MongoDB uses keyfile access control to deploy replica sets (instance tutorial), mongodbkeyfileIntroduction Configure the replica set's mandatory access control: The internal authentication mechanism is used to ensure the security of replica set members. role-based access control is used to ensure the security of the connected client and replica set. In this tutorial, each member of the replica set uses the same internal authentication mechanism and settings. Forced internal authentication enforc

Encrypt messages sent externallyI have modified the previous GetXmlDocument method so that it can use the X.509-based asymmetric encryption technology implemented by WSE. The FindCertificateBySubjectString method can be used to receive public backups of client certificates, a client certificate from the personal storage room of the Local Machine Account. This certificate is then used to create a new X.509 S

Different certificates are stored in different formats (such as whether the public key or private key is encrypted for storage, a single certificate, or multiple certificates), and are encoded differently (der/base64) different standards (such as PEM/PKCS), so although the X.509 standard specifies the certificate content specification, the certificate files are still varied. Fortunately, OpenSSL has good support for these different standards and can b

In addition, you can use the X.509 Certificate to sign and verify the XML without using the platform call. It also supports PKCS7 signature and encryption and CMS (PKCS7 standard superset available on Microsoft Windows 2000 and later operatin

Transmission security guaranteed by basic identity authentication Demonstrate a Windows Communication Foundation (WCF) service and client. The server requires a valid X.509 Certificate for Secure Sockets Layer (SSL), and the client must trust this server certificate. In addition, the Web service already has an SSL implementation that can be used. For more information about enabling basic authentication in Internet Information Service (IIS), see http:/
