This article mainly introduces the php symmetric encryption algorithm example. if you need a friend, refer to the php symmetric encryption algorithm. KEY is a previously defined constant. The code is as follows: Mcrypt: encrypt ();Mcrypt: decrypt (); The code is as follows: Defined ('root') or exit ('Access Denied
Information security is more and more important today, the system design and development process of the necessary encryption technology is essential, based on the actual experience of the project to summarize the actual project in the safe use scenario.The system internal password uses MD5 encryption, the password is not reversible, cannot use any means to let anyone obtain the user's password, if the secur

The last blog about how to play the hash algorithm, but that article did not explain clearly. This blog post I will try to make the things that are not explained clearly. Of course, the theme of this article is to play symmetric encryption. . NET of symmetric encryption technology There are mainly such several: Des,aes

Q: How is 3DES symmetric encryption implemented in the S/MIME protocol? A:In fact, the 3DES encryption algorithm is part of the original S/MIME protocol. 3DES, also known as Triple DES, or Triple Data Encryption Standard, was developed by the IBM team in 1974 Based on the DES algo

Objective: For the SHA Safe hashing algorithm, before how to use, just stay in the heard of the stage, today in the picture Caching framework Glide source code found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption
RC4 in 1987, like the DES algorithm, is a symmetric encryption algorithm, which means that the key used is a single key (or a private key). However, unlike DES, RC4 does not group the plaintext, but instead encrypts each byte of the plaintext in the same way, and decrypts every byte in the ciphertext in turn.RC4 algorithm
