Suggestions

Thank you for a nice tool. Here are some improvements that will be welcome:

• Autodetect the engine version if the token has enough permissions
• Re-use the vault cli token ~/.vault-token if present and valid
• Implement more user-friendly encryption that does not require openssl but instead relies on a key derivation function
• in addittion to -insecure option allows to supply your own CA for validation
• If we gone as far as creating the delete command adding a move/copy now sounds logical
• Support also deleting single secret with delete it feels strange that it works alright on a "folder" but fails on a single secret
• Support cross-engine workflows better: have an option to include the engine name in the export/import format instead of requiring it to be present on command line only
• Add an option to display the program's version
