With Mailo, you can choose for each e-mail you send whether you want to encrypt and/or sign it with PGP.
In order to use PGP when sending an e-mail, you only have to set the PGP encryption option when writing the e-mail.
Using PGP allows:
- the encryption of the message
Encrypting a message ensures the sender that only the recipients will be able to decrypt and thus read the message.
Encrypting a message requires that the sender has the public PGP key of each of the recipients of the message.
In order to decrypt and read the message, each recipient uses their own private PGP key.
- the signature of the message
Signing a message ensures the identity of the sender to the recipients.
Signing a message requires that the sender uses their private PGP key.
To validate the signature of the message, the recipients must have the public key of the sender, who must have sent it beforehand.
Every time you send an e-mail, you can add your own public key. It is important that your correspondents have your public key, because they need this key in order to encrypt the e-mails they send you. Your public key also ensures your correspondents that you have really signed the PGP message.
