Quick steps so you can get results fast.
Type or paste the text to hash. Hashes are calculated from the exact characters, including spaces and line breaks.
Use SHA-256 or stronger for anything security-related; MD5 and SHA-1 are only suitable for checksums and legacy systems.
Compare the hex output with the value you expect. A single changed character gives a completely different hash.
Copy the hash. Recent results are listed in the history panel.
