Obfuscate AES password
The topic of this list is R, not security. For the purposes of this mailing list the user needs to take responsibility for the password. If you want to take that responsibility (cache it) from the user then you need to talk to experts on security so you can become one yourself.
IMHO obfuscating a password is worse than leaving it plain, because that would be misleading the user about how securely the password is being managed.

Hi, I need some help with obfuscating AES key on Windows, Linux and Mac. I have asked the same question on stackoverflow, but since I didn't receive any input I have decided to post it here too. You can find my question at: http://stackoverflow.com/questions/29580742/protect-aes-key-used-in-r-code The package I am writing interfaces R to various services we have available in my company and some of these require to receive username and password. I ask the credentials to the users during the installation, and save them in an encrypted using AES from the digest package and writeBin. This way users don't need to hardcode their credentials and we can share the code without issues. The problem is that the AES key is saved as plain text on the machine, so that an intruder has access to the machine he can easily decrypt the users profile and get their credentials. What is the best way to protect the key, so that even if somebody gets the encrypted file he can't decrypt it easily? Thanks a lot in advance for the help, Cheers. Luca
