Endpoint Encryption

I have a customer who sent me their new Key. I was able to import it into PGP Desktop sign and validate it but when I wen to use the key to encrypt a file it was not showing as an available key to use. I noticed that their new key had cipher and hash values set to none. Does PGP Desktop not support or recognize keys with this value?

Key properties may not be set properly.  Can you send me a private message with the key block for that public key?  I can load it up and see if I can spot anything specific wrong with it.  Not having any ciphers allowed would make the key unusable for encryption.  Do you know how they generated the key?

I was able to import the key and successfully encrypt a file with it.  It isn't that the ciphers are missing, it is just that there are no preferred ciphers set, so it should still be able to use the standard ciphers and hashes in the version for which it was created (in this case it looks like PGP 9.10).  I was originally concerned it might be an old enough version that the ciphers and hashes available might not be supported in newer clients.

Make sure you do the following in PGP Desktop:
Right-click the key and select "Sign...", and sign the key with your key to verify it.
Right-click the key and go to Key Properties.  Set the Trust value to Trusted.  Make sure the Enabled value is set to Yes.

It should work if you do those things.  The key usage is set for all PGP encryption types (NetShare, Disk Encryption, PGP Zip, and PGP Messaging).
 

Thanks. I removed the key and re-imported it and followed thoes steps. I am still unable to choose the key to use to encrypt the file with. 

What does it do if you select "Add 'FileName' to new PGP Zip" instead of "Secure with Key"?

Since the key information is showing as 'not licensed for commercial use', you are most likely using an unlicensed version of the software, in which case NetShare may be disabled or have other issues.  See if PGP Zip will allow you to use the key.

Also, if it is a single file, and you are selecting Secure with Key, there may be some issues with Advanced User Mode not being turned on.  It is required to use Secure with Key (which as I mentioned calls the NetShare driver) for an individual file.  Open PGP Desktop and go to Tools>Options.  Select the NetShare tab.  Check the box next to "Protect Individual Files".
