About this tool

How it works

Compare the 64-character hexadecimal digest to a trusted checksum; this is not password encryption.
Any change in input changes the digest. SHA-256 is one-way and is not a password-encryption system.

Enter the exact text whose fingerprint you want, including its capitalization, spaces, and line breaks.

Example: hello
