Recommended Posts

http://java.sun.com/javase/6/docs/api/java/util/zip/CRC32.html O java tem uma API para CRC

Basta leres o Stream do ficheiro e enviar para o update do CRC depois de teres todo o ficheiro lido basta fazer getValue ao CRC ele retorna o numero para validar o ficheiro.

Depois é juntar o numero ao ficheiro.

I haven’t lost my mind; it’s backed up on DVD somewhere!
