PHP DES加密/解密 ECB 、pkcs5/pkcs7

加密方式与http://tool.chacuo.net/cryptdes加密方式一样

<?php

echo "<br/><br/><br/>";

$key = "1234";
$jiami = encrypt("123",$key);

echo $jiami."<br/>";
echo decrypt($jiami,$key);

//加密
function encrypt($str, $key){
    $block = mcrypt_get_block_size("des", "ecb");
    $pad = $block - (strlen($str) % $block);
    $str .= str_repeat(chr($pad), $pad);
    return base64_encode(mcrypt_encrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB) );
}  
//解密
function decrypt($sStr, $sKey) {  
        $decrypted= mcrypt_decrypt(  
        MCRYPT_DES,  
        $sKey,  
        base64_decode($sStr),  
        MCRYPT_MODE_ECB  
    );  
   
    $dec_s = strlen($decrypted);  
    $padding = ord($decrypted[$dec_s-1]);  
    $decrypted = substr($decrypted, 0, -$padding);  
    return $decrypted;  
}
