Analysis of four basic encryption algorithms in Java and Analysis of Java encryption algorithms
Simple java encryption algorithms include:1. BASE64
Base64 is one of the most common encoding methods used to transmit 8-bit code on the network. For details, refer to RFC2045 ~ RFC2049, which has the MIME detailed specification. Base64 encoding can be used to transmit
Php mcrypt-based encryption and decryption instances and mcrypt-based encryption and decryption instances
This example describes how to implement encryption and decryption Based on mcrypt in php. Share it with you for your reference. The specific implementation method is as follows:
PHP comes with a lot of encryption m
Caesar Code
1. Introduce
Caesar cipher as one of the most ancient symmetric encryption system, in ancient Rome has been very popular, his basic idea is: by moving the letters to a certain number of digits to achieve encryption and decryption. All letters in the plaintext are replaced Cheng Mi-wen after they are offset (or forward) by a fixed number on the alphabet. For example, when the offset is 3, all t
implement the Clea method. When invoked, the clear method overwrites all sensitive data within the object with 0, and then releases the object so that it can be safely reclaimed by the garbage collector. When the object has been cleared 0 and released, the Dispose method should be called and the disposing parameter set to True to free all managed and unmanaged resources associated with the object.
2. AES Class
The AES class is an abstract class, and all implementations of the Advanced
SummaryIt is difficult to imagine users in what kind of network environment using our development of the application, if the user is in a network environment is not a trusted environment, then the user's account security may be a threat, such as the user logged on the account password submitted by the network sniffer theft, client-side encryption data can effectively defend the network sniffer to steal data , it improves the safety factor of the syste
BAT files are easy to use, but security is too fragile
Anyone can open the view or even modify the contents
Is there any way to convert. bat to. exe or. com, and so on, still. bat files
But others can't view and modify the contents of it???
Is there any kind of self encryption or something?

PHP Learning--php Encryption, PHP learning--php encryption
There are several types of encryption in PHP:
1. MD5 Encryption
String MD5 (string $str [, bool $raw _output = false])
Parameters
STR--the original string.
Raw_output--If the optional raw_output is set to TRUE, then the MD5 Digest is returned in the original b
Client hash encryption (Javascript hash encryption, with source code), javascriptSummary
It is hard to imagine the network environment in which users use the applications we developed. If the network environment in which users are located is not a trusted environment, the user's account security may be threatened, for example, when a user logs on, the account and password submitted by the user are stolen by
Objective:
These days the company temporarily pulled to do Android IM instant Messaging protocol implementation, the general view of their agreement, because the previous did not participate, is said to be due to server performance restrictions, only to achieve a non-clear delivery, specific reasons I am not clear, but the encryption used here is the use of XOR or encryption. This
Des:Digital Encryption Standard. Obsolete Standard.Single key algorithm is the sender of the information using key A for data encryption, the receiver of the information uses the same key a for data decryption. The single key algorithm is a symmetric algorithm.The algorithm is good at adding/solving speed, the key volume is short, symmetric encryption is used Dsa

Recently in the project, the issue of DES Encryption and decryption was encountered.Scene is the Android app side with Des encryption, PHP this side need to decrypt. No prior contact with Des this encryption and decryption algorithm, but think there will definitely be demo. So Baidu, search the code to use. Online code is also a mixed bag, and finally test the PH
