When you received Encrypted string, i will decrypt this one to bytes.

Work Flow:

Bytes => String Encrypted …Crossing network => String => Bytes

You can use CheckSum algorithm to keep intact your data that sending cross network.

If you have any questions, let me know or comment.

It seems to encrypt and decrypt fine, however, if I encrypt to string, send the string across the network via TCP, and then attempt to decrypt it fails with “Invalid Character…” on the:
‘inputByteArray = Convert.FromBase64String(strExOTxt)’

Any idea why that is? I’ve had a search around to see if anyone has encountered this problem but not found anything. Wondering if I should get to work sending a bytearray across the network instead of the string?

The contents of strExOTxt by the way is: “uMJ+ovaul7o=” Where’s an invalid character in that!? ‘=’ is a buffer, and ‘+’ is allowed, as are the upper/lower case chars!!?

Any help muchly appreciated.
