MD5 or Message-Digest Algorithm 5 (Information- Digest Algorithm 5), used to ensure a complete and consistent information transfer. Widely used computer, one of hash algorithms (also translated digest algorithm, hash algorithm), mainstream programming languages have generally MD5 implementation. The data (such as Chinese characters) operator to another fixed-length hash value is the basis of principle of the algorithm, MD5' s predecessor are MD2, MD3, and MD4.
