带有python passlib的Spring兼容scrypt密码

如何从python生成与Spring兼容的密码?

{scrypt}$e0801$qaqc0fvhy6ijpysiqsfnorcug205njho/6o+idxdn33lxmzocvbhb4naqdafhugmykcxqtmi5xp5zb57mymur3q==$sBeXCHOm6zQuGdSDKs+HeXnNQGg3bhRidmL+HU/ZTMM=

我正在尝试使用python和passlib直接用新密码更新数据库,但是无法预测passlib的正确设置 $e0801$ :

>>> from passlib.hash import scrypt
>>> scrypt.verify('wBkfoBsxj9u3wLOZ', '{scrypt}$e0801$QAqC0fvhY6iJPysiQsFnrcUg205njHo/6o+IDXDn33lxmZOCVBhb4NAqdafhuGmykCxQtMI5xP5zb7MYMUrU3Q==$sBeXCHOm6zQuGdSDKs+HeXnNQGg3bhRidmL+HU/ZTMM=')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/gregn/.pyenv/versions/v2.7.16/lib/python2.7/site-packages/passlib/utils/handlers.py", line 789, in verify
    self = cls.from_string(hash, **context)
  File "/home/gregn/.pyenv/versions/v2.7.16/lib/python2.7/site-packages/passlib/handlers/scrypt.py", line 177, in from_string
    return cls(**cls.parse(hash))
  File "/home/gregn/.pyenv/versions/v2.7.16/lib/python2.7/site-packages/passlib/handlers/scrypt.py", line 181, in parse
    ident, suffix = cls._parse_ident(hash)
  File "/home/gregn/.pyenv/versions/v2.7.16/lib/python2.7/site-packages/passlib/utils/handlers.py", line 1207, in _parse_ident
    raise exc.InvalidHashError(cls)
ValueError: not a valid scrypt hash

手动修改前缀格式无效:

>>> scrypt.verify('wBkfoBsxj9u3wLOZ', '$scrypt$ln=1,r=8,p=1$QAqC0fvhY6iJPysiQsFnrcUg205njHo/6o+IDXDn33lxmZOCVBhb4NAqdafhuGmykCxQtMI5xP5zb7MYMUrU3Q==$sBeXCHOm6zQuGdSDKs+HeXnNQGg3bhRidmL+HU/ZTMM=')
False

我认为(但不确定)Spring正在使用默认的scryptppasswordencoder设置,因为我发现:

public static PasswordEncoder getPasswordEncoder() {
    final String encodingId = "scrypt";
    final Map<String, PasswordEncoder> encoders = new HashMap<>();
    encoders.put("bcrypt", new BCryptPasswordEncoder());
    encoders.put(encodingId, new SCryptPasswordEncoder());
    return new DelegatingPasswordEncoder(encodingId, encoders);
}
