Public-key cryptography, or asymmetric cryptography, is a cryptographic system that uses pairs of keys: public keys, which may be disseminated widely, and private keys, which are known only to the owner. The generation of such keys depends on cryptographic algorithms based on mathematical problems to produce one-way functions. Definition: Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa.

A cromatografia em coluna é a mais antiga técnica cromatográfica. É uma técnica para separação de componentes entre duas fases, sólida e líquida, baseada na capacidade de adsorção e solubilidade.. O processo ocorre em uma coluna de vidro ou metal, geralmente, com uma torneira na parte inferior. A Criptografia reforça a segurança de uma mensagem ou arquivo embaralhando o conteúdo.

Vývoj kryptografie. Zmínky o utajování obsahu písma se objevovaly již ve starém Egyptě, Mezopotámii a Indii. Staří Řekové vynalezli nejen mechanické ukrytí utajovaných zpráv (např. překrytí zprávy vyryté do dřevěné destičky voskem), ale v 5. století př. n. l. i první jednoduché šifrové systémy.
