Class RSASignature

java.lang.Object

java.security.SignatureSpi

com.tencent.kona.sun.security.ssl.RSASignature

public final class RSASignature
extends java.security.SignatureSpi

Signature implementation for the SSL/TLS RSA Signature variant with both MD5 and SHA-1 MessageDigests. Used for explicit RSA server authentication (RSA signed server key exchange for RSA_EXPORT and DHE_RSA) and RSA client authentication (RSA signed certificate verify message). It conforms to the standard JCA Signature API. It is registered in the SunJSSE provider to avoid more complicated getInstance() code and negative interaction with the JCA mechanisms for hardware providers. The class should be instantiated via the getInstance() method in this class, which returns the implementation from the preferred provider. The internal implementation allows the hashes to be explicitly set, which is required for RSA client authentication. It can be obtained via the getInternalInstance() method. This class is not thread safe.
