Abstract
Encryption of message content of an e-mail sent by way of a webmail service may be performed in response to activation of a user interface element. The message content may be encrypted using a symmetric key. A public key of a recipient of the e-mail is received from a backend service and employed to encrypt the symmetric key. The encrypted symmetric key and encrypted message content are sent to a recipient by way of the webmail service. Decryption of the encrypted message content may be performed in response to activation of another user interface element. A private key of the recipient is received from the backend service and employed to decrypt the encrypted symmetric key. The symmetric key is thereafter employed to decrypt the encrypted message content.
