Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes and HMACs from any text or file, and compare two hashes. Everything runs in your browser.

Examples:

JSON Formatter

Paste JSON to format, minify, or validate it instantly. All processing happens in your browser - no data is transmitted.

UUID / ULID

Generate, validate and decode UUID v4, v7, v1, v5 and ULID in your browser, with no server. A UUID you validate goes into the page address so you can share it.

Password Strength

Check how strong your password is. Your password is never sent to our server - all analysis runs in your browser.

About this tool

This tool computes four widely used cryptographic hash functions. MD5 and SHA-1 are computed using a pure JavaScript implementation because the Web Crypto API does not support them. SHA-256 and SHA-512 use the browser built-in crypto.subtle.digest for maximum performance.

MD5 and SHA-1 are considered cryptographically broken and should not be used for security-sensitive applications. They remain useful for checksums and data integrity checks where collision resistance is not required. For security use cases, prefer SHA-256 or SHA-512.
