Package crypt provides wrappers around functions available in crypt.h

It wraps around the GNU specific extension (crypt_r) when it is available (i.e. where GOOS=linux). This makes the go function reentrant (and thus callable from concurrent goroutines).

• func CryptSHA512(phrase string) (string, error)
• func PasswordIsCrypted(s string) bool

Functions

func CryptSHA512

func CryptSHA512(phrase string) (string, error)

CryptSHA512 encrypts the given password with SHA512 and a random salt.

Note that this function is not deterministic.

func PasswordIsCrypted

func PasswordIsCrypted(s string) bool

PasswordIsCrypted returns true if the password appears to be an encrypted one, according to a very simple heuristic.

Any string starting with one of $2$, $6$ or $5$ is considered to be encrypted. Any other string is consdirede to be unencrypted.

This functionality is taken from pylorax.
