【Introduction to MD5】

Message Digest Algorithm MD5 (Chinese name: Message Digest Algorithm Version 5) is a hash function widely used in the field of computer security to provide message integrity protection. The document number of this algorithm is RFC 1321 (R. Rivest, MIT Laboratory for Computer Science and RSA Data Security Inc. April 1992).

MD5 is Message-Digest Algorithm 5 (Message-Digest Algorithm 5), which is used to ensure complete and consistent information transmission. It is one of the hash algorithms widely used in computers (also translated as digest algorithm and hash algorithm). MD5 is generally implemented in mainstream programming languages. Computing data (such as Chinese characters) into another fixed-length value is the basic principle of the hash algorithm. The predecessors of MD5 include MD2, MD3 and MD4.

The MD5 algorithm has the following characteristics:

1. Compressibility: For data of any length, the length of the calculated MD5 value is fixed.

2. Easy to calculate: It is easy to calculate the MD5 value from the original data.

3. Anti-modification: If any changes are made to the original data, even if only 1 byte is modified, the resulting MD5 value will be very different.

4. Strong anti-collision: Given the original data and its MD5 value, it is very difficult to find data with the same MD5 value (ie, forged data).

The function of MD5 is to allow large-capacity information to be "compressed" into a confidential format (that is, to convert a byte string of any length into a string of hexadecimal digits of a certain length) before signing the private key with digital signature software. In addition to MD5, the more famous ones include sha-1, RIPEMD and Haval.
