When you choose to attach your public key to your email, the recipient will receive it in the form of an .asc attachment.  The .asc file contains your public key information. This format will be readable by a text editor and can be used by PGP encryption software to store a contact’s public key for convenience.

You can also export your public key by going to Settings > Mail encryption > Export public key. Clicking this button will launch a popup and from there you will need to highlight all of the text and place it into a text file on your desktop.

Note: It is also possible to export your private key from within StartMail. However, you should NEVER share your private key with anyone else, as this can lead to others being able to encrypt and decrypt your email. In an .asc file, your private key is enclosed between BEGIN PGP PRIVATE KEY BLOCK and END PGP PRIVATE KEY BLOCK warnings.

The contents of an .asc file that contains only your public key will look like this:

When copying and pasting your public key, you should always include the lines that start with "-----" as they indicate where your key begins and ends.

Your key pair is a file that contains both your public and private key, which you will need if you want to use your StartMail PGP identity in another mail program (such as an IMAP client with PGP support.) It contains your public and private keys. Again, please make sure to never share your key pair with anyone else other than a trusted email client, as it includes your private key. A PGP key pair looks like this:
