Important Security Notice
MD5 and SHA-1 are cryptographically broken and should not be used for security-critical applications. They are vulnerable to collision attacks and other cryptographic weaknesses.
Recommendation: Use SHA-256 or SHA-512 for new applications requiring cryptographic security. For legacy compatibility or non-security use cases, MD5 and SHA-1 may still be acceptable.
