Simple gpg with zip auto archiver

gpg-public-key-archiver

A small encryption project, to simplify managing files encryption with gpg.

It's purpose is to encrypt data by your public gpg key, and then archiving it to one file, without the need to decrypt it firstly with secret key.

Encrypting

Supposing you have some data in folder/ directory, and you public key with [email protected] idenity, You can simply do

zip -r folder.zip folder/
gpg -r [email protected] --encrypt folder.zip

to get 1 encrypted file folder.zip.gpg

But afterwards, there is no ability for you to decrypt it again, to add some extra file, for example.

So, assuming you have no access to your secret gpg key, this script creates a new folder, with previous folder.zip.gpg file, and your extra new_folder/ that you want to add.

result_folder/
   ├── folder.zip.gpg
   └── new_folder/

Gets to result_folder.zip.gpg

Decrypting

When you get your secret key in gpg keyring, it's time to get all files back.

Decrypting file goes the same, but in reverse order

gpg --decrypt result_folder.zip.gpg > result_folder.zip
unzip result_folder.zip

Finally, you get result_folder/

Motivation

So, that script automates such encrypting & decrypting commands
