Yescrypt

✓ from pyescrypt import Yescrypt

✗ from yescrypt import Yescrypt

The package is named pyescrypt, not yescrypt.

Hash and verify a password using yescrypt with default parameters.

from pyescrypt import Yescrypt yescrypt = Yescrypt() password = b"correct horse battery staple" salt = b"unique_salt" hashed = yescrypt.hash(password, salt) print("Hashed:", hashed.hex()) verified = yescrypt.verify(password, salt, hashed) print("Verified:", verified)

Debug

Known issues

gotchaThe hash output is raw bytes (not a string). You are responsible for encoding (e.g., hex) for storage.

fix

Use .hex() on the hash bytes before storing, and .fromhex() when loading.

affects: >=0.1.0

deprecatedThe verify method currently returns True/False. The signature may change in future versions to raise exceptions for invalid input.

fix

Check return value and handle explicitly; watch for updates.

affects: 0.1.0

gotchaNo default parameters for memory cost, block size, or parallelism. You must pass them or accept library defaults that may be weak.

fix

Always specify parameters: hash(password, salt, N=2**14, r=8, p=1) for recommended settings.

affects: >=0.1.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'yescrypt'

Importing using the package name instead of the actual module name.

fix

Use 'from pyescrypt import Yescrypt' (package is pyescrypt).

AttributeError: 'bytes' object has no attribute 'hex'

Python 3.4 or earlier (hex method added in 3.5).

fix

Upgrade to Python 3.5+ or use binascii.hexlify().

cffi.error.CDefError: cannot parse '...'

Missing shared library libyescrypt or incompatible version.

fix

Install libyescrypt from your system package manager (e.g., apt install libyescrypt-dev).
