Are there hash algorithms with variable length output? thanks for your response. What did you mean by, "make sure to first remove the IV?" In Node.js, if you pass a "password" into the Cipher's constructor, a key and IV is derived using EVP_BytesToKey. This means that the IV won't be random, but isn't that the idea? If the IV was random, you wouldn't get consistent, predictable hash results? |

Are there hash algorithms with variable length output? This might be a silly question, but can you pass a zero-filled buffer as plain-text (of size b bits) to an AES block cipher (say CBC or whatever), use the SHA-256 hash to derive the key and initialization vector, and then take the first b bits of cipher-text to be used as your output? Is this just as secure? See gist.github.com/4600432 for Node.js implementation. |
