Criptografia com PHP

October 18, 2010

Fala Pessoal!

O PHP permite usar criptografia[bb]de 3 formas simples, sendo que em apenas uma delas existe “volta”, ou seja, a descriptografia da string.

1 – base64

Codigica uma string com base64. Para codificar, usa-se o método base64_encode() e para decodificar usa-se base64_decode().


2 – MD5

Codifica uma string em um hash hexadecimal de 32 caracteres. Não há método para decodificação.


3 – Crypt

Retorna uma string criptografada usando o algoritmo Unix Standard DES-based. Não há método para decodificação.


Das três formas, a mais segura[bb]é MD5.

Bom, é isso.

Um abraço!
