Java Cryptographic Decryption Message digest algorithm (MD5 SHA MAC)Message digestMessage Digest, also known as a Digital digest (digitally Digest).It is the only fixed-length value corresponding to a message or text that is generated by a one-way
Chapter 3 message digest algorithm-MD5, digest-md5
Note: In this section, refer to "verify data integrity-message digest algorithm" in Chapter 2nd of Java encryption and decryption art (version 6th"
3.1 message digest algorithm: prevents tampering
First of all we need to understand what CODEC means. It is Coder + Decoder = Codec, which is the encoder decoder. That is, the encoder is also the decoder.Website address: http://commons.apache.org/proper/commons-codec/Apache Commons Codec (TM)
I learned about MD5 encryption some time ago.Algorithm, You can write it yourselfProgramI have developed a tool for verifying the md5encryption by downloading files on the Internet. Here I will contribute the source code, and I will introduce some

Md5.digest Introduction
MD5 Algorithm (http://en.wikipedia.org/wiki/MD5) has been one of the most widely used information digest algorithm, commonly used to check errors, such as the command md5sum.
