What is Keychain Access?

Keychain Access is listed in our database as a program that opens or converts the file formats shown on this page. It runs on macOS. The formats it works with include .PEM, .P7B and .P7C.

You can get the official version from the developer's website (support.apple.com); we do not host the installer and only point you to the original source. A detailed, hand-checked description of Keychain Access is on the way; for now the information here comes straight from our database.
