SFTP Receiver-Private Key Authentication

Hello Experts,

I'm configuring SFTP receiver adapter with Private Key Authentication.

All i got is a .ppk file generated using PUTTY key generator.

And we need certificate in PCKS12(.p12) format to import it in PI.

Going through the forums got to know that OPENSSL is used to convert ppk to p12 format.

Can somebody guide me how to achieve this as i dont have idea about OPENSSL.

P:S I'm using PI 7.40.

Thanks,

Glory.
