Usage of weak hashing library on a password (SHA-1)

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

Description

Using a weak hashing library like SHA-1 for passwords increases the risk of data breaches. SHA-1 is vulnerable to collision attacks, where two different inputs can produce the same hash value, compromising data integrity and security.

Remediations

• Do not use SHA-1 for hashing passwords or sensitive data due to its vulnerabilities.

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

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

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