PKCS #7
Cryptographic Message Syntax Standard
A PKCS #7 file can be used to store certificates, which is a signeddata structure without data (just). The file name extension is usually. p7b,. p7c
PKCS stands for public-key cryptography standards. It is a series of standards developed by the RSA lab and other security system developers to Promote the Development of public key cryptography. PKCS has published 15 standards. Commonly used:PKCS #7

The concepts related to certificates are really tricky because they haven't been exposed to certificate encryption before, because there's a whole new term coming up that looks like something else in another field, not something that we're familiar
