Hash Identifier
Identify the hash algorithm behind any hash by length, charset and pattern — MD5, SHA family, bcrypt and more.
Identification is by length/charset/structure — salts make hashes unsaid identical. MD5 is computed with a built-in RFC 1321 implementation; SHA family uses Web Crypto. Nothing leaves your browser.
