Frequently Asked Questions
What are hashes used for?
Hashes are used for password verification, data integrity checks, file checksums, digital signatures, and identifying duplicate data.
Is SHA-1 still secure?
SHA-1 is considered cryptographically weak and should not be used for security-critical applications. Use SHA-256 or higher instead.
