File extension: P7C


Notes about the P7C file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The P7C file type is primarily associated with 'PKCS #7 Certificate'. In cryptography, a public key certificate (or identity certificate) is a certificate which uses a digital signature to bind together a public key with an identity. The certificate can be used to verify that a public key belongs to an individual. See Section 3.2 in RFC 2311. (Degenerate signedData certs-only message.)
