Method Nettle.Hash()->crypt_hash()

Method crypt_hash

string(7bit) crypt_hash(string(8bit) password, string(8bit) salt, int(0..) rounds)

Description

Password hashing function in crypt_md5()-style.

Implements the algorithm described in http://www.akkadia.org/drepper/SHA-crypt.txt.

This is the algorithm used by crypt(2) in methods $5$ (SHA256) and $6$ (SHA512).

The password memory will be cleared before released.

Rounds will never be set to less than 1000. If rounds is 0 it will be set to 5000.

Note

In Pike 8.0.1876 and earlier this function generated incompatible hashes for passwords that had a length that was a power of 2. See crypt_hash_pike() for details.
