cURL with SSL certificates fails: error 58 unable to set private key file

Question

I\'m trying to connect to a remote host using cURL. The connection requires the use of a certificate and a private key which is password protected. So far I\'m unsuccessful

Answer 1

I've fixed this problem. I think, due to the number of questions regarding this issue and number of different solutions, others will benefit from the solution. Here goes:

I used the openssl CLI program to convert the .p12 key-file to a .pem key-file. The trick is the way the conversion takes place.

First I converted it with this command and I had the issue as described in the question:

openssl pkcs12 -in key.p12 -out key.pem -nodes -clcerts

While the command below did the actual trick:

openssl pkcs12 -in key.p12 -out key.pem -clcerts
