About Cryptographic Hashing

Cryptographic hash functions produce a fixed-size digest from any input. SHA-256 is used in Bitcoin, TLS certificates, and file integrity checks. SHA-1, while deprecated for security, is still used in git commits. SHA-512 offers higher security for password hashing and digital signatures.

This tool uses the Web Crypto API built into your browser — the most secure way to generate hashes client-side. No data leaves your machine. Useful for verifying file checksums, generating content fingerprints, and testing hash-based authentication flows.
