Informations about Private Key and Validity Handling:

The application comes without a personal key pair (the users private and public key) - so it is fully functioning in the sense of sending and receiving emails as any other mail client and provides the correct usage of validation if the mail you receive is signed by the sender.

For signing or encrypting a message it is necessary to use a private key you own. Turn to a Trust Center of your choice as a source of supply. You can find a list of trust centers, which are trusted within the Android world, in the Certificate Store (CA section) of R2Mail2. Please be aware that this app can only support Soft-Token in form of P12-files and will not work with smartcard-based certificates.
