var ErrHashTooShort = errors.New("crypto/bcrypt: hashedSecret too short to be a bcrypted password")

The error returned from CompareHashAndPassword when a hash is too short to be a bcrypt hash.

golang.org/x/crypto/bcrypt/bcrypt.go:33

var ErrMismatchedHashAndPassword = errors.New("crypto/bcrypt: hashedPassword is not the hash of the given password")

The error returned from CompareHashAndPassword when a password and hash do not match.

golang.org/x/crypto/bcrypt/bcrypt.go:29

var ErrPasswordTooLong = errors.New("bcrypt: password length exceeds 72 bytes")

ErrPasswordTooLong is returned when the password passed to GenerateFromPassword is too long (i.e. > 72 bytes).

func CompareHashAndPassword(hashedPassword []byte, password []byte) error

CompareHashAndPassword compares a bcrypt hashed password with its possible plaintext equivalent. Returns nil on success, or an error on failure.

golang.org/x/crypto/bcrypt/bcrypt.go:108

func Cost(hashedPassword []byte) (int, error)

Cost returns the hashing cost used to create the given hashed password. When, in the future, the hashing cost of a password system needs to be increased in order to adjust for greater computational power, this function allows one to establish which passwords need to be updated.

golang.org/x/crypto/bcrypt/bcrypt.go:131

func GenerateFromPassword(password []byte, cost int) ([]byte, error)

GenerateFromPassword returns the bcrypt hash of the password at the given cost. If the cost given is less than MinCost, the cost will be set to DefaultCost, instead. Use CompareHashAndPassword, as defined in this package, to compare the returned hashed password with its cleartext version. GenerateFromPassword does not accept passwords longer than 72 bytes, which is the longest password bcrypt will operate on.
