About this tool
Compute cryptographic digests of any text with MD5, SHA-1, SHA-256 and SHA-512, and produce keyed HMAC values for signing and verification. Every digest updates as you type.
Hashing runs locally in your browser, so your input and any secret key never leave the page. Typical uses include verifying file and download checksums, comparing values and generating webhook signatures. Note that MD5 and SHA-1 are fine for checksums but should not be relied on where collision resistance matters.
