Types ¶
type Crypter ¶
type Crypter interface { // Generate performs the hashing algorithm, returning a full hash suitable // for storage and later password verification. // // If the salt is empty, a randomly-generated salt will be generated with a // length of SaltLenMax and number RoundsDefault of rounds. // // Any error only can be got when the salt argument is not empty. Generate(key, salt []byte) (string, error) // Verify compares a hashed key with its possible key equivalent. // Returns nil on success, or an error on failure; if the hashed key is // diffrent, the error is "ErrKeyMismatch". Verify(hashedKey string, key []byte) error // Cost returns the hashing cost (in rounds) used to create the given hashed // key. // // When, in the future, the hashing cost of a key needs to be increased in // order to adjust for greater computational power, this function allows one // to establish which keys need to be updated. // // The algorithms based in MD5-crypt use a fixed value of rounds. Cost(hashedKey string) (int, error) // SetSalt sets a different salt. It is used to easily create derivated // algorithms, i.e. "apr1_crypt" from "md5_crypt". SetSalt(salt common.Salt) }
Crypter is the common interface implemented by all crypt functions.
