Usage of weak hashing library on a password (MD5)

• Rule ID: go_lang_weak_password_encryption_md5
• Languages: go
• Source: weak_password_encryption_md5.yml

Description

Using a weak hashing library like MD5 for password storage compromises security. MD5 is outdated and vulnerable, making it easier for attackers to crack passwords and gain unauthorized access.

Remediations

• Do not use MD5 for hashing passwords. This algorithm is no longer considered secure due to its vulnerability to collision and preimage attacks.

  md5.Sum([]byte('password')) // unsafe

• Do use stronger hashing algorithms such as SHA-256 for password hashing. These provide enhanced security and resistance against attacks.

  sha256.Sum256([]byte('string'))

Associated CWE

• CWE-326: Inadequate Encryption Strength

OWASP Top 10

• A02:2021 - Cryptographic Failures
