Verifying signature throws "input too large for RSA cipher"
dragonk-m opened this issue · comments
I have been using xvdtool for a while and it works flawlessly, but this the first time it appears to be failing for decrypting files. I usually print package information to check I am using the right key to decrypt, and even on printing package info it fails. Debugging tells me it fails while checking for signature. Exception says "input too large for RSA cipher."
Hey, thx for the report. Could you somehow provide more metadata about the xvc container you are testing with?
Also, which RSA pubkeys are in your xvdtool folder? Please provide a file listing.
A possible workaround for the moment might be to empty out the XvdSigningKeys folder - so it does not attempt Sig verification.
Would the ContentId or ProductId for it be enough to know which package is it?
Inside the actual xvdtool folder I have no keys, under the AppData one I have the default ones
ContentId / ProductId and filename ideally would help.

Please provide the file structure of that folder.
Lastly, to make sure, we are talking about a MSIXVC, correct?
Was the problem solved?
