Field Detail

• strongSuites

  public static final List<String> strongSuites

  The strong supported suites in an unmodifiable list. The suites depends of the Java version.

• strongSuitesString

  public static final String strongSuitesString

  The strong cipher suites as a comma separated string. The suites depends of the Java version.

• allSuites

  public static final List<String> allSuites

  All supported suites in an unmodifiable list. The suites depends of the Java version.

• supportedProtocols

  public static final List<String> supportedProtocols

  Supported protocols: SSLv3, TLSv1, TLSv1.1, TLSv1.2, TLSv1.3 (depends on JVM),... The protocols depends of the Java version.

• strongProtocols

  public static final List<String> strongProtocols

  List of strong supported protocols: TLSv1.2, ... The protocols depends of the Java version.

Constructor Detail

• NetPhantomCipherSuites

  public NetPhantomCipherSuites()

Method Detail

• isStrongProtocol

  public static boolean isStrongProtocol(String protocol)

  Checks if it's a strong protocol. It is strong if it's not SSL*, not TLSv1, not TLSv1.1.

  Parameters:

  protocol - Protocol.

  Returns:

  true if strong, false otherwise.

• isStrongSuite

  public static boolean isStrongSuite(String s)

  Checks if a suite is strong.

  Parameters:

  s - The cipher suite.

  Returns:

  true if strong cipher suite, false if considered weak. true is also returned for the "*_RENEGOTIATION_*" cipher suite.

• getStrength

  public static int getStrength(String s)

  Gets strength: 256, 128 or less:

  This is based on the information on effective key lengths in RFC 2246 - The TLS Protocol Version 1.0, Appendix C. CipherSuite definitions:

    Cipher        Type    Key Bits
    ------------  ------- ---------
    3DES_EDE_CBC  Block      168
    RC4_128       Stream     128
    IDEA_CBC      Block      128
    DES_CBC       Block       56
    RC2_CBC_40 *  Block       40
    RC4_40     *  Stream      40
    DES40_CBC  *  Block       40
    NULL       *  Stream       0
   

  Parameters:

  s - The cipher suite.

  Returns:

  The effective key entropy bit-length: 256, 168, 128, 56, 40 or 0 if unknown.

• main

  public static void main(String[] args)

  When called, it will list, for the JVM in question, the cipher suites supported, the strong ones in order of importance. The supported protocols and the strong ones are also listed.

  Parameters:

  args - The arguments, ignored...
