Fala galera!
Alguém ai perito em autenticação e criptografia java?
Tenho esse código aqui e queria remover a autenticação e tirar a criptografia md5, SHA1 e deixar somente o a licença sem criptografia.
Só para terem uma ideia esse codigo faz leitura do serial HD, CPU e DATA e gera uma inf.txt e esse codigo gera um arquivo god.lic.

if (cont == 1)

System.out.println("valido");
}
else if (cont == 3)
{
System.out.println("valido com failover");
}
else
{
n.geraInfo();
System.out.println("invalido");
}
}
