Methods

getLocalSupportedSignatureAlgorithms

public abstract String[] getLocalSupportedSignatureAlgorithms()

Obtains an array of supported signature algorithms that the local side is willing to use.

Note: this method is used to indicate to the peer which signature algorithms may be used for digital signatures since TLS 1.2. It is not meaningful for TLS versions prior to 1.2.

The signature algorithm name must be a standard Java Security name (such as "SHA1withRSA", "SHA256withECDSA", and so on). See Appendix A in the Java Cryptography Architecture API Specification & Reference for information about standard algorithm names.

Note: the local supported signature algorithms should conform to the algorithm constraints specified by getAlgorithmConstraints() method in SSLParameters.

Returns:
An array of supported signature algorithms, in descending order of preference. The return value is an empty array if no signature algorithm is supported.
See Also:
SSLParameters.getAlgorithmConstraints()

getPeerSupportedSignatureAlgorithms

public abstract String[] getPeerSupportedSignatureAlgorithms()

Obtains an array of supported signature algorithms that the peer is able to use.

Note: this method is used to indicate to the local side which signature algorithms may be used for digital signatures since TLS 1.2. It is not meaningful for TLS versions prior to 1.2.

The signature algorithm name must be a standard Java Security name (such as "SHA1withRSA", "SHA256withECDSA", and so on). See Appendix A in the Java Cryptography Architecture API Specification & Reference for information about standard algorithm names.

Returns:
An array of supported signature algorithms, in descending order of preference. The return value is an empty array if the peer has not sent the supported signature algorithms.

getRequestedServerNames

public List<SNIServerName> getRequestedServerNames()

Obtains a List containing all SNIServerNames of the requested Server Name Indication (SNI) extension.

In server mode, unless the return List is empty, the server should use the requested server names to guide its selection of an appropriate authentication certificate, and/or other aspects of security policy.

In client mode, unless the return List is empty, the client should use the requested server names to guide its endpoint identification of the peer's identity, and/or other aspects of security policy.

Returns:
a non-null immutable list of SNIServerNames of the requested server name indications. The returned list may be empty if no server name indications were requested.
Throws:
UnsupportedOperationException - if the underlying provider does not implement the operation

1.8
