Generating PFX file from crt and pem file

Question

I have following files:

• root.crt
• intermediate1.crt
• intermediate2.crt
• privatekey.pem

I tried to generate a pfx file with openssl

openssl pkcs12 -export -out certificate.pfx -inkey privatekey.pem -in root.crt -certfile intermediate1.crt -certfile intermediate2.crt

Which gives me following error:

No cert in -in file 'root.crt' matches private key
68310000:error:05800074:x509 certificate routines:X509_check_private_key:key values mismatch:crypto\x509\x509_cmp.c:405:

Is there something wrong with my private key?

Answer 1

The root.crt was not matching with the private key. After using the correct crt file it worked.

Answer 2

Private key specified with '-inkey file' should match the cert specified with '-in file'.
