Script Function
The script is written in Perl to calculate the MD5 value of the file.
Script usage
After installing the operating system, the server calculates the MD5 values of all the binary files in the PATH variable, calculates the MD5 values of
the MD5 algorithm has the following characteristics:1, compressibility: Any length of data, calculated the length of the MD5 value is fixed. 2, easy to calculate: It is easy to calculate the MD5 value from the original data. 3, anti-modification:
MD5 Introduction
MD5 's full name, Message-digest algorithm 5, was developed by the MIT Computer Science Lab and RSA Data Security Inc in the early 90, through MD2, MD3 and MD4.
Message-digest refers to the hash transformation of a byte string
