Oracle 11g Web control, some operations require host identification, such as data backup, data export import and so on;This provides a certain guarantee for the security of the database. If we have the proper configuration, we can encounter some errors for the first time:ORACLE11G Host Identity Certificate problemPlease check and correct the following error and retry the operation:Error: Invalid user name and/or passwordSo at this point we need to do

Digital Certificate and Its Application in Security Testing0x00 background To perform security tests on the Web layer, it is inevitable that a man-in-the-middle proxy will be used to capture packets for analysis. Common tools include BurpSuit, Fiddker, and Charles. The usage of these tools has been described on the Internet. I will not go into details here. However, when testing websites with high security, you may encounter SSL communication problems

Handshake and communication over the SSL protocol To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption provides better identity authentication. The SSL handshake protocol is very effective for customers and servers to complete identity authentication. The main process is as follows:①

The term "digital certificate" is believed to have been heard by many people, but it is not understood that "EJBCA" may not have been heard by many peopleDigital certificate (Certificate), is the Internet communication process in the identification of the identity of the communication of a document, can be understood as "network ID", the main purpose is to verify

I. Theoretical knowledge What is ca? Ca is short for Certificate Authority. It is usually translated into an authentication authority or a certification center. It is mainly used to issue digital certificates to users. This digital certificate contains part of the user's identity information and the public key held by the user. At the same time, the private key of the CA is used to add a digital signature

One of the things faced by many network engineers is the maintenance and update of SSL certificates. For the author, SSL certificates are mainly used for VPN deployment, but there are also many network devices that need certificates to encrypt client-to-server communication. Every time I claim that I need a certificate, everyone will become speechless, and the certificate may be a bit scary for most people.

This feature is not commonly used, the general development of less related to the certificate, but it is necessary to understand briefly.First of all, the method of making the test certificate, here the old week to talk about two methods, you can generate a. pfx file for testing.To produce a certificate, everyone knows there is a makecert tool. OK, let's start wi
