FAQ
What is SHA-1?
SHA-1 produces a 160-bit (40 hex character) hash. It's used for legacy checksum verification but is no longer recommended for security-sensitive applications.
Is SHA-1 still secure?
SHA-1 has known collision vulnerabilities. For security purposes, use SHA-256 or SHA-512 instead.
Can I compute other hash types?
Yes, the Hash Checker computes SHA-1, SHA-256, and SHA-512 simultaneously.
Is this free?
Yes, 100% free with no sign-up required.
