MD5 is a secure hashing algorithm, input two different plaintext will not get the same output value, according to the output value, can not get the original plaintext, that is, its process is irreversible; So to decrypt MD5 there is no ready-made
Nodejs Crypto module MD5 and HMAC encryptionIn Nodejs, you can use the Crypto module to implement a variety of encryption and decryption processing, in the Crypto module contains similar MD5 or SHA-1 these hashing algorithms, we can implement the
Script Function

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
I. Brief description
MD5: All called message digest algorithm 5 (Information digest algorithm), can be encrypted, but not decrypted, belong to one-way encryption, usually used for file verification

Currently, the MD5 password database has a huge amount of data, and most common passwords can reverse query the plaintext of the password through the MD5 Digest. To prevent internal personnel (persons who can access database or database backup files)
OrderIn the previous article, we introduced the most basic coding method--base64, and also briefly mentioned the principle of coding. This article continues to decrypt the series, of course, is also the introduction of a comparative basis of the
