Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text in your browser. Instant, private hash generator.

How to use this hash generator
Paste text and pick an algorithm. SHA family hashes use the Web Crypto API. MD5 uses a compact local implementation because browsers do not expose MD5.
Hashes are one-way. Use this for checksums and cache keys, not for storing passwords—use a password hashing scheme such as Argon2 or bcrypt on a server.
Example
SHA-256 of hello is 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824.

Frequently asked questions
Which hash algorithms are included?
MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Prefer SHA-256 or SHA-512 for new work.
Is MD5 secure?
No for security. It is still used for casual checksums. Do not use MD5 or SHA-1 for signatures or password storage.
Is the text hashed locally?
Processed locally in your browser. We do not upload the text to compute a result.
Hex or Base64?
Output is lowercase hex. Encode the hex as you like with the Base64 encoder if a system wants Base64.
