        public boolean isValidMessage​(java.lang.String username,
                                      byte[] message,

        Validate a message of a user.
        Parameters:
        username - name of the user
        message - the message
        signature - the signature
        algorithm - the digest algorithm
        Returns:
        true if the message is valid
      • checkClientTrusted

        public void checkClientTrusted​(java.security.cert.X509Certificate[] chain,
                                       java.lang.String authType)
                                throws java.security.cert.CertificateException
        Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for client SSL authentication based on the authentication type. The authentication type is determined by the actual certificate used. For instance, if RSAPublicKey is used, the authType should be "RSA". Checking is case-sensitive.
        Specified by:
        checkClientTrusted in interface javax.net.ssl.X509TrustManager
        Parameters:
        chain - the peer certificate chain
        authType - the authentication type based on the client certificate
        Throws:
        java.lang.IllegalArgumentException - if null or zero-length chain is passed in for the chain parameter or if null or zero-length string is passed in for the authType parameter
        java.security.cert.CertificateException - if the certificate chain is not trusted by this TrustManager.
      • checkServerTrusted

        public void checkServerTrusted​(java.security.cert.X509Certificate[] chain,
                                       java.lang.String authType)
                                throws java.security.cert.CertificateException
        Given the partial or complete certificate chain provided by the peer, build a certificate path to a trusted root and return if it can be validated and is trusted for server SSL authentication based on the authentication type. 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.
        Specified by:
        checkServerTrusted in interface javax.net.ssl.X509TrustManager
        Parameters:
        chain - the peer certificate chain
        authType - the key exchange algorithm used
        Throws:
        java.lang.IllegalArgumentException - if null or zero-length chain is passed in for the chain parameter or if null or zero-length string is passed in for the authType parameter
        java.security.cert.CertificateException - if the certificate chain is not trusted by this TrustManager.
      • getAcceptedIssuers

        public java.security.cert.X509Certificate[] getAcceptedIssuers()
        Return an array of certificate authority certificates which are trusted for authenticating peers.
        Specified by:
        getAcceptedIssuers in interface javax.net.ssl.X509TrustManager
        Returns:
        a non-null (possibly empty) array of acceptable CA issuer certificates.
