FAQ

Is MD5 supported?

No. This tool uses Web Crypto SHA-1 and SHA-2 algorithms. For broader file checksum options, see the File Checksum tool.

How does HMAC mode relate to the dedicated HMAC generator?

This page can output multiple hash algorithms and optional HMAC together. The HMAC generator focuses on message/key signing with Hex and Base64 outputs.
