用Java实现KeyFile

KeyFile的实现是这样

/**

* KeyFile<br/>

* Date: <br/>

* Time: ::<br/>

*

* @author vhly[FR]

*/

public class KeyFile {

/*

<KeyType type=>

<LicenseKey keyVersion=>

<ExpireDate value=/>

<EMail value=/>

<MachinelInfo value=Java/>

<UserName value=vhly FR/>

<ProductName value=Smart Development Environment Enterprise Edition for IntelliJ/>

<ProductVersion value=/>

<ProductBuild value=/>

<ProductRegisterDate value=/>

<SerialNumber value=/>

<VerifyKey value=NTQRANjE+NzxOUA/PkIzNEdBOEEPgPUBbCATUFDPzycXRWalxfXNlhiFHVpYZIEZhmdXFZtIkVeeCcHFyctLFRnhGZaJzfWsiUGlzdxfSNrfXQjVnBcydVgPDUPzEMMNUAQEQQXfQ=/>

<Evaluation value=false/>

<Type value=/>

</LicenseKey>

</KeyType>
