Twobased onHTTPS replication for CA certificates ??????? I just looked at it. On the system disaster tolerance based on Kerberos and CA certificate (on) or in 2017-08-31, until now half a year passed, lazy cancer is too heavy, has not been updated, from today onwards will gradually update the beginning of the tutorial, I hope to have more friends to understand and learn Microsoft virtualization technology.
Charles Proxy, like Fiddler under Windows, can view HTTPS traffic, but when you check HTTPS requests using the CA certificate provided by Charles, the following error occurs on Firefox 35 Web page:Twitter.com uses a invalid security certificate. The certificate is not trusted because the issuer certificate has. (Error code:sec_error_expired_issuer_certificate)The reason is said to be this:
The more recent versions's Firefox only allow certs with star

Types of data encryption and the creation and application of CA certificates1. Data transmission over the Internet must be guaranteed by the following 3-point features:Privacy: Encryption of dataIntegrity: The data transfer process has not been modified.Authentication: Confirm the identity of the other, prevent the man-in-the-middle camouflage attack2. Privacy: Data encryption should use symmetric encryption, features fastThe representation algorithm
CA certificates are widely used in digital signatures, and because Windows supports RSA algorithms well, many third-party applications under the Windows platform support the application of cryptography for RSA algorithm certificates. Recently, the opportunity to take advantage of project summary, especially in Windows under the common CA Certificate digital signature application. The program is divided into

Often some enthusiastic netizens ask me about the use of the small CA system, here is a brief explanation:
1, the label with USB is the Usbkey key itself to operate, and the small CA does not have any relationship, but originally this program is used to operate usbkey, so retain these functions, usbkey use is the flying integrity epas100.

Encryption, decryption, and OpenSSL private CA
I. Common Algorithms
Common encryption algorithms and protocols include symmetric encryption, asymmetric encryption, and one-way encryption.
1. symmetric encryption: one key is used for encryption and decryption. algorithms can be made public and keys cannot be public, because encryption relies on keys. Security depends on keys rather than algorithms;
Common algorithms:
