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

• Rule ID: go_lang_weak_password_encryption_sha1
• Languages: go
• Source: weak_password_encryption_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. This algorithm is no longer considered secure and can make your system vulnerable.

  sha1.Sum([]byte('password')) // unsafe

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

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

Associated CWE

• CWE-326: Inadequate Encryption Strength

OWASP Top 10

• A02:2021 - Cryptographic Failures
