[JashuVetron]

Hello,
I am convert my string to encrypted string using AES encryption that's working fine and also and decrypt that encrypted string using same IV and Salt key.
The issue is that i have one encrypted string that should be decrypt using IV and salt key but it's not
It is returning nil instead of decrypted string.

Below are my string data :
