pwdlib также поддерживает алгоритм хеширования bcrypt, но не включает устаревшие алгоритмы — для работы с устаревшими хэшами рекомендуется использовать библиотеку passlib.

Например, вы можете использовать ее для чтения и проверки паролей, сгенерированных другой системой (например, Django), но хэшировать все новые пароли другим алгоритмом, например Argon2 или Bcrypt.

И при этом быть совместимым со всеми этими системами.

/// tip | Dica

pwdlib também oferece suporte ao algoritmo de hashing bcrypt, mas não inclui algoritmos legados – para trabalhar com hashes antigos, é recomendado usar a biblioteca passlib.

Por exemplo, você poderia usá-lo para ler e verificar senhas geradas por outro sistema (como Django), mas criar o hash de novas senhas com um algoritmo diferente, como o Argon2 ou o Bcrypt.

E ser compatível com todos eles ao mesmo tempo.
