Converting cer (with csr and key) to pfx

Question

¿I can make a PFX certificate from cer , csr and key files?

Actually I have this files

• ceti.cer
• ceti.csr
• ceti.key

Answer 1

The -in should be .cer file and the -certfile should be .cabundle.pem, you don't need the csr request once it have been signed by root/intermediate CA. So the correct syntax is:

openssl pkcs12 -export -out ceti.pfx -inkey private.key -in signed.cer -certfile cabundle.pem

to bundle the root/intermediate pem files run something like:

cat root.crt intermediateca.crt subordinateca.crt > cabundle.pem

Answer 2

This command helped me:

openssl pkcs12 -export -out user.pfx -inkey user.key -in user.cer -certfile rootca.crt

the responses above returned an error "Unable to load certificates".

Answer 3

Edit: Command has been fixed. Be sure your ceti.cer is PEM encoded

You could use the command :

openssl pkcs12 -export -out ceti.pfx -inkey ceti.key -in ceti.cer
