At both ends, we have to take same encryption and decryption algorithm. Here we are using AES(Advanced encryption standard) algorithm. When we required plain text send as encrypt text with a secret key. sometimes it becomes challenging to decrypt an encrypted text to the cross-platform environment.

We have to use the same secret in both cross-platform environments (javascript and java).

java.security.InvalidKeyException --> Illegal key size.

Repeat process until sufficient data has been generated throw new RuntimeException I hope, this will be helpful.
