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 and

The public key and the private key are usually paired. When the public key is used, the corresponding private key exists. Generally, OpenSSL and the Public Key are easily obtained from

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 key, you can do encryption and signature verification.Let's look at two ways to gener
