Introduction: QCA: QT cryptographic architecture is a very good class library for encryption and decryption on the qt platform. However, there are still few documents and blogs about QCA in China, if you are not familiar with QT and Unix development, you may encounter some problems when using this open-source class library (as you know, there are still many problems with version matching and bug control of open-source products among different class li

Encrypted decryption function in PHP and DES encryption and decryption instance Examples, examples of PHP encryption and decryption Cryptographic functions: The code is as follows:/* * Function: Encrypt string processing * Parameter one: Content that needs to be encrypted * Parameter two: key */ function Passport_encrypt ($STR, $key) {//encryption function Srand (Double) microtime () * 1000000); $encrypt _key=md5 (rand (0, 32000)); $ctr = 0; $tmp =

encryption is that the decryption speed is much slower than symmetric encryption, and in some extreme cases, it can be even 1000 times times slower than asymmetric encryption.Common Asymmetric encryption algorithms: RSA, ECC (for mobile devices), Diffie-hellman, El Gamal, DSA (for digital signatures)Hash algorithmThe special place of hash algorithm is that it is a one-way algorithm, the user can use the hash algorithm to generate a specific length of the unique hash value of the target informat

PHP Cryptographic decryption function sharing, one is discuz! authcode cryptographic function (with detailed decomposition), one is the Encrypt () function.Need to use PHP to encrypt specific information, that is, through the encryption algorithm to generate an encrypted string, the encrypted string can be decrypted by the decryption algorithm, to facilitate the program to the decrypted information processi

The principle of 1.RSA encryption and decryption mechanism RSA public Key cryptography consists of the following 3 algorithms: KeyGen (Key generation algorithm), Encrypt (cryptographic algorithm), and decrypt (decryption algorithm). Details are as follows: So, as we can see from the algorithm description: The public key is used to encrypt the data, and the private key is used to decrypt the data . Of course, this can also be very intuitive to underst

core of many cryptographic protocols.Symmetric encryption typically uses a relatively small key, typically less than the size of a bit. The greater the key, the stronger the encryption, but the slower the encryption and decryption process. If you use only 1 bit to do this key, the hacker can first try to decrypt with the word, no, then use 1 solution, but if your key is 1 MB large, hackers may never crack, but the encryption and decryption process ta
