A certificate is linked to the specific private key it was created for. The modulus of that key was stored in the CSR that was used to generate the certificate. You need to find the correct key, since you won't be able to generate a matching one. You can check the modulus of the key, csr and certificate with openssl: openssl x509 -noout -modulus -in certificate.crt openssl rsa -noout -modulus -in private.key openssl req -noout -modulus -in csr.csr You probably should check the certificate as well, especially the CN of the Subject, e.g. with openssl x509 -noout -text -in certificate.crt rainer --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
