Is PHP's password_hash FIPS compliant?

问题:

I believe hash('sha256', $pw) is FIPS compliant, but I know for certain that an attack vector is possible with using that function. Also, there is no salt (so I would have to encounter that implementation and I would rather not). Is password_hash/password_verify FIPS compliant?

回答1:

No.

1. FIPS 140-2 does not certify password hashing algorithms. As such, password_hash cannot be FIPS compliant, because FIPS simply doesn't apply to it.

2. To the best of my knowledge, the hash implementations used by hash() (which are part of the PHP core) have not been FIPS certified. If you specifically need a FIPS-compliant implementation, and you have a FIPS-compliant OpenSSL library installed, you may be able to use openssl_digest() as an alternative. (However, remember that this is not a secure method of storing passwords, even with a salt!)
