pbgopy v0.3.0 is here!! 🎉

It's a feature-packed release with tons of features for secure use.

Hybrid cryptosystem is now available (#25)

pbgopy comes with a built-in end-to-end encryption feature. You can now encrypt with not only the symmetric-key but also your public/private key. If you have already exchanged public keys between devices you want to share data with, this is the way to go.

You can simply encrypt/decrypt by specifying the key file:

pbgopy copy --public-key-file /path/to/public.key <plaintext.txt

pbgopy paste --private-key-file /path/to/private.key <plaintext.txt

Note that you can only use an RSA key in PEM or DER format.

Specify public/private key via GPG (#27)

You manage your keyring in GPG? The --gpg-user-id (-u) flag is for you! Suppose you want to encrypt with a public key whose user id is alice:

pbgopy copy -u alice <plaintext.txt

Then you decrypt it with the private key by specifying the user id on another device:

pbgopy paste -u alice

There are a couple of ways to specify a user ID. Visit here to see the entire list.

Existing symmetric-keys are now available (#23)

As in the past, you can derive the key from password with the -p flag, which is provided so that you can encrypt/decrypt without previous setting, while this way cannot prevent a dictionary attack. For more safety, it is highly recommended to use a 32-bytes symmetric key generated by other methods. The -k flag or the PBGOPY_SYMMETRIC_KEY_FILE environment variable is available to indicate the path to the key file.

pbgopy copy -k /path/to/pbgopy.key <plaintext.txt

Performance improvements

• Reduced unnecessary communication when deriving the key from the password (#28)

Breaking changes

• The PBGOPY_PASSWORD_FILE environment variable has been unavailable.
• The interface between pbgopy server and client has been slightly changed, hence you will need to update the binaries on all devices to use this version.
