CMS

Remarks

The CMS class implements the Cryptographic Message Syntax and allow for various cryptographic operations to be performed on data including:

The class can generate and consume message in a variety of formats including PEM, DER (Binary), and SMIME. The EncryptionAlgorithm and SignatureHashAlgorithm are fully configurable and support a variety of industry standard encryption and hash algorithms.

The class supports additional functionality such as Compression, OAEP, and PSS. The GetRecipientInfo and GetSignerCertInfo methods as well as the RecipientInfo and SignerCertInfo events allow for a dynamic and flexible approach to message processing. Certificate may be loaded ahead of time or as-needed from the events.

Signing Notes

Sign digitally signs the input data with the the specified certificate(s). Certificates are specified by calling AddCertificate or setting the Certificates property.

OutputFormat specifies the encoding of the output message. Valid values are PEM, DER, and SMIME. IncludeCertificates specifies whether the public certificate is included in the signed message. Additional settings allow further configuration. The following properties are applicable when calling this method:

Signature Verification Notes

VerifySignature verifies the signature of the input message.

In order to perform signature verification the public signer's certificate must be present or explicitly specified. In many cases the certificate itself is included in the input message and a certificate does not need to explicitly be set. If a certificate does need to be set for signature verification the certificate may be specified by calling AddRecipientCert or setting RecipientCerts.

When this method is called the SignerCertInfo event fires once for each signature on the message. This event provides details about the signer certificate, as well as the signer certificate itself (if present). The information provided via SignerCertInfo may be used to load an appropriate certificate for verification from within the event. If the CertEncoded parameter of SignerCertInfo is populated the certificate required for verification is already present in the message.

The following property are applicable when calling this method:

If the input message is a detached signature, the original data that was signed must be specified in DetachedSignatureData. In addition the DetachedSignature property must be set to True to instruct the class to treat the input message as a detached signature.

If the input message is compressed EnableCompression must be set to True before calling this method.

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found, the search stops. The order in which the output properties are checked is as follows:

When using streams, you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.

Decryption Notes

Decrypt decrypts the input data with the specified certificate. Certificates are specified by calling AddCertificate or setting the Certificates property.

If the certificate used to encrypt the message is not known ahead of time GetRecipientInfo may be called prior to calling Decrypt to obtain information about the recipient (the entity the for which the message was encrypted). If GetRecipientInfo is called, the RecipientInfo event is fired with information about the recipient which may be used to load an appropriate decryption certificate.

The following properties are applicable when calling this method:

Unicode (Windows)
INT AddCertificate(INT iCertStoreType, LPCWSTR lpszCertStore, LPCWSTR lpszCertStorePassword, LPCWSTR lpszCertSubject);
int ipworksencrypt_cms_addcertificate(void* lpObj, int iCertStoreType, const char* lpszCertStore, const char* lpszCertStorePassword, const char* lpszCertSubject);
int AddCertificate(int iCertStoreType, const QString& qsCertStore, const QString& qsCertStorePassword, const QString& qsCertSubject);

Remarks

This method adds a signing certificate. Signing certificates may be added using this method or by adding a certificate directly to Certificates.

The added certificate(s) will be used to sign the message when Sign is called.

CertStoreType specifies the type of certificate store. The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - 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 (cstMachine)For Windows, this specifies that the certificate store is a machine store.

Note: This store type is not available in Java.

2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates.

Note: This store type is only available in Java.

5 (cstJKSBlob)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 only available in Java.

6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store).

Note: This store type is only available in Java and .NET.

22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format.

Note: This store type is only available in Java and .NET.

23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the and set to the PIN.

Code Example. SSH Authentication with Security Key: certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

CertStore specifies the path to the certificate file. If the CertStoreType is a blob, this specifies the certificate content. See Certificates for details.

CertStorePassword is the password for the certificate (if any).

CertSubject specified the subject of the certificate to load. The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, or E=support@nsoftware.com". Common fields and their meanings are as follows:

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma, it must be quoted.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddRecipientCert Method (CMS Class)

Used to add recipient certificates used to encrypt messages.

Syntax

ANSI (Cross Platform)
int AddRecipientCert(const char* lpCertEncoded, int lenCertEncoded);

Unicode (Windows)
INT AddRecipientCert(LPCSTR lpCertEncoded, INT lenCertEncoded);
int ipworksencrypt_cms_addrecipientcert(void* lpObj, const char* lpCertEncoded, int lenCertEncoded);
int AddRecipientCert(QByteArray qbaCertEncoded);

Remarks

This method adds a public certificate used when Encrypt is called. Public certificates of recipients may be added using this method or by adding a certificate directly to the RecipientCerts property.

CertEncoded must contain the PEM or Base64 encoded public certificate.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (CMS Class)

This method sets or retrieves a configuration setting.

Syntax

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);
char* ipworksencrypt_cms_config(void* lpObj, const char* lpszConfigurationString);
QString Config(const QString& qsConfigurationString);

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

Decrypt Method (CMS Class)

Decrypts the current message.

Syntax

ANSI (Cross Platform)
int Decrypt();

Unicode (Windows)
INT Decrypt();
int ipworksencrypt_cms_decrypt(void* lpObj);
int Decrypt();

Remarks

Decrypt decrypts the input data with the specified certificate. Certificates are specified by calling AddCertificate or setting the Certificates property.

If the certificate used to encrypt the message is not known ahead of time GetRecipientInfo may be called prior to calling Decrypt to obtain information about the recipient (the entity the for which the message was encrypted). If GetRecipientInfo is called, the RecipientInfo event is fired with information about the recipient which may be used to load an appropriate decryption certificate.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

DecryptAndVerifySignature Method (CMS Class)

Decrypts and verifies the signature of the current message.

Syntax

ANSI (Cross Platform)
int DecryptAndVerifySignature();

Unicode (Windows)
INT DecryptAndVerifySignature();
int ipworksencrypt_cms_decryptandverifysignature(void* lpObj);
int DecryptAndVerifySignature();

Remarks

This method decrypts the input data and verifies the signature. Decryption certificates are specified by calling AddCertificate or setting the Certificates property. Certificates used to verify the signature will be taken from the message itself if included, or from the SignerCerts property.

If the certificate used to encrypt the message is not known ahead of time GetRecipientInfo may be called prior to calling Decrypt to obtain information about the recipient (the entity the for which the message was encrypted). If GetRecipientInfo is called, the RecipientInfo event is fired with information about the recipient which may be used to load an appropriate decryption certificate.

In order to perform signature verification the public signer's certificate must be present or explicitly specified. In many cases the certificate itself is included in the input message and a certificate does not need to explicitly be set. If a certificate does need to be set for signature verification the certificate may be specified by calling AddRecipientCert or setting RecipientCerts.

When this method is called the SignerCertInfo event fires once for each signature on the message. This event provides details about the signer certificate, as well as the signer certificate itself (if present). The information provided via SignerCertInfo may be used to load an appropriate certificate for verification from within the event. If the CertEncoded parameter of SignerCertInfo is populated the certificate required for verification is already present in the message.

The following properties are applicable when calling this method:

If the input message is a detached signature, the original data that was signed must be specified in DetachedSignatureData. In addition the DetachedSignature property must be set to True to instruct the class to treat the input message as a detached signature.

If the input message is compressed EnableCompression must be set to True before calling this method.

// Or, subclass CMS and override this emitter function. virtual int FireSignerCertInfo(CMSSignerCertInfoEventParams *e) {...}

Remarks

During verification, this event will be raised while parsing the signer's certificate information. The parameters which are populated depends on the options used when the message was originally signed. This information may be used to select the correct certificate for SignerCerts in order to verify the signature. The following parameters may be populated.

Issuer specifies the subject of the issuer of the certificate used to sign the message.

SerialNumber is the serial number of the certificate used to sign the message.

SubjectKeyIdentifier is the X.509 subjectKeyIdentifier extension value of the certificate used to sign the message encoded as a hex string.

CertEncoded is the PEM (base64 encoded) public certificate needed to verify the signature. Note: when this value is present the class will automatically use this value to perform signature verification.

The SignerCerts property may be set from within this event. In this manner the decision of which signer certificate to load may be delayed until the parameters of this event are inspected and the correct certificate can be located and loaded.

Certificate Type

This is the digital certificate being used.

Parses Encoded as an X509 public key.

Certificate(int iStoreType, const char* lpStore, int lenStore, const char* lpszStorePassword, const char* lpszSubject)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN). The Subject parameter can also take an MD5, SHA1, or SHA256 thumbprint of the certificate to load in a "Thumbprint=value" format.

IPWorksEncryptList Type

Syntax

IPWorksEncryptList<T> (declared in ipworksencrypt.h)

Remarks

IPWorksEncryptList is a generic class that is used to hold a collection of objects of type T, where T is one of the custom types supported by the CMS class.

Methods

GetCount This method returns the current size of the collection.

int GetCount() {}

SetCount This method sets the size of the collection. This method returns 0 if setting the size was successful; or -1 if the collection is ReadOnly. When adding additional objects to a collection call this method to specify the new size. Increasing the size of the collection preserves existing objects in the collection.

int SetCount() {}

Get This method gets the item at the specified position. The index parameter specifies the index of the item in the collection. This method returns NULL if an invalid index is specified.

T* Get(int index) {}

Set This method sets the item at the specified position. The index parameter specifies the index of the item in the collection that is being set. This method returns -1 if an invalid index is specified. Note: Objects created using the new operator must be freed using the delete operator; they will not be automatically freed by the class.

T* Set(int index, T* value) {}

IPWorksEncryptStream Type

Syntax

IPWorksEncryptStream (declared in ipworksencrypt.h)

Remarks

The CMS class includes one or more API members that take a stream object as a parameter. To use such API members, create a concrete class that implements the IPWorksEncryptStream interface and pass the CMS class an instance of that concrete class.

When implementing the IPWorksEncryptStream interface's properties and methods, they must behave as described below. If the concrete class's implementation does not behave as expected, undefined behavior may occur.

Properties

CanRead Whether the stream supports reading.

bool CanRead() { return true; }
CanSeek Whether the stream supports seeking.

bool CanSeek() { return true; }
CanWrite Whether the stream supports writing.

bool CanWrite() { return true; }
Length Gets the length of the stream, in bytes.

int64 GetLength() = 0;

Methods

Close Closes the stream, releasing all resources currently allocated for it.

void Close() {}

This method is called automatically when an IPWorksEncryptStream object is deleted.

Flush Forces all data held by the stream's buffers to be written out to storage.

int Flush() { return 0; }

Must return 0 if flushing is successful; or -1 if an error occurs or the stream is closed. If the stream does not support writing, this method must do nothing and return 0.

Read Reads a sequence of bytes from the stream and advances the current position within the stream by the number of bytes read.

int Read(void* buffer, int count) = 0;

Buffer specifies the buffer to populate with data from the stream. Count specifies the number of bytes that should be read from the stream.

Must return the total number of bytes read into Buffer; this may be less than Count if that many bytes are not currently available, or 0 if the end of the stream has been reached. Must return -1 if an error occurs, if reading is not supported, or if the stream is closed.

Seek Sets the current position within the stream based on a particular point of origin.

int64 Seek(int64 offset, int seekOrigin) = 0;

Offset specifies the offset in the stream to seek to, relative to SeekOrigin. Valid values for SeekOrigin are:

  • 0: Seek from beginning.
  • 1: Seek from current position.
  • 2: Seek from end.

Must return the new position within the stream; or -1 if an error occurs, if seeking is not supported, or if the stream is closed (however, see note below). If -1 is returned, the current position within the stream must remain unchanged.

Note: If the stream is not closed, it must always be possible to call this method with an Offset of 0 and a SeekOrigin of 1 to obtain the current position within the stream, even if seeking is not otherwise supported.

Write Writes a sequence of bytes to the stream and advances the current position within the stream by the number of bytes written.

int Write(const void* buffer, int count) = 0;

Buffer specifies the buffer with data to write to the stream. Count specifies the number of bytes that should be written to the stream.

Must return the total number of bytes written to the stream; this may be less than Count if that many bytes could not be written. Must return -1 if an error occurs, if writing is not supported, or if the stream is closed.

Config Settings (CMS 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.

CMS Config Settings

CompressBeforeSign:   Specifies whether to compress before signing.

When EnableCompression is set to True this property controls whether compression happens before or after signing. If set to True the input data will be compressed before signing. If set to False (default) the input data will be signed and then compressed.

ContentTypeOID:   Specifies the oid for content type.

This setting optionally specifies an OID defining the data content type for the data being processed. This may be set before calling Encrypt, Sign, or SignAndEncrypt.

The default value is 1.2.840.113549.1.7.1 which is the OID for id-data.

CSP:   The Cryptographic Service Provider.

For the Win32 editions, the name of the Cryptographic Service Provider used to provide access to encryption/decryption and signature operations.

NOTE: This config may only be used when the UseCryptoAPI is true.

GenerateSignatureTimestamp:   Whether to generate timestamps in signatures.

If GenerateSignatureTimestamp is True, a timestamp will be generated and added to all signatures created by the class.

The default value is True.

IncludeHeaders:   Tells the class whether to include the headers when encoding the message.

If True (default), the class will include MIME headers when Sign, Encrypt, or SignAndEncrypt are called. If False, only the message will be encoded.

The default value for IncludeHeaders is true.

Note: This setting is only applicable to when OutputFormat is set to SMIME.

IncludeInternalHeaders:   Tells the class whether or not to include the internal headers when encoding the message.

If True, the class will generate and include MIME part headers when Sign, Encrypt, or SignAndEncrypt are called. When VerifySignature, Decrypt, or DecryptAndVerifySignature are called the MIME part headers will be stripped.

When set to False, only the message will be processed, MIME part headers will not be generated or stripped.

The default value for IncludeInternalHeaders is False.

Note: This setting is only applicable to when OutputFormat is set to SMIME.

InputContentTransferEncoding:   Sets the Content-Transfer-Encoding for the signed message.

This setting specifies the Content-Transfer-Encoding header value in signed messages. By default the class will automatically determine the Content-Transfer-Encoding based on the file extension set in InputFile, however this setting may be set to override the determined value or to specify a value if data is read from InputMessage.

If no value is specified and a value cannot be automatically determined the default value 7bit will be used.

Note: This setting is only applicable when OutputFormat is set to SMIME and when calling Sign or SignAndEncrypt and DetachedSignature is True.

InputContentType:   Sets the Content-Type for the signed message.

This setting specifies the Content-Type header value in signed messages. By default the class will automatically determine the Content-Type based on the file extension set in InputFile, however this setting may be set to override the determined value or to specify a value if data is read from InputMessage.

If no value is specified and a value cannot be automatically determined the default value text/plain; charset="iso-8859-1" will be used.

Note: This setting is only applicable when OutputFormat is set to SMIME and when calling Sign or SignAndEncrypt and DetachedSignature is True.

InputMessageHeaders:   Message headers.

This setting specifies the headers of the SMIME message if they are not already present in the input message. In most cases the input message itself will contain the necessary headers, however if the headers are and body of the SMIME message are separate, the headers may be specified in this setting before calling Decrypt, DecryptAndVerifySignature, or VerifySignature.

LogDirectory:   The directory on disk where debug logs are written.

This setting specifies a directory on disk to which debug logs will be written during operation. This should only be set for debugging purposes. Files with various extensions will be written to disk at the location specified with debug data for the operation being performed. If LogFilename is not specified the filenames will be in the format yyyy-MM-dd-HH-mm-ss-fff.

LogFilename:   The base filename to use with LogDirectory.

This setting specifies the base filename to use when LogDirectory is set. If specified the name should be a filename without extension. Various files will be logged with different extensions during operation. This setting defines only the base filename. If unspecified the files will be named with a timestamp in the format yyyy-MM-dd-HH-mm-ss-fff.

LogLevel:   The level of detail for log messages.

This setting specifies the level of detail that is logged via the Log event. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data is logged.
3 (Debug) Debug data is logged.
OAEPMGF1HashAlgorithm:   The MGF1 hash algorithm used with OAEP.

This configuration setting specifies the MGF1 hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"

Note: This setting is not applicable when UseFIPSCompliantAPI is set to true or when the private key of the signing certificate is not exportable since the underlying system implementation does not support separate OAEPRSAHashAlgorithm and OAEPMGF1HashAlgorithm values. In this case the OAEPRSAHashAlgorithm is also used for MGF1.

OAEPParams:   The hex encoded OAEP parameters.

This configuration setting optionally specifies Optimal Asymmetric Encryption Padding (OAEP) parameters to be used when UseOAEP is set to True. The specified value should be hex encoded.

OAEPRSAHashAlgorithm:   The RSA hash algorithm used with OAEP.

This configuration setting specifies that RSA hash algorithm used when UseOAEP is set to True. The default value is SHA256. Possible values are as follows:

  • "SHA1"
  • "SHA224"
  • "SHA256" (default)
  • "SHA384"
  • "SHA512"
  • "RIPEMD160"
  • "MD2"
  • "MD5"
  • "MD5SHA1"
OutputMessageHeaders:   The SMIME headers of the output message.

When IncludeHeaders is set to False the SMIME headers are not included in the output message itself when Sign, Encrypt, or SignAndEncrypt are called. This setting may be used to obtain the SMIME headers separately. This setting is only applicable when OutputFormat is set to SMIME.

RecipientInfoType:   The type of signer information to include in the signed message.

This configuration setting specifies which type of information about the recipient's encryption certificate is included in the encrypted message. Possible values are as follows:

  • 0 (issuerAndSerialNumber - default)
  • 1 (subjectKeyIdentifier)

Note: When subjectKeyIdentifier is selected, the recipient's encryption certificate must contain the subjectKeyIdentifier extension.

SignatureTimestamp:   The signature timestamp in the signed message.

This setting holds the timestamp of the signature. After calling VerifySignature this setting will hold the timestamp identifying when the signature was created. The timestamp is in UTC time with the format yyyyMMddHHmmss. For instance 20181130223821.

SignerInfoType:   The type of signer information to include in the signed message.

This configuration setting specifies which type of information about the signer certificate is included in the signed message. Possible values are as follows:

  • 0 (issuerAndSerialNumber - default)
  • 1 (subjectKeyIdentifier)

Note: When subjectKeyIdentifier is selected, the signing certificate must contain the subjectKeyIdentifier extension.

UseAlgorithmOIDs:   Whether OIDs are used when providing information about the algorithms.

This configuration setting controls whether the EncryptionAlgorithm parameter of the RecipientInfo event is populated with the name of the algorithm, such as 3DES or the corresponding OID such as 1.2.840.113549.3.7.

The default value is False, and the name of the algorithm is used. Set this to True to use the object identifiers instead.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitiveData:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, this class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, Open Secure Sockets Layer (OpenSSL) support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.

Trappable Errors (CMS Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
