Android mail pgp

Android provides built-in support for PGP (Pretty Good Privacy) encryption for email messages. Here's a step-by-step guide on how to use PGP with Android:

Prerequisites:

  1. You need to have a PGP key pair generated and shared with the recipient(s) you want to encrypt emails for.
  2. You need to have a compatible email client installed on your Android device, such as K-9 Mail, OpenKeychain, or ProtonMail.

Step 1: Generate a PGP key pair

  1. Go to a PGP key generation website, such as Keybase or GnuPG.
  2. Follow the instructions to generate a key pair. You'll need to choose a password and a name for your key.
  3. Save your private key securely, as you'll need it to decrypt emails.

Step 2: Share your PGP key

  1. Share your public key with the recipient(s) you want to encrypt emails for. You can do this by:
    • Sending them your public key as an attachment or in the body of an email.
    • Adding your public key to a public key server, such as Keybase or GnuPG.
    • Using a PGP key exchange service, such as ProtonMail.

Step 3: Configure your Android email client

  1. Open your email client and go to the settings or preferences menu.
  2. Look for the "PGP" or "OpenPGP" option and enable it.
  3. Enter your private key password and select the key you generated earlier.

Step 4: Encrypt and decrypt emails

  1. Compose a new email and select the recipient(s) you want to encrypt the email for.
  2. Tap the "PGP" or "OpenPGP" button to encrypt the email.
  3. The email client will use your private key to encrypt the email and attach your public key to the email.
  4. When the recipient receives the email, they can use their private key to decrypt the email.
