How certificates are registeredIn Windows2012, we can register a certificate for a user or computer in many ways, and the certificate is registered in a way that is relevant to the environment, for example, we want to use autoenrollment to bulk deploy certificates to a large number of users or computers, but in some cases We also need to deploy the certificate to

I. Using RSA certificates to encrypt and decrypt sensitive dataThe certificate standard supports three kinds of asymmetric encryption algorithms: RSA, DSA, Diffie-hellman algorithms. The most common is the RSA algorithm. So this article is encrypted and decrypted using the generated Mytestcert certificate generated by the MakeCert tool in the previous section, which has a 1024-bit key pair for the RSA algor

Digital Certificate is a common content in computer security. On the network, the most common situation is probably the use of SSL secure connections. I will not introduce the digital certificate, RSA algorithm, DSA algorithm, message digest, mutual SSL, and other content. Anyone who needs it should be familiar with it. If you are not familiar with it, but want to learn more, here is a very simple tutorial:
TripleDES).
PKCS#12 is the public key encryption standard, which stipulates that all private keys, public keys, and certificates can be included. It is stored in binary format, also known as a PFX file, that can be imported directly into the key area in Windows, noting that pkcs#12 's KeyStore protection password is also used to protect key.
BKS from Bouncycastle Provider, which uses tripledes to protect keys in the KeyStore, prevents the
The SSL certificate formats used by different platforms and languages are often different. Here we record some common conversion methods.
All are converted using OpenSSL or keytool. You do not need to implement the conversion using your own code. You can replace the corresponding file name in use.

The Keytool is an effective security key and certificate management tool. The Keytool.exe (located in the Jdk\bin directory) in Java can be used to create a digital certificate, and all digital certificates are stored in a certificate library in a single article (distinguished by Alias), and a certificate in the
With the development of the Internet, it has been deeply in all aspects of people's lives, it can be said that we are inseparable from the Internet. In the face of human dependence, Internet security is increasingly important, personal privacy is increasingly needed to protect. How can we improve the security of our Internet access? How to protect the privacy of our internet? How to prevent being hijacked by hackers? And so on, many security factors need to be taken into account.HTTPS has gradua

This is a very interesting experiment.
As you know, certificates issued by some SSL certification authorities are installed on the server side, allowing visitors to access the site through SSL links, and can confirm the site's true address to the visitor. However, if you want to restrict the visitors to your site, you need to verify the certificate that the client owns so that you can establish a secure link. and the organization in the issuance of SS
