Given the partial or complete certificate chain provided by the peer, build and validate the certificate path based on the authentication type and ssl parameters.
The authentication type is the key exchange algorithm portion of the cipher suites represented as a String, such as "RSA", "DHE_DSS". Note: for some exportable cipher suites, the key exchange algorithm is determined at run time during the handshake. For instance, for TLS_RSA_EXPORT_WITH_RC4_40_MD5, the authType should be RSA_EXPORT when an ephemeral RSA key is used for the key exchange, and RSA when the key from the server certificate is used. Checking is case-sensitive.
If the engine
parameter is available, and the endpoint identification algorithm of the SSLParameters
is non-empty, to prevent man-in-the-middle attacks, the address that the engine
connected to should be checked against the peer's identity presented in the end-entity X509 certificate, as specified in the endpoint identification algorithm.
If the engine
parameter is available, and the algorithm constraints of the SSLParameters
is non-null, for every certificate in the certification path, fields such as subject public key, the signature algorithm, key usage, extended key usage, etc. need to conform to the algorithm constraints in place on this engine.
