Method Details

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 in TLS/DTLS 1.2. It is not meaningful for TLS/DTLS versions prior to 1.2.

The signature algorithm name must be a standard Java Security name (such as "SHA1withRSA", "SHA256withECDSA", and so on). See the Java Security Standard Algorithm Names document 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:

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 in TLS/DTLS 1.2. It is not meaningful for TLS/DTLS versions prior to 1.2.

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.

See Also:

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

Since:

1.8

See Also:

getStatusResponses

public List<byte[]> getStatusResponses()

Returns a List containing DER-encoded OCSP responses (using the ASN.1 type OCSPResponse defined in RFC 6960) for the client to verify status of the server's certificate during handshaking.

This method only applies to certificate-based server authentication. An X509ExtendedTrustManager will use the returned value for server certificate validation.

Implementation Requirements:

This method throws UnsupportedOperationException by default. Classes derived from ExtendedSSLSession must implement this method.

Returns:

a non-null unmodifiable list of byte arrays, each entry containing a DER-encoded OCSP response (using the ASN.1 type OCSPResponse defined in RFC 6960). The order of the responses must match the order of the certificates presented by the server in its Certificate message (See SSLSession.getLocalCertificates() for server mode, and SSLSession.getPeerCertificates() for client mode). It is possible that fewer response entries may be returned than the number of presented certificates. If an entry in the list is a zero-length byte array, it should be treated by the caller as if the OCSP entry for the corresponding certificate is missing. The returned list may be empty if no OCSP responses were presented during handshaking or if OCSP stapling is not supported by either endpoint for this handshake.

Throws:

UnsupportedOperationException - if the underlying provider does not implement the operation
