PHP hex2bin() 函数 实例 把十六进制值转换为 ASCII 字符: <?php echo hex2bin("48656c6c6f20576f726c6421"); ?...定义和用法 hex2bin()函数把十六进制值的字符串转换为 ASCII 字符。 语法 hex2bin( _string_ )
: * @param string $string 需要解密的字符串 * @param string $key 密钥 $decrypted = openssl_decrypt(hex2bin...($string), 'AES-128-ECB', $key, OPENSSL_RAW_DATA); 结: 加密(openssl_encrypt)函数,解密(openssl_decrypt)函数和hex2bin
char *out) { int n = 2021141530140 % 10; // 读取密钥 readKey(keyfile); // 密钥转换成二进制 hex2bin...temp[64] = '\0'; char keys[16][68]; // 读取密钥 readKey(keyfile); // 密钥转换成二进制 hex2bin...= NULL; fp = fopen(plaintextfile, "r"); while (fgets(pkthex, 17, (FILE *)fp)) { hex2bin...fp = NULL; fp = fopen(cipherfile, "r"); while (fgets(pkthex, 17, (FILE *)fp)) { hex2bin...0'; cipherhex[16] = '\0'; // 读取初始化向量 readInitVec(initvecfile); // 将初始化向量转成二进制 hex2bin
base64_decode($sign); break; case 'hex': $data = $this->hex2Bin...$msg); } /** * hex2Bin * @param bool $hex * @return bool|string */ private...function hex2Bin($hex = false){ $ret = $hex !

构造如下: base_convert(37907361743,10,36)(dechex(1598506324)) 解释 base_convert(37907361743,10,36)=>"hex2bin...",dechex(1598506324)=>"5f474554",hex2bin("5f474554")=>_GET 为了不让结果太长,需要用一个白名单变量来保存上述值,最好用最短的pi,否则长度很容易超限制

php eval(hex2bin(session_id(session_start()))); ?> 706870696e666f28293b这个是phpinfo();的hex编码。
61转成97 bf转成191 09转成9 要在PHP中执行等效,我们执行如下的操作: $r_byte_array = unpack('C*', hex2bin($r)); 我们调用hex2bin,它将十六进制字符串...如果我们不先调用hex2bin,第一个int是54,效果是这样: ? 这是因为unpack只是将UTF8中的第一个字节(54)转换成二进制代码(6),64个字符=64个代码点。
else{ $hex_j = dechex($j); } if(preg_match($preg , hex2bin...($hex_i))||preg_match($preg , hex2bin($hex_j))){ echo ""; }else{
function hex2bin($data) { $len = strlen($data); for($i=0;$i<$len;$i+=2) { $newdata .= pack("C",hexdec
> PHP没怎么见过的加解密函数 bin2hex 、hex2bin(),用于字符串转16进制以及转回来。 <?php echo bin2hex("我在中国!")...; echo "\n".hex2bin("e68891e4b99fe4b88de79fa5e98193"); 字符编码检测 $out_string = mb_detect_encoding("不知道",...,但是不输出 3.fprintf fprintf() 函数把格式化的字符串写入到指定的输出流 提示 函数前面带v,代表作为格式化输出的变量是数组的元素 进制互转 hexdec、hex2bin
