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 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.

See Also:
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.
