public static final int deduceKeyLength(String cipherSuite)

Given the name of a TLS/SSL cipher suite, return an int representing it effective stream cipher key strength. i.e. How much entropy material is in the key material being fed into the encryption routines.

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

                        Effective 
    Cipher       Type    Key Bits 

    NULL       * Stream     0     
    IDEA_CBC     Block    128     
    RC2_CBC_40 * Block     40     
    RC4_40     * Stream    40     
    RC4_128      Stream   128     
    DES40_CBC  * Block     40     
    DES_CBC      Block     56     
    3DES_EDE_CBC Block    168
Parameters
cipherSuite:String

String name of the TLS cipher suite.

Returns:int

int indicating the effective key entropy bit-length.
