PHP5.6 与 PHP7 加解密区别
PHP5.6
<?php
class Prpcrypt
{
public $key;
function __construct($k)
{
$this->key = base64_decode($k . "=");
}
public function encrypt($text)

//加密
$encrypted = mcrypt_generic($module, $text);
mcrypt_generic_deinit($module);
mcrypt_module_close($module);
//print(base64_encode($encrypted));
//使用BASE64对加密后的字符串进行编码
return base64_encode($encrypted);
} catch (Exception $e) {

PHP7 加解密方法
<?php
class Prpcrypt
{
public $key;
function __construct($k)
{
$this->key = base64_decode($k . "=");
}
public function encrypt($text)
{
try {
$iv = substr($this->key, 0, 16);
$encrypted = openssl_encrypt($text, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA, $iv);
} catch (Exception $e) {
print $e;
return false;
}
// openssl_decrypt(base64_decode($encrypted), 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA, $iv);
var_dump(base64_encode($encrypted));
return base64_encode($encrypted);
}
public function decrypt($encrypted)
{
try {
$ciphertext_dec = base64_decode($encrypted);
$iv = substr($this->key, 0, 16);
$decrypted = openssl_decrypt($ciphertext_dec, 'AES-256-CBC', $this->key, OPENSSL_RAW_DATA,$iv);
} catch (Exception $e) {
return false;
}
return $decrypted;
}
function getRandomStr()
{
$str = "";
$str_pol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";
$max = strlen($str_pol) - 1;
for ($i = 0; $i < 16; $i++) {
$str .= $str_pol[mt_rand(0, $max)];
}
return $str;
}
}
$k = "abc1237890123456789012345678901234567890abc";
$decrypStr = "hello";
$cryptObj = new Prpcrypt($k);
$ret = $cryptObj->encrypt($decrypStr);
echo $ret . "\n....";
