symmetric encryption algorithms list

This article mainly introduces the example of the php symmetric encryption algorithm. For more information, see This article mainly introduces the example of the php symmetric encryption algorithm. For more information, see Php symmetric

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

Recent whim to the database to save some confidential things, and then think how to let others even into the database can not understand what is stored, then only encryption; but we have to look at it, it can only find some symmetric encryption algorithm, we want to see when the decryption back. The following is an introduction to the simple implementation of

: This article mainly introduces the php-simple symmetric encryption algorithm and the conversion function between the string and the hexadecimal system. if you are interested in the PHP Tutorial, refer to it. /** * Encryption of simple symmetric encryption

Comments: Common encryption algorithms include symmetric encryption algorithms, asymmetric encryption algorithms, and Hash algorithms.

IntroductionBecause this article is relatively simple is not an example of code implementation, on-line MD5 and encryption algorithm many can download their own research, this article is just about the differenceMD5 is an irreversible encryption, it must be remembered is irreversible although

Objective Found a good PHP symmetric encryption algorithm on the Internet, in the PHP syntax environment, there are UrlEncode and Urldecode,base64_encode and Base64_decode with the symmetric algorithm, but these self-band algorithm can not be called encryption algorithm, It can only be said to be a coding method. But

question about egg and egg. How can this problem be solved? Therefore, some operating systems have already put the certificates of some authoritative issuing authority on your computer during installation, so that the certificate format can be resolved to a certain extent: X509, PKCS certificate discard list: the most common CRL attack "man in the middle" is mainly because the identity of both parties cannot verify session hijacking, data insertion,

Common encryption algorithms include symmetric encryption algorithms, asymmetric encryption algorithms, and Hash algorithms.

In the previous section, symmetric encryption (resolution:Confidentiality of), one-way encryption (resolves:completeness), key exchange (resolution:completeness）。 But is it always possible to be disruptive by e, is there a way to resolve the identity of the other way?This time the public key encryption algorithm comes
