Multiple File Checksums.
Compute MD5, SHA-1, SHA-256 and SHA-512 for a local file.
How to use Multiple File Checksums
Choose the input, adjust settings and generate locally. Inspect the exported result before sharing.
How it works
Compute MD5, SHA-1, SHA-256 and SHA-512 for a local file. MD5 and SHA-1 are legacy checksums, unsuitable for security authenticity. Hashing alone does not prove who created a file. Documents remain on your device.
Example
Choose a local file or use the displayed editable text example.
