MD5 is a hash function widely used in the field of computer security to provide integrity protection for messages. The algorithm is used for ensuring the information transmission is complete and consistent. Is one of the hash algorithms (also known as digest algorithm and hash algorithm) widely used by computers, and the mainstream programming language is generally realized by MD 5. The operation of data (such as Chinese characters) into another fixed length value is the basic principle of the hash algorithm, and the precursors of MD5 include MD2, MD3 and MD 4.
MD5 functions to allow large volumes of information to be "compressed" into a secure format (i.e., a string of bytes of arbitrary length is converted into a fixed-length hexadecimal digital string) before the private key is signed by digital signature software.
