What is the utility of .p12 file/certificate? I am not getting any correct definition when searching the internet:
In one site I got "it stores server side certificates along with intermediate certificates and private key in one file. Its mostly used in Windows Machine"
In another site i got "it binds a organizations public key with its name.
My question is whether its public key or private key which is included in the .p12 certificate.
The .p12 contains both the private and the public key, and also information about the owner (name, email address, etc. ) all being certified by a third party. With such certificate, a user can identify himself and authenticate himself to any organization trusting the third party.
You should be able to see the content of the p12 file with
openssl pkcs12 -info -in filename.p12
provided openssl is installed in your system.
