First, enhance the security Protection tool SSH is the acronym for a Secure Sockets Layer, which is a set of programs that can be safely used to replace common programs such as Rlogin, rsh, and RCP. SSH uses public key technology to encrypt communication information between two hosts on the network and uses its key to act as an authentication tool. Because SSH e

The current password must be tested by countless people, proving that there is no trap. If you are not public, no one believes in the security of your algorithm.Many algorithms are later proven to be unsafe. Simply put, the three main foundations of modern cryptography are:1, the introduction of large prime numbers;3, the irreversible nature of the algorithm;2, based on computer operation rather than hand calculation.Based on these three points, in
