The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured.
The RSA algorithm consists of the generation of public

First, we need to distinguish the two basic concepts of encryption and authentication.Encryption encrypts data so that illegal users cannot obtain the correct data even if they have obtained the encrypted data. Therefore, data encryption can protect data and prevent attacks. The focus is on data security. Identity Authentication is used to determine the authenticity of an identity. After the identity is confirmed, the system can grant different permissions according to different identities. The
In general, the current SaaS service provides the current SDK or API docking service that involves an authentication and data encryption issue. It is generally common practice to configure the use of asymmetric encryption to solve this problem, you hold the public key of the SaaS company, the SaaS company holds your public ke

Abstract:
This article briefly introduces the ideas and features of the public key cryptography system, and introduces the theoretical basis, working principle and implem
SSH does not have password logon to use the public key and private key. Linux can be used to generate a public/private key pair with Ssh-keygen.There is a machine a,b (192.168.0.32). Now want a password to login to B via SSH.
1. Generate a
Gitlab Add the part of the deployment public key is a bit strange, although the gitlab of the deployment public key is in the database, but actually directly add database records can not be used, there will be no access, and usually do third-party access is generally directly added to the database, so this is a headach
For the open-source hosting site GitHub Everyone should be familiar with it, has been set up in GitHub above the SSH public key, there has been no problem, today encountered a problem: Git also push code to two remote repositories. So I built two test remote warehouses on GitHub and OSC, but I didn't use the OSC very often, so I had the SSH public
