Encryption And Decryption of Json Input String with Key

[vamsi krishna]

This is my input in Android : 

{"Idno":"DK8788","Pwd":"d7877578788k","Action":"Profile"}

Encryption : s\/cBy3hAQ3bI5Ek5L+QKrK3Cy5HF8+iSsHHOV1YEcAEJLk4dQ4oYkTS1zoY\/1ZFvV7YaJzAhkZ4Q\ngkI51mJCqQ==\n

But in my code i am getting  

nr0yG3cg/+98i2JCRtj+vdKRJ71f+ItOYjYMqj07oohNATc43yOoHlJ68n8oxe6gSy/eq8z8lydkm+4cjwoNHA==

var plainText = '{"Idno":"DK8788","Pwd":"d7877578788k","Action":"Profile"}';
final key = aes.Key.fromUtf8('Al@ex%oZawyerXYx');

final iv = aes.IV.fromLength(16);

final encrypter = Encrypter(AES(key, mode: AESMode.cbc,padding: 'PKCS7'));

final encrypted = encrypter.encrypt(plainText, iv: iv);

final decrypted = encrypter.decrypt(encrypted, iv: iv);

print("Decrypt : $decrypted");

print("Encrypt : $encrypted".toString());
print(encrypted.base64);

Please Help Me I am trying last one week

Looks your function is correct. 

If your  '$decrypted' is correct with the original jsonString (plainText), your function does the correct job.

For difference with your "Android output", may due to param and/key selection.

Hi Vamsi,

I tried your codes in iOS simulator (iPadOS 14.5) and got the same results as you got, different from your Android.

May I ask what "Input in Android" means?   The same code is deployed on the Android simulator or other apps/packages?

Any other suggestions?
