openssl verify certificate chain

Background Due to the heart of openssl recently, I changed the ssl library 1.0.1g. I need to use this library to connect to the server. However, after I find that the Library is replaced, for some domain names, the ssl handshake will fail. In order to find out the cause of failure, we can find the handshaking status in the openssl tool.Tracking the ssl port of the Website 1. Tracking the handshake without a

Use the OpenSSL to verify the certificate chain with the following command:Debian:/home/zhaoya/openssl#openssl verify-cafile Root_cert User_certThe Root_cert can contain a lot of certif

The Http://www.cnblogs.com/wobash/archive/2009/12/29/1635246.html project encountered the problem of using OpenSSL to verify the certificate chain, looking for a long time on the internet, and found that there was very little information Through multi-party efforts, finally realized the basic function, in order to give

OpenCA:OpenCA is an open source project for building a private PKI. The author Caishuxueqian, has not studied this, hoped that has the relatively clear reader to inform how to apply to the Remote Desktop server authentication. ^-^Difficulties: The client needs to check the certificate revocation status when connecting to the server Remote Desktop. There are two ways to check certificate revocation

is, the SSL protocol can be activated to implement encrypted transmission of data between the client and the server to prevent data information leakage. This ensures the security of the information transmitted by both parties, and the user can verify whether the website he or she accesses is authentic and reliable through the server certificate.An SSL website is different from a common web site. It uses the "HTTPS" protocol instead of the common "HTT

Rsautl is a tool for RSA, a subset of the features of RSA and dgst that can be used to generate digital signatures, verify digital signatures, encrypt and decrypt files .Pkeyutl is a generic tool for asymmetric encryption, which is roughly the same as rsautl, so it only explains Rsautl here.OpenSSL rsautl [-in file] [-out file] [-inkey file] [-pubin] [-certin] [-passin arg] [-sign] [-verify] [-encrypt] [-de

SSL security certificates can be generated on their own or through a third-party CA (certification authority) Certification Center payment request. SSL security certificates include: 1, CA certificate, also called root certificate or intermediate level certificate. For one-way authenticated HTTPS, the CA certificate is
