You have the public key there. It is in PEM-encoded DER format. You did not use the public key to generate the CSR. You included the public key in the CSR, but you used that public key's private key to generate the CSR.
If you have lost that *private* key, your public key is worthless. Note that the signed certificate you have also contains the public key. If you have lost the private key, that certificate cannot be used to authenticate, because the private key that belongs to that public key must be used in a mathematical equation that's very difficult to solve without its companion key during the process of authentication. -Kyle H On Wed, Feb 10, 2010 at 10:32 AM, newbie230 <ian_sta...@polk.com> wrote: > > Hi, > > I have lost my public key, I used this public key to generate a certificate > request which has been signed.
