I'm looking to encrypt (rename) mutiple files name based on a passphrase. Currently the passphrase would be numeric but I can change that to something else if required.
I would like to be able to get a encrypted file name in numeric and/or letter (avoid any special char since they are not allowed in filename) and to be able to decrypt the file name using a passphrase.
Is it possible to encrypt the filename with a function (I'm using C#) that would not allow a hacker to reverse engineer the function and then be able to decrypt the filename. Like a one way encryption but with the possibility for me to use a different decryption function on my own system to decrypt the filename.
Thanks for your ideas!
