Hash Generator

How it works

This tool runs entirely in your browser using the Web Crypto API (SubtleCrypto) for SHA hashes and a local JavaScript implementation for MD5. Your text never leaves your device.

Quick tips

• Hashes are one-way — you cannot recover the original text from a hash.
• SHA-256 is the recommended general-purpose hash for verification.
• MD5 and SHA-1 are considered cryptographically broken and should not be used for security-sensitive applications.
• Different algorithms produce different-length hashes: MD5 = 32 chars, SHA-1 = 40 chars, SHA-256 = 64 chars, SHA-512 = 128 chars.
