About the Book
Την στιγμή που διαβάζετε αυτές τις γραμμές, μπορείτε να αισθανθείτε ασφαλείς διότι κανένας δεν μπορεί να παρεισφρήσει στην σύνδεσή σας και να δει τι διαβάζετε. Αυτό έχει επιτευχθεί διότι η σύνδεσή σας με το παρόν σύνδεσμο είναι κρυπτογραφημένη. Αυτό μπορείτε να το διαπιστώσετε κάνοντας απλά κλικ στο κλειδάκι επάνω αριστερά, στο πεδίο διευθύνσεων.
Γιατί όμως έχει σημασία αυτό;
Τι μας νοιάζει αν πρέπει να είναι κρυπτογραφημένα τα δεδομένα που φεύγουν από τον υπολογιστή μας για να έρθουν στον απομακρυσμένο αυτό διακομιστή και να μας παρουσιαστεί στην οθόνη του υπολογιστή μας αυτή σελίδα;
Γιατί ακούμε όλο και ποιο συχνά, για ασφάλεια δεδομένων, επικοινωνίας άλλα και προσπάθεια καταπάτησης των δικαιωμάτων μας στην ανωνυμία;
Πίσω απο όλα αυτά τα ερωτήματα είναι το βασικό δικαίωμα στην ελευθερία λόγου και έκφρασης και ασφαλής διακίνησης της πληροφορίας. Οι απλοί πολίτες εξασφάλισαν αυτό το αγαθό τους μετά από αιώνες αγώνων και θυσιών, ενώ ταυτόχρονα σε πολλά μέρη του πλανήτη μας εν έτη 2015, ακόμα δεν έχει εδραιωθεί η πεποίθηση ότι θα πρέπει να μπορώ να σκέφτομαι και να εκφράζομαι ελεύθερα ανεξαρτήτως μορφωτικών, φυλετικών, θρησκευτικών, πολιτικών κ.α. επιθέσεων μου εντός μιας κοινωνίας.
Στην ψηφιακή εποχή που διανύουμε, δυστυχώς πλησιάζει η εποχή που ακόμα και οι κοινωνίες που εξασφάλισαν την ελευθερία λογού θα χρειαστεί να δώσουν πάλι αγώνες για να εξασφαλίσουν το δικαίωμα να επικοινωνούν και να ανταλλάσσουν δεδομένα τα οποία θα είναι κρυπτογραφημένα.
Δεν μπορείς να αμυνθείς. Δεν μπορείς να αποτρέψεις. Το μόνο που μπορείς να κάνεις είναι να ανιχνεύσεις και να ανταποκριθείς.
-- Bruce Schneier, Guru ψηφιακής ασφάλειας και κρυπτογραφίας : https://goo.gl/wT1U0G
Το εγχειρίδιο αυτό συντάχθηκε με σκοπό να δώσει άμεσα και γρήγορα στον αναγνώστη, χωρίς τεχνικές και επιστημονικές λεπτομέρειες, όλα τα απαραίτητα εργαλεία και τις γνώσεις για να εντάξει άμεσα, την κρυπτογραφία στην καθημερινότητά του, όταν χρησιμοποιεί ηλεκτρονικές συσκευές για να επικοινωνεί με φίλους και γνωστούς του.
Εάν παρόλα αυτά, δεν έχει πετύχει τον στόχο του... τότε κάτι έχω κάνει λάθος και θέλω να μου το πείτε.
