ssl encryption algorithm

The encryption algorithm is as follows: Copy CodeThe code is as follows: function Encrypt ($data, $key) { $key = MD5 ($key); $x = 0; $len = strlen ($data); $l = strlen ($key); for ($i = 0; $i { if ($x = = $l) { $x = 0; } $char. = $key {$x}; $x + +; } for ($i = 0; $i { $str. = Chr (Ord ($data {$i}) + (Ord ($char {$i}))% 256); } Return Base64_encode ($STR); } The decryption

Base64 encryption algorithm C ++ code implementation, base64 encryption algorithm code The base64 encryption rules are as follows: Base64 requires that each three 8-bit bytes be converted into four 6-bit bytes (3*8 = 4*6 = 24), and then 6-bit bytes be added with two more hig

The full name of MD5 is message-digest algorithm 5,message-digest a hash transformation of a byte string (message) that transforms a byte string of any length into a long, large integer. MD5 transforms any length of "byte string" into a large integer of 128bit, and it is an irreversible string transform algorithm, in other words, even if you see the source program and the

First of all, it is said that SSH is not the three main framework of Java tradition, but a kind of security shell protocol based on application layer and transport layer, and familiar with Linux friends often use a tool of SSH Secure Shell cilent. This paper is also based on this tool encryption principle of learning, in the SSH encryption principle, the use of RSA Asymmetric

From: http://snowolf.iteye.com/blog/379860 Encryption and decryption were once an important component of my graduation project. After many years of work, it was too simple to recall the encryption and decryption algorithm at that time.To put it bluntly, here we mainly describe some encryption and decryption algorithms

With the development of symmetric cipher, the DES data Encryption Standard algorithm, because of its small key length (56 bits), has not adapted to the requirements of today's distributed open Network for data encryption security, so 1997 NIST publicly recruited new data encryption Standard, namely AES[1]. After a tric

Digital signatures are common: Before learning about digital signatures, you must first understand the SHA-1 digest and RSA encryption algorithm. Then, learn more about digital signatures.SHA-1 SHA-1 (secure hash algorithm) is Data encryption algorithm.The idea of this algorithm
