RFC 1321: MD5 Message Digest Algorithm (rfc-editor.org)https://www. rfc-editor.org/rfc/rfc1321 official reference document, you can directly copy the code in References. After the MD type is defined as 5, it can be successfully executed by directly using the code inside. The MDString function can actually be used after changing it. The following is Understand the execution process […]

Springboot Cangqiong takeaway practice: 2. nginx reverse proxy and load balancing configuration + MD5 encryption + Apifox import interface document + Swagger (knife4j version, including common interface annotations)
nginx reverse proxy and load balancing Observing the project code, we can find Front-end request address: http://localhost/api/employee/login Backend interface address: http://localhost:8080/admin/employee/login Obviously, the two addresses are inconsistent, so how do you request the backend service? This is a reverse proxy through nginx. The front-end request is forwarded to the back-end through nginx, thereby realizing the […]

MD5 is a nice guy / MD5 is a nice guy
md5 is a digest generation algorithm that can verify whether the message has been tampered by generating a unique digest for the message. As we all know, md5 is widely used in the security control of http interface communication. By adding the merchant’s communication secret key to the original signature string, the MD5 operation is […]
