Old machine cannot boot into windows to perform a cert export. The cert file and key file have been retrieved from the file system and copied. Cert is for IE SSL access to a bank.
Certs show and claim to have private keys under properties, but export shows the key cannot be found, and when using the cert to access a Bank web site, the SSL handshake fails.
Wasn't sure so put keys here also:
Using certutil the Key Container and exact file has been identified. However, repairstore command fails.
Also, hoping to find the location of where keys may be store, FindPrivateKey was used also but without luck:
"PrivateKey failed for the following reason: Unable to obtain private key file name"
Registry of old system has been backed up also. Trying to export certificate in Windows Repair mode command prompt failed also (certutil not found).
Thank you in advance.
