Note: This store type is not available in Java. |
2 | PFXFile - The certificate store is the name of a PFX (PKCS12) file containing certificates. |
3 | PFXBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS12) format. |
4 | JKSFile - The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: This store type is available only in Java. |
5 | JKSBlob - The certificate store is a string (binary or Base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: This store type is available only in Java. |
6 | PEMKeyFile - The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. |
7 | PEMKeyBlob - The certificate store is a string (binary or Base64-encoded) that contains a private key and an optional certificate. |
14 | PPKFile - The certificate store is the name of a file that contains a PPK (PuTTY Private Key). |
15 | PPKBlob - The certificate store is a string (binary) that contains a PPK (PuTTY Private Key). |
16 | XMLFile - The certificate store is the name of a file that contains a certificate in XML format. |
17 | XMLBlob - The certificate store is a string that contains a certificate in XML format. |
The special value "*" picks a random certificate in the certificate store.
The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:
Field | Meaning |
CN | Common Name. This is commonly a hostname like www.server.com. |
O | Organization |
OU | Organizational Unit |
L | Locality |
S | State |
C | Country |
E | Email Address |
If a field value contains a comma, it must be quoted.
Note: This is required when OAuthWebServerSSLEnabled is set to true.
The default value is localhost.
HTTP Config Settings
When True, the class adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".
The default value is True.
If set to True (default), the class will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the class throws an exception if the server does not support HTTP/2.
The default value is True.
This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.
The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".
The default value is False.
If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the class throws an exception.
Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.
A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).
The default value is 0 (Never). In this case, redirects are never followed, and the class throws an exception instead.
Following are the valid options:
- 0 - Never
- 1 - Always
- 2 - Same Scheme
- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"
When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.
HTTP/2 Notes
When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.
If the server does not support HTTP/2, the class will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.
HTTP/2 is supported on all platforms. The class will use the internal security implementation in all cases when connecting.
HTTP/3 Notes
HTTP/3 is supported only in .NET and Java.
When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.
The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:
Sat, 29 Oct 2017 19:43:31 GMT.
The default value for KeepAlive is false.
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are logged. |
The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.
The value 2 (Verbose) logs additional information about the request and response.
The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
To save all items to the collection, set this configuration setting to -1. If no items are wanted, set this to 0, which will not save any items to the collection. The default for this configuration setting is -1, so all items will be included in the collection.
The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .
Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.
This configuration setting is useful for extending the functionality of the class beyond what is provided.
.NET
Http http = new Http();
http.Config("TransferredRequest=on");
http.PostData = "body";
http.Post("http://someserver.com");
Console.WriteLine(http.Config("TransferredRequest"));
C++
HTTP http;
http.Config("TransferredRequest=on");
http.SetPostData("body", 5);
http.Post("http://someserver.com");
printf("%s\r\n", http.Config("TransferredRequest"));
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.
The default value is False and the hostname will always be used exactly as specified.
When True (default), the class will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.
Override the default with the name and version of your software.
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
If this entry is set, the class acts as a server. RemoteHost and RemotePort are used to tell the SOCKS firewall in which address and port to listen to. The firewall rules may ignore RemoteHost, and it is recommended that RemoteHost be set to empty string in this case.
RemotePort is the port in which the firewall will listen to. If set to 0, the firewall will select a random port. The binding (address and port) is provided through the ConnectionStatus event.
The connection to the firewall is made by calling the Connect method.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.
0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This setting is provided for use by classs that do not directly expose Firewall properties.
Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.
If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

By default, this configuration setting is set to False.
0 | IPv4 only |

2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this configuration setting has no effect if SSLProvider is set to Platform.
If set to True, the class will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the class is the same.

When set to 0 (default), the CRL check will not be performed by the class. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
When set to 0 (default), the class will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the class will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Note: This value must be set after SSLProvider is set.
Example values:
obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=SSL_RSA_WITH_RC4_128_SHA");

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the class will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider), please be aware of the following notes:
- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the class when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
Note: When SSLProvider is set to Internal this value is automatically set to true. This is needed for proper validation when using the internal provider.
When set, the class will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the class will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipherStrength[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipherSuite[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedKeyExchange[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedKeyExchangeStrength[connId]");
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedVersion[connId]");
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ... Root Cert... d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the class will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the class throws an exception.
The format of this value is a comma-separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
