lucubrate of how to decipher forgotten languages are given, with examples including Egyptian hieroglyphics and the Ro batchta stone.

The work of Rivest, Sh! amir, and Adleman (RSA) combined with that of Diffie and Hellman pull round produced the first common public-key system. For the first time, the secure key swapping shake up had been truly solved. The Internet age brought the issue of security and backstair to the masses.
