At-Rest Encryption

  • All mail is AES-GCM-256 encrypted prior to storage, all headers included. All mail sent Codamail to Codamail is fully encrypted. Outside mail is encrypted upon receipt. Mail is only decrypted when you read it. This is all transparent to you, no matter what e-mail client you use.
  • Note: The server holds the key for this, so it isn't zero access, see Zero Access Encryption

Zero Access Encryption

  • Auto-encrypt all incoming mail with one master public PGP key or
  • Only Auto-encrypt specific aliases with their own public PGP keys or

    • An example could be a filter that auto-encrypts any mail where the subject line begins with the word Encrypt.
  • Automatic PGP encryption is not tied to your account or login password, this means you can move your email anywhere still encrypted and read it elsewhere with your private key. Even your encrypted email is not tied to this service.
  • You have full control. Your choice, your keys, your mail.

E2EE with PGP

  • Communicate with others using PGP for end-to-end encryption, which ensures that only you and who you are communicating with can read these messages.
