DocVault is a program to let you encrypt files, add descriptive “tags” to them, and move them to a document storage location. Later on, you can search for the file by tags and select the ones to decrypt.
It currently requires a local installation of SQL server and only copies the encrypted files to a local directory. However, you can set your encrypted file location to a directory that is mirrored online, like you have with OneDrive, Dropbox, or Google Drive.
I plan to remove the local SQL server requirement in the near future.
