  90 Η μαζική παρακολούθηση δεδομένων παραβιάζει τα θεμελιώδη δικαιώματα μας και κάνει την ελεύθερη έκφραση ριψοκίνδυνη.
  91 Αυτός ο οδηγός θα σε διδάξει μία βασική τεχνική αυτοάμυνας απέναντι στην παρακολούθηση: την κρυπτογράφηση του email.
  92 Όταν τον ολοκληρώσεις, θα είσαι σε θέση να στέλνεις και να λαμβάνεις μηνύματα email κρυπτογραφημένα έτσι ώστε να είσαι βέβαιος/η ότι ένας πράκτορας παρακολούθησης ή ένας κλέφτης που υποκλέπτει το email σου δε θα μπορεί να το διαβάσει. Το μόνο που χρειάζεσαι είναι ένας υπολογιστής με σύνδεση στο Διαδίκτυο, ένας λογαριασμός email και περίπου μισή ώρα. </p>
  93
  94 <p>Ακόμα και αν δεν έχεις τίποτα να κρύψεις, η χρήση της κρυπτογράφησης βοηθά ώστε να προστατευτεί η ιδιωτικότητα των ανθρώπων με τους οποίους επικοινωνείς και κάνει τη ζωή δύσκολη για τα συστήματα μαζικής παρακολούθησης.
  95 Εάν έχεις όντως κάτι να κρύψεις, τότε είσαι σε καλά χέρια: αυτά είναι τα ίδια εργαλεία που χρησιμοποίησε ο Edward Snowden ώστε να μοιραστεί τα περίφημα μυστικά του σχετικά με την NSA.</p>
  96
  97 <p>Επιπλέον της χρήσης κρυπτογράφησης, η αντιμετώπιση της παρακολούθησης απαιτεί να αγωνιστούμε πολιτικά για μια <a href="http://gnu.org/philosophy/surveillance-vs-democracy.html">μείωση της ποσότητας των δεδομένων που συλλέγονται για εμάς</a>, αλλά το απαραίτητο πρώτο βήμα είναι το να προστατέψεις τον εαυτό σου και να κάνεις την παρακολούθηση της επικοινωνίας σου όσο πιο δύσκολη γίνεται. Ας ξεκινήσουμε!</p>

 110 <p class="notes">Αυτός ο οδηγός βασίζεται σε λογισμικό με ελεύθερη άδεια χρήσης: είναι εντελώς διαφανές και ο καθένας/μία μπορεί να το αντιγράψει ή να φτιάξει μια δική του έκδοση. Αυτό το κάνει ασφαλέστερο έναντι στην παρακολούθηση από ιδιόκτητο λογισμικό (όπως είναι το Mac OS). Μάθε περισσότερα σχετικά με το ελεύθερο λογισμικό στο <a href="https://u.fsf.org/ys">fsf.org</a>.</p>
 111
 112 <p>Τα περισσότερα λειτουργικά συστήματα GNU/Linux διατίθενται με το GnuPG προεγκατεστημένο, οπότε δε χρειάζεται να το κατεβάσεις. Πριν να ρυθμίσεις το GnuPG όμως, θα χρειαστεί να εγκαταστήσεις ένα πρόγραμμα email στον υπολογιστή σου. Οι περισσότερες διανομές GNU/Linux έχουν μια ελεύθερη έκδοση του προγράμματος email Thunderbird διαθέσιμη προς εγκατάσταση.
 113 Αυτός ο οδηγός θα δουλέψει με αυτές, επιπρόσθετα με το ίδιο το Thunderbird. Τα προγράμματα email είναι ένας άλλος τρόπος πρόσβασης στους ίδιους λογαριασμούς όπου μπορείς να έχεις πρόσβαση μέσω browser (όπως του GMail), με ακόμη περισσότερες δυνατότητες.</p>
 114                         <p>Εάν ήδη έχεις ένα τέτοιο πρόγραμμα, μπορείς να προχωρήσεις στο <a href="#step-1b">Βήμα 1.Β</a>.</p>

Each is a long string of randomly generated numbers and letters that are unique to you. Your public and private keys are linked together by a special mathematical function.</p>
 190
 191 <p>Your public key isn't like a physical key, because it's stored in the open in an online directory called a keyserver. People download it and use it, along with GnuPG, to encrypt emails they send to you. You can think of the keyserver as phonebook, where people who want to send you an encrypted email look up your public key.</p>
 192
 193 <p>Your private key is more like a physical key, because you keep it to yourself (on your computer). You use GnuPG and your private key to decode encrypted emails other people send to you.</p>

 348                                                 <p>Email encryption is a powerful technology, but it has a weakness; it requires a way to verify that a person's public key is actually theirs. Otherwise, there would be no way to stop an attacker from making an email address with your friend's name, creating keys to go with it and impersonating your friend. That's why the free software programmers that developed email encryption created keysigning and the Web of Trust.</p>
 349
 350 <p>When you sign someone's key, you are publicly saying that you trust that it does belong to them and not an impostor. People who use your public key can see the number of signatures it has. Once you've used GnuPG for a long time, you may have hundreds of signatures. The Web of Trust is the constellation of all GnuPG users, connected to each other by chains of trust expressed through signatures, forming a giant network. The more signatures a key has, and the more signatures its signers' keys have, the more trustworthy that key is.</p>
 351
 352 <p>People's public keys are usually identified by their key fingerprint, which is a string of digits like DD878C06E8C2BEDDD4A440D3E573346992AB3FF7 (for Adele's key). You can see the fingerprint for your public key, and other public keys saved on your computer, by going to OpenPGP &rarr; Key Management in your email program's menu, then right clicking on the key and choosing Key Properties. It's good practice to share your fingerprint wherever you share your email address, so that so that people can double-check that they have the correct public key when they download yours from a keyserver.</p>
 353
 354 <p class="notes">You may also see public keys referred to by their key ID, which is simply the last 8 digits of the fingerprint, like 92AB3FF7 for Adele. The key ID is visible directly from the Key Management Window. This key ID is like a person's first name (it is a useful shorthand but may not be unique to a given key), whereas the fingerprint actually identifies the key uniquely without the possibility of confusion. If you only have the key ID, you can still look up the key (as well as its fingerprint), like you did in Step 3, but if multiple options appear, you'll need the fingerprint of the person to are trying to communicate to verify which one to use.</p>
