Md5 ciphertext cracking (decryption) is an indispensable part of network attacks and an important "auxiliary tool" in hacking tools ". Md5 decryption is mainly used for network attacks. During the website intrusion process, attackers may obtain the
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
Objective:Whether the password is stored in the project or whether the file is the same file, will use the MD5 algorithm, today to summarize the MD5 encryption algorithm.What is MD5 encryption?MD5 English full name "Message-digest algorithm 5",
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
BASE64: The 8-bit byte of any sequence is
Conversion | algorithm
MD5 is the most commonly used cryptographic encryption algorithm in Web applications. Since the MD5 is irreversible, the ciphertext after MD5 calculation can not get the original text through the reverse algorithm.
The
There are md5.c and md5.h online, but there are only MD5Init (), MD5Update (), and MD5Final () functions,
Only the characters can be operated directly, but there is no interface for directly obtaining file md5. The following is my implementation,
