Security mechanisms MAC for messages for tamper-proof The initiator first Base64 the label data, according to the encoded data, then loop xor (divide the data into several 8-byte data segments, and finally less than 8 bits plus 0x00 8-bit). Get

For example, binary string, 11111111111111 (14) converted to 16 byte (FF 3F 00 00) and 11 converted to 03 00 00 00 How to convert, do you want to use the pack function? REALISTIC Example!!! Toss two days, very urgent, ask the great God

I used Jcrop to get x, y coordinates, width, height, passed to uphoto.php processing, now everything is normal, but if the front-end user chooses the picture width is too large (I use CSS style control user selected picture maximum width is 680px),

PHP implements escape and unescape function code sharing in Javascript, and escapeunescape. PHP implements code sharing of the escape and unescape functions in Javascript. the escapeunescape class is quite useful. why? PHP transmits GBK characters

Simply talk about Unicode and UTF8 encoding in PHP, Unicodeutf8 Re-recognize Unicode and UTF8 encoding Until today, to be exact, I just knew that UTF-8 encoding and Unicode encoding are not the same, there is a difference between the

PHP implements the escape and Unescape function code sharing in JavaScript, Escapeunescape This class is pretty good. function, PHP to do JSON pass GBK characters, such as Chinese, Japanese, Korean god horse Unicode most suitable. 1) {//

Encountered a Chinese string sorting problem, to get the first letter of Chinese, the program can get the first letter of any string.The principle is that according to the gb2312 encoding is sorted by pinyin. Unfamiliar with gb2312, you can look at

$str = "This is a test program 1"; echo Getfirstcharcode ($STR); function Getfirstcharcode ($STR) { $str = Iconv ("UTF-8", "gb2312", $str); $targetChar = ' * '; $i = 0; while ($i $tmp =bin2

/** * Common symmetric encryption algorithm classes * Support key: 64/128/256 bit (byte length 8/16/32) * Support algorithm: Des/aes (based on key length automatic matching using: Des:64bit aes:128/256bit) * Support mode: CBC/ECB/

JSON does not support Chinese characters. If you use JSON to transmit Chinese data, data loss or garbled characters may occur. The strings to be sent must be encoded before transmission, in the past, JavaScript was used for data parsing. Considering

Early on, I found a reference table (gb2312.txt) for converting Gbit/s to 8 Gbit/s, and used it to output Chinese Characters in GD. When the content to be output contains Spanish characters, confusion may occur. Later I found the modified Code .

Front-end developers know that javascript has the encoding function escape () and the corresponding decoding function unescape (), while php only has urlencode and urldecode. This encoding and decoding function is effective for encodeURI and

The front-end development engineers know that JavaScript has the encoding function escape () and the corresponding decoding function unescape (), while PHP has only a urlencode and UrlDecode, This encoding and decoding function is valid for

This paper analyzes the related problems of generating random numbers for encryption. PHP 5 does not provide a simple mechanism for generating robust random numbers in cryptography, but PHP 7 solves the problem by introducing several CSPRNG
