When developing a mobile website, we must use the "ssl client certificate" to deploy encrypted websites that are only accessible to specific mobile phones ", Does all mobile phone systems support ssl client certificates well? Let's see how to use various mobile phone systems to access websites with ssl client certificates. IPhone, Android 4.0 or above, BlackberryThe built-in browsers of

How to use Java code to automatically Import SSL certificates to Java's key storage file (keystore), sslkeystore In the process of developing or using SSL, many software products need to provide java keystore, especially some Java-based middleware Products.The general practice is to use the built-in JDK tool command (keytool), for example, the following example Keytool-import-v-alias EnTrust2048-file D: \ certs \ EnTrust2048.cer-keystore D: \ certs \

Solution for failure of all certificates in the iOS-key string (invalid issuer of the certificate), ios-Key Today, I used Xcode to package the IPA file to my colleagues. When the result showed that the import was prompted, I was prompted for the certificate missing. After finding the file for a long time, I did not find any problem. Then I opened the key string and found that all the certificates were inva

verify the certificate. If it is correct, it will download the default page index.html. Note: The trust manager determines whether the remote certificate is trustworthy. It uses the following rules: 1. If the system attribute of javax.net. SLL. truststore specifies a trusted library, the trust manager checks the certificate using the provided file. If the system property exists but the specified file does not exist, no trust library is used and a certificateexception is thrown. 2. If the system

Tags: multi-domain certificate OpenSSL sign multi-domain certificate nginx two-way authentication SSL multi-domain Certificate OpenSSL self-built ca signs a Single Domain Name Certificate by default, because a single server has multiple HTTPS domain names, it is much easier to sign a multi-domain certificate, today I have been looking for a long time, except for some websites that sell certificates that have SCR tools that can add "User backup names",

"save to disk", then the user e-mail address can be a random name, the common name is the best to make a meaningful distinction between the name, CA e-mail address to fill in their own mailbox. The user email address can be the same as the CA e-mail address, so you can accept the message anyway.Save the file to the desktop (for easy querying), the first. Cersigningrequest. The other two are generated by the following steps: A. cer is the certificate that waits until

OpenSSL configuration file:/etc/pki/tls/openssl.cnfThree strategies: matching, support, and optional. Match: The information required to fill in the request must be consistent with the CA setup information; Support: means the application information must be filled in; optional: means dispensable.Experimental environment: Requires two hosts, I here with Host a (centos6:ip for 172.17.250.83) to create a CA and to other hosts to provide CA services; host B (centos7:ip is 172.17.253.204) is a httpd

OrderThe first two of the basic concepts and composition are roughly said, today's article, mainly about how to use Java code to generate a CA certificate, as well as when generating certificates, you need to set some properties.BodyNonsense not much to say, directly on the content.Here is the Java API, and a third-party component,--BC, (bouncy Castle). A little introduction to the Bc,bouncy Castle is a lightweight, open-source cryptographic package f

1. Key, certificate request, Certificate Summary descriptionDuring the certificate request issuance process, the client involves the concepts of keys, certificate requests, certificates. We describe the relationship of the three in the process of applying for a certificate. Clients (as opposed to CAS) have roughly three steps to apply for a certificate:The first step: generate the client's key, the client's public private key pair, and ensure that the

encrypts the key in the data and transmits it to the server, the server decrypts it with the private key, obtains the private key from the data, and then encrypts the returned data with the private key and transmits it to the requesting party. The requester decrypts the secret key from the previous protocol.Certificates and CAsThere is one more question: How does the server send the public key to the requestor's hand? It's about certificates and CAs.

Reproduced from the sub-non-fish blog slightly modified the first step: rely onTo configure the Apache server to support the HTTPS protocol and SSL certificate, the most basic requirement is that Apache contains the OpenSSL module. Fortunately, the Apache/bin directory has libeay32.dll ,, openssl.exe ssleay32.dll and comes with the SSL module, if not the module, you need to download a separate OpenSSL.Step two: Start the moduleBoot module is relatively simple, open Apache configuration file conf

Those related to certificates (SSL,X.509,PEM,DER,CRT,CER,KEY,CSR,P12, etc.) [ZZ]Reprinted From:http://www.cnblogs.com/guogangj/p/4118605.htmlThese concepts related to certificates are really tricky because they haven't been exposed to certificate encryption before, because there's a whole new term coming up that looks like something else in another field, not something that we're familiar with in the progra
