How to use pfx certificate in postman?

Question

There is a way to import a .pfx certificate in postman? I need to send a user certificate for testing my API.

Answer 1

At the time of writing this answer Postman didn't support .PFX files. Ref: Feature Request: Support for PFX

However you can extract cert and private key from the .PFX file using openSSL and configure those in Postman.

Extract key:

openssl pkcs12 -in pfxfile.pfx -nocerts -out key.pem -nodes

Extract cert:

openssl pkcs12 -in pfxfile.pfx -nokeys -out cert.pem

Answer 2

Postman Canary Update has support for PFX Files now. You may use that build instead.
