Odat\u0103 ce s-au schimbat chei secrete, se pot transmite mesaje cu un volum total egal cu lungimea acestora.

Cu toate acestea, aceste persoane uit\u0103 de progres, iar dac\u0103 \u00een timpul R\u0103zboiului Rece acest lucru era o problem\u0103, ast\u0103zi nu mai este.

G\u0103sirea unui server SOCKS5 public pentru o sesiune scurt\u0103 nu este dificil\u0103, iar configurarea unui astfel de server pe VPS-ul propriu este chiar mai simpl\u0103.<\/p>\n<p><\/p>\n<p>De\u0219i lovitura asupra ecosistemului serviciului de mesagerie se va produce, deoarece pentru majoritatea utilizatorilor aceste restric\u021bii vor crea \u00een continuare o barier\u0103 insurmontabil\u0103, iar popularitatea sa \u00een r\u00e2ndul popula\u021biei va avea de suferit.<\/p>\n<p><\/p>\n<p>A\u0219adar, s\u0103 tragem concluziile. Toat\u0103 agita\u021bia din jurul Telegram este doar o hype \u0219i nu mai mult. Blocarea sa din motive de siguran\u021b\u0103 public\u0103 este tehnic analfabet\u0103 \u0219i lipsit\u0103 de sens. Orice structuri care au un interes vital \u00een comunica\u021bii securizate pot organiza propriul canal, folosind mai multe tehnici complementare, \u0219i, ceea ce este cel mai interesant, acest lucru se face extrem de simplu, at\u00e2t timp c\u00e2t exist\u0103 o oarecare conexiune la re\u021bea. <\/p>\n<p><\/p>\n<p>Frontul securit\u0103\u021bii informa\u021biei ast\u0103zi se desf\u0103\u0219oar\u0103 nu prin servicii de mesagerie, ci mai degrab\u0103 prin utilizatorii obi\u0219nui\u021bi ai re\u021belei, chiar dac\u0103 ace\u0219tia nu con\u0219tientizeaz\u0103 acest lucru.

Blocarea Telegram este un alt exemplu de r\u0103zboi pentru pia\u021ba informa\u021bional\u0103.

De aceea, blocarea adreselor IP nu ar trebui considerat\u0103 o solu\u021bie acceptabil\u0103 \u0219i demonstreaz\u0103 doar lipsa de competen\u021b\u0103 a persoanelor care iau aceste decizii.<\/p>\n<p><\/p>\n<p>Principala problem\u0103 a prezentului nu este p\u0103strarea sau analiza datelor personale de coresponden\u021b\u0103 de c\u0103tre ter\u021be p\u0103r\u021bi (aceasta este o realitate obiectiv\u0103 \u00een care tr\u0103im ast\u0103zi), ci faptul c\u0103 oamenii sunt preg\u0103ti\u021bi s\u0103 ofere aceste date de bun\u0103voie.
