Using a single AES key to encrypt PKCS #7 files

Abstract

Cryptographic systems and methods are provided. A method, according to one implementation, includes a step of generating a plurality of key pairs in response to receiving a request from a client for one or more digital certificates. The key pairs are associated respectively with the one or more digital certificates. Also, each key pair includes a public key and a private key. The method further includes a step of utilizing at least the plurality of key pairs to generate the one or more digital certificates. Also, the method includes a step of encrypting the one or more digital certificates and respective private keys using a single Advanced Encryption Standard (AES) key. The method also includes a step of sending the encrypted one or more digital certificates and private keys back to the client.
