  - ### Method Detail

    - #### parse

          public static LinkedHashSet<Cipher> parse​(String expression)

    - #### convertForJSSE

          public static List<String> convertForJSSE​(Collection<Cipher> ciphers)

    - #### parseExpression

          public static List<String> parseExpression​(String expression)

      Parse the specified expression according to the OpenSSL syntax and returns a list of standard JSSE cipher names.
      Parameters:
        `expression` - the openssl expression to define a list of cipher.
      Returns:
        the corresponding list of ciphers.

    - #### jsseToOpenSSL

          public static String jsseToOpenSSL​(String jsseCipherName)

      Converts a JSSE cipher name to an OpenSSL cipher name.
      Parameters:
        `jsseCipherName` - The JSSE name for a cipher
      Returns:
        The OpenSSL name for the specified JSSE cipher

    - #### openSSLToJsse

          public static String openSSLToJsse​(String opensslCipherName)

      Converts an OpenSSL cipher name to a JSSE cipher name.
      Parameters:
        `opensslCipherName` - The OpenSSL name for a cipher
      Returns:
        The JSSE name for the specified OpenSSL cipher. If none is known, the IANA standard name will be returned instead
