Because I often deal with Linux servers at work, I used an SSH key pair-based automatic login to avoid Frequent password input during switching between servers. The following describes the principle of RSA/DSA keys.
Let's start with a hypothetical scenario, assuming that we want to use RSA Authentication to allow a local computer (called localbox) to open a remote shell on remotebox, remotebox is a machine

Public-key authentication is the use of a pair of cryptographic strings, a public key, which can be seen by anyone, used for encryption, and another known as a key (private key) that only the owner can see for decryption.When using Jenkins to automatically build and remotely log on to the server for publishing applicat

Primary Key constraints automatic index creation constraints are used to ensure the integrity of database data. In oracle databases, you can use constraints, triggers, and application code (processes, functions) to achieve data integrity, among the three methods, the constraints are easy to maintain and have the best performance, so the constraints are preferred for data integrity. i. constraint classificat
