Encrypting and Sending
Compose encrypted emails and sign messages to prove authenticity.
← Back to the GuideBefore you start
You’ll need:
- The recipient’s public key imported into iPGMail (Find keys →)
- Your private key if you want to sign messages
- (Optional) A configured SMTP server for sending directly from iPGMail
Compose an encrypted message
- Open iPGMail → Compose tab
- Tap To: and select one or more recipients from your public keys
- Enter a Subject
- Write your message
- Optionally attach files using the attach button
- Tap Send
If you haven’t configured SMTP, iPGMail opens the Mail app with your encrypted message ready to send.
Note: Email subjects are not encrypted. Keep subject lines generic if privacy is important.
Sign, encrypt, or both
Use the mode selector to choose your security level:
Set your default in Settings → Default Mode.
Send to multiple recipients
Tap additional contacts in the To: field to add them.
The message is encrypted separately for each recipient’s key — each person can only decrypt with their own private key. No recipient can read anyone else’s copy.
Attach files
- Tap the attach button in the compose screen
- Select photos from your camera roll, or files from the Files app
- Attachments are encrypted along with your message
Tip: Large attachments may take longer to encrypt. For files over 10MB, consider using a secure file-sharing service instead.
