Problem in AES - omid_student - 04-01-2020
Hi
Why when i use below code for decryption,result is empty
PHP Code:
$this->load->library('encryption');
$this->encryption->initialize(
array(
'cipher' => 'aes-256',
'mode' => 'cbc',
'key' => 'RfUjXn2r5u8x!A%D*G-KaPdSgVkYp3s6'
)
);
echo $this->encryption->decrypt('R0gyV2NwQEJ5ZVZKODVnaHYEbS37syFYTcQNdwMXMQo=');
But when i use below code,it return correct result:
PHP Code:
function EncryptAES($message, $key){
$ivsize = openssl_cipher_iv_length('aes-256-cbc');
$iv = openssl_random_pseudo_bytes($ivsize);
$ciphertext = openssl_encrypt($message,'aes-256-cbc',$key,OPENSSL_RAW_DATA,$iv);
return $iv . $ciphertext;
}
You can decrypt it in https://www.devglan.com/online-tools/aes-encryption-decryption
Thanks
