I dreamed of a method to enhance MD5 verification. Woke up and tested it.
Everyone on Earth knows that MD5 has been broken by Wang Xiaoyun !!! Broken !!! Broken !!! Broken !!! Break ~~ (Shut
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
Comments: For a long time, MD5 encryption and verification are very secure. Many forums and software Save the password of the user name after MD5 encryption. Compared with the previous plaintext storage, the stored information after MD5 encryption
Users who often download software will find that many Download Software websites provide MD5 values. The MD5 value verification code is also provided for the 1 of the different dimensions. So what is the MD5 value? The entire process of MD5 is
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
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:
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)
IOS MD5 encryption and iosmd5 Encryption
1. MD5 Encryption
Message Digest Algorithm MD5 (the fifth version of the Message Digest Algorithm in Chinese) is a hash function widely used in the computer security field to provide Message integrity
