## How it works

Generate cryptographic fingerprints (hashes) from texts or files for integrity checks.

Choose between text or file mode and instantly get MD5, SHA-1, SHA-256, and SHA-512 values. Ideal for checking the authenticity of downloads.

Leverages the Web Crypto API for native SHA-1, SHA-256, and SHA-512 hashes. MD5 checksums and large files are processed chunk-by-chunk in memory.

## FAQ

### Which hash algorithms are supported?

Among others MD5, SHA-1, SHA-256 and SHA-512, for both text and files.

### How do I verify a download?

Drop the file into the tool and compare the checksum with the one on the download page. If they match, the file is unchanged.
