X.509 "Bad Key" error - EnvelopedCms.Decrypt()I'm trying to put together a demo for signing/verifying/encrypting/decrypting documents via pkcs #7 in VS2005, as per instructions in http://msdn2.microsoft.com/en-us/library/ms180960(en-US,VS.80).aspx The problem I'm getting is that when I call envelopedCms.Decrypt(), the operation fails with an error message "Bad Key". The code in question: static public Byte[] DecryptMsg(byte[] encodedEnvelopedCms) { EnvelopedCms envelopedCms = new EnvelopedCms(); envelopedCms.Decode(encodedEnvelopedCms); envelopedCms.Decrypt(); //Here I get the "Bad Key" exception return envelopedCms.ContentInfo.Content; } I am using homegown certificates (makecert.exe) and have added the "homegrown" CA - Root Agency that the makecert tool created to all trusted roots, etc. but to no avail. Any ideas? I'm relatively new to programming with x.509 Regards, Ziga Hello Ziga,
i have a working example of a file encryptor/signer using the X509 classes - see if that works for you http://www.leastprivilege.com/CrypterPKBeta2.aspx --------------------------------------- Dominick Baier - DevelopMentor http://www.leastprivilege.com Show quoteHide quote > Hi! > > I'm trying to put together a demo for > signing/verifying/encrypting/decrypting documents via pkcs #7 in > VS2005, as per instructions in > http://msdn2.microsoft.com/en-us/library/ms180960(en-US,VS.80).aspx > > The problem I'm getting is that when I call envelopedCms.Decrypt(), > the operation fails with an error message "Bad Key". > > The code in question: > > static public Byte[] DecryptMsg(byte[] encodedEnvelopedCms) > { > EnvelopedCms envelopedCms = new EnvelopedCms(); > envelopedCms.Decode(encodedEnvelopedCms); > envelopedCms.Decrypt(); //Here I get the "Bad Key" > exception > return envelopedCms.ContentInfo.Content; > } > I am using homegown certificates (makecert.exe) and have added the > "homegrown" CA - Root Agency that the makecert tool created > to all trusted roots, etc. but to no avail. > Any ideas?

Thanks for the sample, but I managed to get this far without a hitch. I can sign/verify, and encrypt without a problem. Where I crash is on encryptedMessage.Decrypt() where I get the infamous "Bad Key" error. The same happens with your demo, which leads me to believe it has something to do with my key settings or infrastructure. Where do you keep your keys and how do you generate them?

decrypting?!? I've been banging my head about it since yesterday afternoon. Same goes for X509ChainPolicy, which is supposedly a propert of the X509Certificate2 object -- which of course has no like property.

I generated one with Windows2003 CA, as Dominick has suggested and everything works nicely.
