Netenvelop

NetEnvelop software – an Android App to encrypt/decrypt emails.
The product uses PGP protocol to make secure email communication. It creates a RSA key pair,
which contains a public key and a private key. The private key is saved in the Android device, and the
public key is uploaded to NetEnvelop key exchange server.
When user A wants to send a secure email to user B, user A launches NetEnvelop app in his/her
Android device, and NetEnvelop app retrieves user B’s public key from NetEnvelop key exchange
server, creates a random string as the session key, uses user B’s public key to encrypt the session
key, uses the session key to encrypt the email content, and send both the encrypted session key and
encrypted email content to user B.
