Free Hash Generator — MD5, SHA1, SHA256, SHA512 Online

Algorithm Text

How to use

Checksums and integrity checks. Do not use MD5/SHA1 for security.

What hashes are supported?

MD5, SHA-1, SHA-256, and SHA-512. For new applications prefer SHA-256 or SHA-512; MD5 and SHA-1 are weak for security.

Can I hash a file?

This tool hashes text input. For file hashing you’d upload the file and we’d compute the hash of its bytes (could be added as a feature).

Is hashing reversible?

No. Hashes are one-way. Same input always gives the same hash; you can’t get the input back from the hash.
