Usage of weak hashing library (SHA-1)

• Rule ID: go_lang_weak_hash_sha1
• Languages: go
• Source: weak_hash_sha1.yml

Description

Using a weak hashing library such as SHA-1 can compromise data security. SHA-1 is no longer considered secure due to vulnerabilities that can lead to data breaches.

Remediations

• Do not use SHA-1 for hashing. It is considered weak and vulnerable to attacks.

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

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

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

Associated CWE

• CWE-328: Use of Weak Hash

OWASP Top 10

• A02:2021 - Cryptographic Failures
