How does OpenSSL implement private CA. NOTE 1: The blue part is the main process, and the yellow arrow points to the specific operation steps. What is OpenSSL? 1. A security protocol that provides security and data integrity for network communication, including key algorithms, common key and certificate encapsulation management functions, and SSL protocols, and provides a wide range of applications for testing or other purposes;

Encryption, decryption, and OpenSSL private CA I. Common Algorithms Common encryption algorithms and protocols include symmetric encryption, asymmetric encryption, and one-way encryption. 1. symmetric encryption: one key is used for encryption and decryption. algorithms can be made public and keys cannot be public, because encryption relies on keys.

Ca:certificate Authority, a certificate authority, also known as a certification authority or certification center, is a trusted third-party entity in a PKI. Responsible for several important tasks such as certificate management tasks such as certification issuance, revocation, update, and renewal, and CRL publishing and event logging. First, the principal issues the certificate request, typically, the principal generates the key pair, and sometimes the CA
