how can i create a certificate that allows me to sell my apps, i tried to send mine in to the android market but this message popped up… help please!

“Market does not accept apks signed with the debug certificate. Create a new certificate that is valid for at least 50 years.
Market requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate.” [import]uid: 10827 topic_id: 4971 reply_id: 304971[/import]
