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 name of the TLS cipher suite. int indicating the effective key entropy bit-length. |
