At-Rest Encryption
  • All mail is individually encrypted using elliptic-curve AES-GCM-256 prior to storage, all headers included. All mail sent Codamail to Codamail is fully encrypted, the same elliptic-curve AES-GCM-256, including all headers. 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 this type of encryption isn't zero access, even though some services claim it as such. See Zero Access Encryption below for true Zero Access.
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
  • Auto-encrypt with a filter action based on anything in the message with your choice of PGP key
    • 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. You create the key, you own the key, you control the key. 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, as easily exportable as the rest.
  • You have full control. Your choice, your keys, your mail.
E2EE with PGP
