[Proposal] Adding File Encryption Feature

[maksim-romanov]

Hello and thanks for your hard work!

I'd like to suggest adding a keys file encryption feature to enhance secure storage in the repository. This could prove highly beneficial for development purposes.

In our Rails projects, we've found a similar encryption approach quite valuable, and it seems to be a missing piece in your library.

As an example of file encryption, I can point to the senv library which we are using with react-native-config library

Thank you for considering this enhancement!
