Maiores Instruções

1º) Copie os 3 Scripts na Ordem

2º) É Necessário a "TCrypt.dll" para funcionar que pode ser encontrado no Anexo

3º) No Script KGC compress Save File Procure por esta linha:

Código:: CRYPT_KEY = "insertencryptionkeyhereplease"

Mude o que está entre parenteses para alguma coisa a gosto, Lembrandoque isto será como uma "Senha" que irá proteger o jogo portantocapriche porque se alguem descobrir acabou o desencrypt =/(sugiroseguir regras de segurança de criação de senhas e usar a "senha"Randomizada)

4º) no mesmo script citado acima procure isto:

Código:: ENABLE_CRYPT = true

Esta linha permite que o metodo funcione, se Colocar False ele nãoencripta o jogo(é recomendavel por False durante o periodo dedesenvolvimento do jogo para evitar problemas)

5º) NUNCA mude a CRYPT_KEY depois de criado um arquivo de save, pois irá crashear o save.

Notas e Observações

EsteMétodo Funciona tanto em RMXP quanto RMVX, Porém como todos os métodosdo mundo Não irá proteger 100% o seu projeto, mas irá dificultarmuitissimo a vida dos desencriptadores, aconselhavel e muito Usar.
