Check the signature algorithm for certificates in the peer's CertPath as specified in RFC 5246 7.4.2, 7.4.4, 7.4.6 and similar rules for earlier TLS versions. The supplied CertPath should include the trust anchor (its signature algorithm isn't checked, but in the general case checking a certificate requires the issuer certificate).

Throws:

java.io.IOException - if any certificate in the CertPath (excepting the trust anchor) has a signature algorithm that is not one of the locally supported signature algorithms.
