The kConvertUserPasswords.sh script is used to convert the user password storage algorithm between a one-way hash and a reversible encryption scheme. Converting to the hashing algorithm ensures the security of your saved user passwords, but disables the [USR.PASSWORD] token in any commands, notifications, and other entities where it is used. The standard encryption option (the default) saves passwords securely encrypted with the El Gamal public/private key algorithm, which enables the server to decrypt the passwords for uses such as the [USR.PASSWORD] token.
