Weak hashing library (SHA-1) detected

• Rule ID: java_lang_weak_password_hash_sha1
• Languages: java
• Source: weak_password_hash_sha1.yml

Description

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

Remediations

According to OWASP, SHA1 is considered a weak hashing algorithms and therefore shouldn't be used.

❌ Avoid libraries and algorithms with known weaknesses:

  MessageDigest md = MessageDigest.getInstance("SHA-1");

✅ Use stronger encryption algorithms when storing data.

  MessageDigest md = MessageDigest.getInstance("SHA-256");

Resources
