HASHING

Input text
HMAC key (optional — leave blank to compute plain hashes)
Algorithms
MD5 SHA-1 SHA-256 SHA-512 SHA3-256 CRC32 NTLM

Note: HMAC does not support CRC32, MD5, or NTLM in the browser (Web Crypto limitation). Those will show plain hashes.

Test vectors — verify known values

Click a vector to load it, then run HASH to verify.

Hash identifier

Paste a hash string to identify its likely algorithm by length and character set.
