Usage of weak hashing library on a password (MD5)

• Rule ID: java_lang_weak_password_hash_md5
• Languages: java
• Source: weak_password_hash_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 MD5 is outdated and vulnerable, making it easier for attackers to crack passwords and gain unauthorized access.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 or any sensitive data. It is no longer considered secure.

  MessageDigest md = MessageDigest.getInstance("MD5"); // unsafe

• Do opt for stronger hashing algorithms such as SHA-256 to enhance the security of stored data.

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