Which of the following choices is a valid Public Key Cryptography Standard (PKCS) addressing RSA?

A.
PKCS #17799

B.
PKCS-RSA

C.
PKCS#1

D.
PKCS#11

Explanation:
In cryptography, PKCS #1 is the first of a family of standards called Public-Key Cryptography Standards
(PKCS), published by RSA Laboratories. It provides the basic definitions of and recommendations for
implementing the RSA algorithm for public-key cryptography. It defines the mathematical properties of public
and private keys, primitive operations for encryption and signatures, secure cryptographic schemes, and related
ASN.1 syntax representations.
Incorrect Answers:
A: PKCS #17799 is not a valid Public Key Cryptography Standard (PKCS) addressing RSA.
B: PKCS-RSA is not a valid Public Key Cryptography Standard (PKCS) addressing RSA.
D: PKCS#11 is not a valid Public Key Cryptography Standard (PKCS) addressing RSA.
