Java security tutorial-create an SSL connection and CertificateThis article is translated from javacodegeeks by ImportNew-hejiani. Welcome to the Java group. For more information, see the requirements at the end of the article.
In our series of articles on Java EE security, we have also described in detail how to create SSL connections and certificates in Java EE applications. As mentioned in the previous a
OpenSSL Toolkit is one of the implementation methods of SSL v2/V3 and TLS v1 protocols on Linux, and provides common encryption and decryption functions.
OpenSSLIt consists of three parts:
1:Libcrypto: an encrypted library mainly used to implement encryption and decryption.
2:Libssl: implements the SSL server-side function session Library
3:OpenSSL command line tool:/usr/bin/OpenSSL
This document only describes how to use the OpenSSL command to

How to create an imap ssl self-signed certificate
Today, I think the imap ssl self-signed certificate is incorrect. I can check it online, and no one can say it completely.
Clearly, there is no way. Please take a look at the official documentation and take a look at man page. Now I am studying
I understand what is going on. Just give it a brief look. (As a memo)

Before you enable HTTPS, you need a valid certificate, and if you already have a valid certificate, you can skip this step directly and go to step 2.You can create a self-signed certificate, or get a certificate from a trusted Certificat

There are two methods of testing for iOS development and software testing.
The first: iOS developers write a good project to the SVN server, the testers download the project code, configure the compilation environment, open with Xcode, and then run check bugs on the phone side.
The Second: iOS developers package the project into an IPA file, and with the help of the third medial dandelion platform, the tester can simply scan the QR code to download the software and then check the bug.

Although iOS7 can be tested on a real machine without a certificate, many operations still have to have a certificate in order to operate normally;Preparation: You have to have a developer account first;Generating a test certificate requires three steps:1. Generate a certificate file2.

However, how does the client verify whether the server certificate is true? a ca: a third-party Certificate Authority is required to issue a certificate to our server. Therefore, the client can go to the CA to verify the server certificate.
