    • setVerify

      public static void setVerify(long ssl, int level, int depth)
      Set Type of Client Certificate verification and Maximum depth of CA Certificates in Client Certificate verification.
      This directive sets the Certificate verification level for the Client Authentication. Notice that this directive can be used both in per-server and per-directory context. In per-server context it applies to the client authentication process used in the standard SSL handshake when a connection is established. In per-directory context it forces an SSL renegotiation with the reconfigured client verification level after the HTTP request was read but before the HTTP response is sent.
      The following levels are available for level: 
       SSL_CVERIFY_NONE           - No client Certificate is required at all
 SSL_CVERIFY_OPTIONAL       - The client may present a valid Certificate
 SSL_CVERIFY_REQUIRE        - The client has to present a valid Certificate
 SSL_CVERIFY_OPTIONAL_NO_CA - The client may present a valid Certificate
                              but it need not to be (successfully) verifiable

      The depth actually is the maximum number of intermediate certificate issuers, i.e. the number of CA certificates which are max allowed to be followed while verifying the client certificate. A depth of 0 means that self-signed client certificates are accepted only, the default depth of 1 means the client certificate can be self-signed or has to be signed by a CA which is directly known to the server (i.e. the CA's certificate is under setCACertificatePath, etc.
      Parameters:
      ssl - the SSL instance (SSL *)
      level - Type of Client Certificate verification.
      depth - Maximum depth of CA Certificates in Client Certificate verification.

    • setOptions

      public static void setOptions(long ssl, int options)

      Parameters:

    • getOptions

      public static int getOptions(long ssl)
      Get OpenSSL Option.
      Parameters:
      ssl - the SSL instance (SSL *)
      Returns:
      options See SSL.SSL_OP_* for option flags.

    • getCiphers

      public static String[] getCiphers(long ssl)
      Returns all cipher suites that are enabled for negotiation in an SSL handshake.
      Parameters:
      ssl - the SSL instance (SSL *)
      Returns:
      ciphers

    • setCipherSuites

      public static boolean setCipherSuites(long ssl, String ciphers) throws Exception
      Returns the cipher suites available for negotiation in SSL handshake.
      This complex directive uses a colon-separated cipher-spec string consisting of OpenSSL cipher specifications to configure the Cipher Suite the client is permitted to negotiate in the SSL handshake phase. Notice that this directive can be used both in per-server and per-directory context. In per-server context it applies to the standard SSL handshake when a connection is established. In per-directory context it forces an SSL renegotiation with the reconfigured Cipher Suite after the HTTP request was read but before the HTTP response is sent.
      Parameters:
      ssl - the SSL instance (SSL *)
      ciphers - an SSL cipher specification
      Returns:
      true if the operation was successful
      Throws:
      Exception - An error occurred

    • getSessionId

      public static byte[] getSessionId(long ssl)
