| HMAC-SHA3 hasn't been specified yet. Once an official RFC or NIST document is out I can implement the correct block_size attribute and add test vectors. In the mean time I'm disabling SHA3 by returning NotImplemented from block_size. This ticket a reminder for myself. | ||

| HMAC-SHA3 hasn't been standardized yet. I'm not even sure their will be an official HMAC-SHA3 standard anytime soon. Keccak uses a sponge design that isn't vulnerable to length extension attacks like Merkle–Damgård based hashing algorithms (MD5, SHA-1, SHA-2). My standalone package now contains some experimental code and tests based on http://www.di-mgt.com.au/hmac_sha3_testvectors.html . |
