从下载AES库
在不同平台进行AES加密，并使用Base64进行编码，结果有可能不同，但解密之后会一样，所以不要因为在2个平台加密结果不一样而认为自己错了。。。
php加密解密：
"; $plaintext = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, base64_decode($base64encoded_ciphertext), MCRYPT_MODE_ECB);echo "plaintext: ".$plaintext.""; $base64encoded_ciphertext = "I3chV+E2XUHeLCcJAhBaJQ==";$plaintext = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, base64_decode($base64encoded_ciphertext), MCRYPT_MODE_ECB);echo "plaintext: ".trim($plaintext);?>
iphone加密解密
#import "NSString+AESCrypt.h"NSString *key = @"a16byteslongkey!a16byteslongkey!";NSString *plaintext = @"iphone";NSString *ciphertext = [plaintext AES256EncryptWithKey: key];NSLog(@"ciphertext: %@", ciphertext);plaintext = [ciphertext AES256DecryptWithKey: key];NSLog(@"plaintext: %@", plaintext);
