Lost Private Key

Created: 30 Jun 2011 | 6 comments

We have moved a computer at work, which has PGP Desktop 9.5 on it and since the move we are unable to decrypt the emails, is PGP IP specific? We can see keys on the computers Hard drive that appear to be the Public and Private Keys, though these files won't import. The message that comes up when we try and open a encrypted e-mail is: "It is not possible to decrypt this message because your keyring does not contain usable private key(s) corresponding to the above public key(s)." Any ideas how the Private key has vanished? or how to re-import this private key?

Regards

Keys are not IP specific.  You may want to right click on All Keys in the PGP module on the left hand side of PGP Desktop, select Properties, and make sure the correct keyrings are set.  You may then check your key listing in My Private Keys to make sure your key is there.  If it is, right click on it, select Properties, and make sure Trust is set as Implicit. 

If this doesn't do it, either set your keyrings to whatever location you have for other keyrings that may contain the necessary private key.  Or going back to All Keys, you can use the File menu to select Import to import from other private keyrings, but any imported private keys will need to have Trust set to Implicit (as above).

If none of this helps, please state how you are trying to Import the private key, and what actually happens.

We only seem to have public keys, what file extention does a private key have? What should the trust levels be set to for the public keys? If the private key is completely lost, is there is anyway of getting a new one that will open emails encrypted with the older key?

Hi,

Decrypting a file *dat.pgp, but the output of the file comes out as a txt file.  If we use the older version of PGP Desktop, the outcomes is correct *.dat file.   How can we fix this?

You might try decrypting both from the right click context menu, and from within the PGP Desktop menu, to see if either will produce your desired result.
