keystone.common.password_hashers.bcrypt module

class keystone.common.password_hashers.bcrypt.Bcrypt

Bases: PasswordHasher

passlib transition class for implementing bcrypt password hashing

static hash(password: bytes, rounds: int = 12, **kwargs) → str

Generate password hash string with ident and params

https://pypi.org/project/bcrypt/

Parameters:

• password (bytes) – Password to be hashed.

• round (int) – Count of rounds.

Returns:

String in format $2b${rounds}${salt}{digest}

ident_values: set[str] = {'$2$', '$2a$', '$2b$', '$2x$', '$2y$'}

name: str = 'bcrypt'

static verify(password: bytes, hashed: str) → bool

Verify hashing password would be equal to the hashed value

Parameters:

• password (bytes) – Password to verify

• hashed (string) – Hashed password. Used to extract hashing parameters

Returns:

boolean whether hashing password with the same parameters would match hashed value
