MD
Message Digest algorithms (MD2, MD4, MD5)
The MD family covers MD2, MD4 and MD5, the 128-bit digests still found in legacy checksums, file indexes and older protocols. Each algorithm has a text version and a file version. All three are cryptographically broken, so use them to match existing values – never to protect passwords or sign data.
