I've managed to lose my private.key file for my SSL certificate. Is it at all possible to create a new one if I know the passkey and CSR info? If so, how do I do it?
Thanks.

The "passkey" is just for encryption of the private key, but it is chosen independently of the private key. Correspondingly, no information about the private key can be obtained from the passkey (the passkey is useful information to unlock the private key file, but you do not have that file). The certificate request contains only the public key; by construction, the private key cannot be (in practice) rebuilt from the public key (which is why the public key can be made, in fact, public). So the answer is: no, your private key is lost. If the private key could be recomputed from what you have left, then it would be cause for concern. You will have to generate a new private key, and obtain a new certificate. |
