signature of the CA certificate content (encrypted with the CA private key) hash algorithm used by the certificate holder's Public Key Certificate Signature In addition, one thing to add is:The CA itself has its own certificate, which Jianghu calls as "root certificate ". This "Root Certificate" is used to prove the identity of the CA, essentially a common digital certificate. Browsers usually have built-in root certificates from most mainstream authoritative CAS.

When using the WSHttpBinding class (using transport security) to create a self-hosted Windows Communication Foundation (WCF) service, you must also use the X.509 Certificate to configure the port. If you are not creating a self-hosted service, you can host the service on Internet Information Service (IIS. For more information, see HTTP Transmission Security. To configure the port, the tool used depends on the operating system running on the computer.

PKCS stands for public-key cryptography standards. It is a series of standards developed by the RSA lab and other security system developers to Promote the Development of public key cryptography. PKCS has published 15 standards.

sequence. the partition table contains 64 bytes, occupying the [441-509] bytes of the sector in which it is located. to determine whether the table is a partition table, check whether the two adjacent bytes ([510-511]) are "55aa". If yes, the table is a partition table. Ii. Partition Table StructureA partition table consists of four items, each of which is 16 bytes. A total of 4 × 16 = 64 bytes. Each item describes the basic information of a partitio

Decrypt received packetsAfter receiving a message encrypted by the X.509 certificate, SoapInputFilter automatically attempts to use the private key of the user key storage room for decryption. Of course, this requires to tell WSE where to find the additional configuration information for this certificate. This information is specified by the Security element of the application configuration file. In this example, the application configuration file on
