The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, and was specified in 1992 as RFC 1321.

MD5 can be used as a checksum to verify data integrity against unintentional corruption. Historically it was widely used as a cryptographic hash function; however it has been found to suffer from extensive vulnerabilities. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database, and may be preferred due to lower computational requirements than more recent Secure Hash Algorithms.

MD5 Encrypt is a process of using the MD5 algorithm to transform a string of any length into a hash. The hash is also known as a fingerprint or a digest of the original string. MD5 Encrypt is often used to secure sensitive data such as passwords, credit card numbers, or file contents in databases or online applications. MD5 Encrypt can also be used to verify the integrity of files by comparing the hashes of the source and the destination files. MD5 Encrypt is not reversible, meaning that it is very difficult to recover the original string from the hash. However, MD5 Encrypt is also not collision-resistant, meaning that different strings can produce the same hash. Therefore, MD5 Encrypt is not recommended for cryptographic purposes, but rather for checksums or identifiers.
