Encryption Anxiety

I have setup my reports to communicate with XOR encryption. The algorithm is weaker than anything I’ve worked with before. I want to find an open-source license free encryption algorithm that I may use. XOR just isn’t cutting it for me. I’ve seperated the encryption/decryption routines from my scripts so that they just use link messages to determine what they should do. This lets me swap encryption methods much quicker. I keep seeing a lot about AES, but I don’t know what the license status is. There are also limitations with LSL that I need to work around as well.
