Is the hash generated locally?

Yes, the hashing uses the Web Crypto API locally. Your text is never sent to a server.

Can a hash be decrypted?

No, cryptographic hashes are one-way functions. They cannot be 'decrypted' back into the original text.

Generate cryptographic hashes instantly using MD5, SHA-1, SHA-256, SHA-512, SHA-3, RIPEMD-160, and HMAC.

Select a cryptographic algorithm (like SHA-256 or MD5) and type your text. The tool calculates the hash hash digest instantly in your browser.

MD5 is insecure and vulnerable to collision attacks. Always use strong, salted hashes like bcrypt, Argon2, or at least SHA-256 for security purposes.
