Hash Generator - MD5, SHA-1, SHA-256, SHA-512
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from text
MD5 and SHA-1 are cryptographically broken - use them only for non-security checksums. For passwords use bcrypt/argon2.
Comment ça marche
- 1Paste your text
Drop any text - a password, a file's contents, an API response.
- 2See all hashes
MD5, SHA-1, SHA-256, and SHA-512 appear simultaneously.
- 3Copy or compare
Copy any hash or paste a hash to compare against for verification.

Questions fréquentes
Is MD5 secure?
No. MD5 and SHA-1 are cryptographically broken and should never be used for security. They're still useful for non-security checksums (file integrity, cache keys).
Which hash should I use?
For passwords, don't use these - use bcrypt or argon2. For file integrity, SHA-256 is the modern default.
Is my input uploaded?
Never. Hashing runs entirely in your browser via the Web Crypto SubtleCrypto API.
Can I hash a file?
This tool takes text input. For files, most operating systems have a built-in checksum command (shasum on macOS/Linux, CertUtil on Windows).
