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.

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

encryption features: Fixed-length output: No matter how big the raw data is, the results are of the same size. Avalanche effect: small changes in input will cause huge changes in results One-way encryption algorithms: MD5 (128 bits), sha1, sha256, sha384, and sha512 Iii. encryption process and principles Iv. self-built private CA process A ① Generate a key [[Email protected] ~] # (Umask 077; OpenSSL genr

OpenSSL provides a powerful feature in this area, and is open source, now widely used in the network communication mechanism;3. By deploying a CA (Certificate authority) server within a certain scope, the certificate authentication and authorization can be realized in the LAN, and the security of data transmission can be ensured, and the working principle of the international large
