Possible values are:
| 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, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

{"healthyRetryPolicy": {"minDelayTarget": 1, "maxDelayTarget": 5, "numRetries": 5, "numMaxDelayRetries": 5, "backoffFunction": "linear"}}
set_topic_attributes Method
Sets attributes on the specified topic.
Syntax
def set_topic_attributes(topic_arn: str, attribute_type: int, attribute_value: str) -> None: ...
Remarks
This method may be used to specify attributes on the specified topic.
TopicArn specifies the topic.
AttributeType determines which attribute is set and AttributeValue specifies the value. The following table provides more information:
| AttributeType | AttributeValue |
| 0 (DisplayName) | A human readable name to be used in the "From" field for email based endpoints |
| 1 (AccessPolicy) | A JSON serialized access policy for the topic |
| 2 (DeliveryPolicy) | A JSON serialized delivery policy for the topic |
An example access policy is:
{"Version":"2008-10-17","Id":"__default_policy_ID","Statement":[{"Sid":"__default_statement_ID","Effect":"Allow","Principal":{"AWS":"*"},"Action":["SNS:Publish","SNS:RemovePermission","SNS:SetTopicAttributes","SNS:DeleteTopic","SNS:ListSubscriptionsByTopic","SNS:GetTopicAttributes","SNS:Receive","SNS:AddPermission","SNS:Subscribe"],"Resource":"arn:aws:sns:us-east-1:120151960619:TestTopic","Condition":{"StringEquals":{"AWS:SourceOwner":"120151960619"}}},{"Sid":"__console_pub_0","Effect":"Allow","Principal":{"AWS":"*"},"Action":"SNS:Publish","Resource":"arn:aws:sns:us-east-1:120151960619:TestTopic"}]}
An example delivery policy is:
{"http":{"defaultHealthyRetryPolicy": {"minDelayTarget": 1, "maxDelayTarget": 5, "numRetries": 5, "numMaxDelayRetries": 5, "backoffFunction": "linear"}}}
subscribe Method
Request a subscription to the specific topic.
Syntax
def subscribe(topic_arn: str, endpoint: str, endpoint_protocol: int) -> str: ...
Remarks
This method requests a subscription to the topic specified by TopicArn. If the subscription was created immediately without requiring confirmation the SubscriptionArn will be returned by this method. The SubscriptionArn will begin with "arn:aws:sns". SubscriptionArn may be used with the following methods:
If the subscription requires confirmation this method returns the subscription status such as "pending confirmation".
The Endpoint and EndpointProtocol parameters specify how the subscription confirmation message is delivered. Possible values for EndpointProtocol are:
| 0 (email) | message via SMTP |
| 1 (email-json) | JSON-encoded message via SMTP |
| 2 (http) | JSON-encoded message via HTTP POST |
| 3 (https) | JSON-encoded message via HTTPS POST |
| 4 (sms) | message via SMS |
| 5 (sqs) | JSON-encoded message to an Amazon SQS queue |
The Endpoint parameter format depends on the chosen EndpointProtocol. Possible formats are:
| A valid e-mail address | for use with the "email" protocol |
| A valid e-mail address | for use with the "email-json" protocol |
| A URL beginning with "http://" | for use with the "http" protocol |
| A URL beginning with "https://" | for use with the "https" protocol |
| A phone number (e.g. 19195447070) | for use with the "sms" protocol |
| A SQS queue ARN | for use with the "sqs" protocol |
Once the subscription confirmation is received by the endpoint owner the confirm_subscription method must be called with the confirmation token to complete the subscription.
Note: Confirmation tokens are valid for 3 days.
unsubscribe Method
Unsubscribes from the topic.
Syntax
def unsubscribe(subscription_arn: str) -> None: ...
Remarks
This method deletes a subscription to a topic. The subscription is identified by the SubscriptionArn parameter.
If the subscription requires authentication for deletion, only the subscription owner or topic owner can unsubscribe. If authentication is not required a cancellation notice is sent to the endpoint, so that the endpoint owner can re-subscribe if the unsubscribe request was unintentional.
on_error Event
Fired when information is available about errors during data delivery.
Syntax
class AmazonSNSErrorEventParams(object): @property def error_code() -> int: ... @property def description() -> str: ... # In class AmazonSNS: @property def on_error() -> Callable[[AmazonSNSErrorEventParams], None]: ... @on_error.setter def on_error(event_hook: Callable[[AmazonSNSErrorEventParams], None]) -> None: ...
Remarks
The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
on_log Event
This event fires once for each log message.
Syntax
class AmazonSNSLogEventParams(object): @property def log_level() -> int: ... @property def message() -> str: ... @property def log_type() -> str: ... # In class AmazonSNS: @property def on_log() -> Callable[[AmazonSNSLogEventParams], None]: ... @on_log.setter def on_log(event_hook: Callable[[AmazonSNSLogEventParams], None]) -> None: ...
Remarks
This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
| 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).
Message is the log entry.
LogType identifies the type of log entry. Possible values are as follows:
- "Info"
- "RequestHeaders"
- "ResponseHeaders"
- "RequestBody"
- "ResponseBody"
- "ProxyRequest"
- "ProxyResponse"
- "FirewallRequest"
- "FirewallResponse"
on_ssl_server_authentication Event
Fired after the server presents its certificate to the client.
Syntax
class AmazonSNSSSLServerAuthenticationEventParams(object): @property def cert_encoded() -> bytes: ... @property def cert_subject() -> str: ... @property def cert_issuer() -> str: ... @property def status() -> str: ... @property def accept() -> bool: ... @accept.setter def accept(value) -> None: ... # In class AmazonSNS: @property def on_ssl_server_authentication() -> Callable[[AmazonSNSSSLServerAuthenticationEventParams], None]: ... @on_ssl_server_authentication.setter def on_ssl_server_authentication(event_hook: Callable[[AmazonSNSSSLServerAuthenticationEventParams], None]) -> None: ...
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.
on_ssl_status Event
Fired when secure connection progress messages are available.
Syntax
class AmazonSNSSSLStatusEventParams(object): @property def message() -> str: ... # In class AmazonSNS: @property def on_ssl_status() -> Callable[[AmazonSNSSSLStatusEventParams], None]: ... @on_ssl_status.setter def on_ssl_status(event_hook: Callable[[AmazonSNSSSLStatusEventParams], None]) -> None: ...
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
on_subscription_list Event
Fires with information about the subscription.
Syntax
class AmazonSNSSubscriptionListEventParams(object): @property def subscription_arn() -> str: ... @property def topic_arn() -> str: ... @property def owner() -> str: ... @property def endpoint() -> str: ... @property def protocol() -> int: ... # In class AmazonSNS: @property def on_subscription_list() -> Callable[[AmazonSNSSubscriptionListEventParams], None]: ... @on_subscription_list.setter def on_subscription_list(event_hook: Callable[[AmazonSNSSubscriptionListEventParams], None]) -> None: ...

Remarks
This event fires once for each topic returned from a call to list_topics.
TopicARN identifies the current topic.
AmazonSNS Config Settings
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.SNS Config Settings
Amazon defines each version as the date it was released. An example is: "2009-07-15".
Possible values are:
- 0 (string - default)
- 1 (number)
- 2 (binary)
Valid array indices are from 0 to MessageAttributeCount - 1.
Valid array indices are from 0 to MessageAttributeCount - 1.
Valid array indices are from 0 to MessageAttributeCount - 1.
sns1.Config("PhoneNumber=+19191234567");
sns1.Publish("","","message");
sns1.Config("TargetArn=myArn");
sns1.Publish("","subject","message");
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 fails with an error 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 auth_scheme 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 fails with an error.
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 on_redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the on_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 fails with an error 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/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).
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. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001. In the C++ Edition for Windows, the *W version of the class must be used. For instance, DNSW or HTTPW.
Note: This setting is applicable only to Mac/iOS editions.
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.
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 multi-homed 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 local_host 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 multi-homed 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 local_port after the connection is established.
local_port cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in 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 on_data_in 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 on_data_in 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.

Note: This value is not applicable in Java.
By default, this config is set to false.
| 0 | IPv4 Only |
| 1 | IPv6 Only |
| 2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the on_ssl_status event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if ssl_provider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
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.
The value is formatted as a list of paths separated by semicolons. The class will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server or client certificates.
The default value is:
/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
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 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported 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 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 only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the on_ssl_status event.
Use this 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 config setting.
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.
Example values when ssl_provider is set to Platform:
obj.config("SSLEnabledCipherSuites=*");

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 value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
| TLS1.3 | 12288 (Hex 3000) |
| TLS1.2 | 3072 (Hex C00) (Default) |
| TLS1.1 | 768 (Hex 300) (Default) |
| TLS1 | 192 (Hex C0) (Default) |
| SSL3 | 48 (Hex 30) [Platform Only] |
| SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the class will use the internal TLS implementation when the ssl_provider is set to Automatic for all editions.
In editions which are designed to run on Windows ssl_provider 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 only supported 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 only available 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 the above 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 ssl_provider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and ssl_provider needs to be set to platform.
This setting is only applicable when ssl_provider is set to Internal.
If set to True all certificates returned by the server will be present in the Encoded parameter of the on_ssl_server_authentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
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 traffice for debugging purposes. When writing to this file the class will only append, it will not overwrite previous values.
Note: This setting is only applicable when ssl_provider is set to Internal.

This functionality is currently not available when the provider is OpenSSL.
The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the class will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the class fails with an error.
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 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.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this 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 ssl_provider 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 setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified 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:
