Security sr CS
ASF currently supports 4 types of passwords - PlainText, AES, ProtectedDataForCurrentUser and None (null / "").
In order to use encrypted password, you should firstly log in to Steam as usual with PlainText, then generate encrypted passwords using password command. Pick the encryption method you like, then put the encrypted password you got as SteamPassword bot config property, and finally don't forget to change PasswordFormat to the one that matches your chosen encryption method.
This is the most simple and insecure way of storing the password, defined as PasswordFormat of ``. ASF expects SteamPassword property to be a plain text - password being used to log in to Steam in its direct form. It's the easiest one to use, and 100% compatible with all setups, therefore it's default.
Considered secure by today standards, AES way of storing the password is defined as PasswordFormat of 1. ASF expects SteamPassword property to be a base64-encoded sequence of characters resulting in AES-encrypted byte array after translation, which then should be decrypted using included initialization vector and ASF encryption key.
The method above guarantees security as long as attacker doesn't know built-in ASF encryption key which is being used for decryption as well as encryption of passwords. ASF allows you to specify key via --cryptkey command-line argument, which you should use for maximum security. If you decide to omit it, ASF will use its own key which is known and hardcoded into the application, meaning anybody can reverse the ASF encryption and get decrypted password. It still requires some effort and is not that easy to do, but possible, that's why you should almost always use AES encryption with your own --cryptkey which is kept in secret. AES method used in ASF provides security that should be satisfying and it's a balance between simplicity of PlainText and complexity of ProtectedDataForCurrentUser, but it's highly recommended to use it with custom --cryptkey.
Currently the most secure way of storing the password that ASF offers, and much safer than AES method explained above, is defined as PasswordFormat of 2. The major advantage of this method is at the same time the major disadvantage - instead of using encryption key (like in AES), data is encrypted using login credentials of currently logged in user, which means that it's possible to decrypt the data only on the machine it was encrypted on, and in addition to that, only by the user who issued the encryption. This ensures that even if you send your entire Bot.json to somebody else, he will not be able to decrypt the password without access to your PC. This is excellent security measure, but at the same time has major disadvantage of being least compatible, as the password encrypted using this method will be incompatible with any other user as well as machine - including your own if you decide to e.g. reinstall your operating system. Still, it's one of the best methods of storing passwords, and if you're worried about security of PlainText, and don't want to put password each time with None option, then this is your best bet as long as you don't have to access your configs from any other machine than your own.
Please note that this option is available only for machines running Windows OS.
The only way that guarantees 100% security and ensures that nobody can steal your Steam password. In order to use this option simply set your SteamPassword to empty string ("") or null value. ASF will ask you for your Steam password when it's required, and won't save it anywhere but keep in memory of currently running process, until you close it. While being the most secure method of dealing with passwords, it's also the most troublesome as you need to enter your password manually on each ASF run (when it's required). If that's not a problem for you, this is your best bet security-wise.
If compatibility is not an issue for you, and you're fine with the way how ProtectedDataForCurrentUser method works, it is the recommended option of storing the password in ASF, as it provides the best security. AES method is a good choice for people who still want to make use of their configs on any machine they want, while PlainText is the most simple way of storing the password, if you don't mind that anybody can look into JSON configuration file for it.
Please keep in mind that all of those 3 methods are considered insecure if attacker has access to your PC. ASF must be able to decrypt the encrypted password, and if the program running on your machine is capable of doing that, then any other program running on the same machine will be capable of doing so, too. ProtectedDataForCurrentUser is the most secure variant as even other user using the same PC will not be able to decrypt it, but it's still possible to decrypt the data if somebody is able to steal your login credentials and machine info in addition to ASF config file.
For people launching ASF rarily or those who are not bothered with entering the password on each ASF startup, None way is the most secure as Steam password is not saved anywhere.
ASF doesn't support any way of decrypting already encrypted passwords, as decryption methods are used only internally for accessing the data inside the process. If you want to revert encryption procedure e.g. for moving ASF to other machine when using ProtectedDataForCurrentUser, then simply switch your PasswordFormat back to `` (PlainText), and fill SteamPassword appropriately. You can then launch ASF as usual, and repeat the procedure from beginning.
