Usage of weak hashing library (DSS)

• Rule ID: python_lang_weak_hash_dss
• Languages: python
• Source: weak_hash_dss.yml

Description

Using a weak hashing library like DSS increases the risk of data breaches. DSS has known security flaws and vulnerabilities, and its use is no longer recommended.

Remediations

• Do not use DSS for hashing as it is considered a weak algorithm. This can compromise data security.

  hashlib.new('dss', data).digest() # unsafe

• Do opt for stronger hashing algorithms like SHA-256 to enhance security.

  hashlib.sha256(data).digest()

Associated CWE

• CWE-328: Use of Weak Hash

OWASP Top 10

• A02:2021 - Cryptographic Failures
