A PowerShell module to perform symmetric AES based file encryption and decryption using a key derived from a user-provided password
The module is designed to work in Constrained PowerShell Language environments where native methods of .NET objects is forbidden. The module is therefore written in C# code and compiled
It is possible to build the module locally using the provided build.ps1 file. The script will compile the single code file into DLL and will attempt to place that in the user's PowerShell module folder within their profile, so no system-level access is required to install the module.
