How to use
Type or paste text in the input box. MD5, SHA-1, SHA-256, and SHA-512 hashes are computed instantly. Toggle uppercase for capital letters. Click Copy next to any hash.
Why use this tool
Verify file integrity, check passwords, or explore cryptographic hashing. All computation is local using the Web Crypto API — no data ever leaves your browser.
FAQ
- Is MD5 secure for passwords?
- No. MD5 is cryptographically broken and unsuitable for password hashing. Use bcrypt or Argon2 instead. MD5 is still useful for checksums and file integrity.
- Which algorithm should I use?
- SHA-256 or SHA-512 for general security. SHA-1 is deprecated. MD5 is only for non-security checksums.
- Is my text sent to a server?
- No. Hashing uses the browser's built-in Web Crypto API and a local MD5 implementation. Nothing is transmitted.
