iOS AES加密 PHP解密

1.php代码

<?php  

$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);  

$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);  

$key = 'a16byteslongkey!a16byteslongkey!';  

$plaintext = "iphone";  

$ciphertext = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $plaintext, MCRYPT_MODE_ECB);  

$base64encoded_ciphertext = base64_encode($ciphertext);  

echo "ciphertext: ".$base64encoded_ciphertext."<br/>";  

$plaintext = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, base64_decode($base64encoded_ciphertext), MCRYPT_MODE_ECB);  

echo "plaintext: ".$plaintext."<br/>";  

$base64encoded_ciphertext =  "I3chV+E2XUHeLCcJAhBaJQ==";  

$plaintext = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, base64_decode($base64encoded_ciphertext), MCRYPT_MODE_ECB);  

echo "plaintext: ".trim($plaintext);  

?>   

2.oc代码

    NSString *key = @"a16byteslongkey!a16byteslongkey!";

    NSString *plaintext = @"iphone";

    NSString *ciphertext = [plaintext AES256EncryptWithKey: key];

    NSLog(@"ciphertext: %@", ciphertext);

    plaintext = [ciphertext AES256DecryptWithKey: key];

    NSLog(@"plaintext: %@", plaintext);
