Is it worth (?possible?) making the number of rounds a configurable parameter rather than hard-coding it to 20? (this confused me when I tried some of the other IETF test vectors and the output didn't match until I realised they were for a different number of rounds) |

To make the number of rounds configurable rather than using the default and to match all the test vectors, we’d also need configurable word size. That would take me another few days, but it’s probably worth it to support the full parameterisation. |
Add RC6 block cipher encrypt/decrypt operations. RC6 is a symmetric block cipher designed by Ron Rivest et al. It was an AES finalist and supports 128/192/256-bit keys. Features: - ECB, CBC, CFB, OFB, CTR modes - Multiple padding options (PKCS7, Zero, None) - 128-bit block size, 20 rounds Includes official test vectors from IETF draft.
