Hi Pete, Would it not be better to create a small Java application that takes the encrypted content and returns the decrypted content (possibly passing in a file and creating a new file with the decrypted content?).
You can also compile Java to a .Net DLL using (https://www.ikvm.net), so you can call it directly without passing files backward/forward.

In a nutshell, the application will have to be online in order to decrypt backup sets from newer UCOS versions. Last year Cisco started patching DRS with a new algorithm (PBEWithHmacSHA1AndDESede) to encrypt the random backup passwords. I haven't been able to find a .NET implementation of this algorithm. The only workaround I've come up with is to have the DRS Backup Decrypter make a call to a Java webservice that can perform the decryption. The problems with this approach are pretty obvious. Aside from having to be online, the encrypted cluster security password and 'EncryptKey' from a backup set will need to be submitted to a web service that I've written for decryption. I can publish a public copy of this webservice, but for those behind corporate proxies (myself included), the code could be made available to run the service within their own networks. In that case the DRS Backup Decrypter would be pointed to the internal copy of the webservice. I personally detest utilities that can't operate offline, but it's the only workaround I can come up with at this point. So my question is this - would anyone actually use it given the webservice dependency? _______________________________________________ cisco-voip mailing list [email protected]<mailto:[email protected]> https://puck.nether.net/mailman/listinfo/cisco-voip
