Convert Cert + Key to PEM and PFX

See more Certificates Examples

This example is based on the following question from a Chilkat customer:

We receive 2 files :

    MyCertificate.p7b
    MyCertificate-privatekey.pkey

We have to transform these certificate like this:

First convert it to PEM like this:

openssl pkcs7 -in MyCertificate.p7b -inform DER -out MyCertificate.pem -print_certs

Now we get MyCertificate.pem

Last step, we need to convert it to pfx file:

openssl pkcs12 -export -inkey moncertificat-privatekey.pkey  -in  moncertificat.pem -out moncertificat.pfx

Is there a way to make all these steps with Chilkat ?

I will be nice to include this directly in our software instead of askig the user to do it manualy.

? "Success."
