Weak encryption algorithm (SHA1) used for password detected.

• Rule ID: python_lang_weak_password_encryption_sha1
• Languages: python
• Source: weak_password_encryption_sha1.yml

Description

A weak hashing library can lead to data breaches and greater security risk.

Remediations

According to OWASP, sha1 and its predecessors are considered weak hash algorithms and therefore shouldn't be used.

❌ Do not use encryption for passwords, wherever possible:

hashlib.sha1(user.password).digest()

✅ Instead, we recommend using sha256:

hashlib.sha256(user.password).digest()

Associated CWE

• CWE-331: Insufficient Entropy
