This is something I’ve create myself, lately, to send email through Googlemail without having the unencrypted mail stored on their servers. To accomplish this, you’ll need a Google Googlemail account, PGP or GnuPG, Mozilla Thunderbird, and the Enigmail extension.
Initially, set the Gmail bank account to allow POP3 access. This is set in the mail configurations within the web interface. The Gmail system will tell you the settings it is advisable to make in Thunderbird to be able to use this.
Following, get Thunderbird and the Enigmail extension, and install the two, along with PGP or perhaps GnuPG. After that, enter your account settings into Thunderbird, as per the Gmail account .
You’ll need to make a PGP key associated with the e-mail address. In PGP, do this making use of the GUI software. With GnuPG, type gpg -gen-key and follow the recommendations. You can establish the key type, key size (Go with at least 2048 parts. Many people use 4096) and the expiration date. Many people set the keys not to expire, I love a key duration of 6 months, so that I wrap up recreating secrets twice 12 months, but in least in the event that someone breaks or otherwise acquires my key element during that time, they will not have very long to do it, nor to use this, before that gets modified again!
Finally, associate the keypair along with your e-mail address, in the Enigmail settings inside Thunderbird, and be sure that mail defaults to signed and encrypted. Get hold of public keys from those individuals with who you wish to match privately, through adding those to your PGP or perhaps GnuPG keyring. Enigmail will encrypt email sent to the individuals, and decrypt e-mail dispatched from them to you personally. Mail to a recipient whose key you don’t have will not be protected, unless GnuPG / PGP can find an important for them on the public keyservers.
Secure e-mail prevents others reading personal communications plus the signing procedure authenticates the e-mail communication as being a person.
