Self-built CA Based on OpenSSL and SSL certificate issuance For details about SSL/TLS, see the SSL/TLS principles.For more information about Certificate Authority (CA) and digital certificate, see OpenSSL and SSL digital certificate concepts. Openssl is a suite of open-source programs. It consists of three parts: one islibcryto, This is a general function of the encryption library, which implements a large

The Apache Wink is rapidly growing into one of the standard implementations of the JAX-RS 1.0 specification. The providers for the JSON grouping and reconciliation group included with the Apache Wink version, such as json.org and jettison, have some problems with array representation, and the return type is relatively limited. It is difficult to write Jax-rs services and their customers asynchronous JavaScript and XML (Ajax) applications. In this article, learn how to configure an existing WEB a

Common JSON libraries under Java are Gson, Json-lib and Jackson, and Jackson is relatively efficient, using Jackson for JSON and Java object transformations in the project. Here are some examples of how Jackson's JSON operations work.First, the preparatory workJackson has 1.x series and 2.x series, 2.x series has 3 jar packages to download:Jackson-core-2.2.3.jar

Names and values are separated by ":", and objects are separated; "name":"html"Object A json object contains multiple name/value pairs written in curly brackets { "name":"html","year":"5"}Array The array is included in "[]". The data objects are separated by commas (,). { "name":"html", "year":"5" }, { "name":"ht", "year":"4" }] Both web and database are an

I. Theoretical knowledge What is ca? Ca is short for Certificate Authority. It is usually translated into an authentication authority or a certification center. It is mainly used to issue digital certificates to users. This digital certificate contains part of the user's identity information and the public key held by the user. At the same time, the private key of the

Many companies now have projects based on the SOA architecture, and there are many ways in which calls are made between systems, and one common use is to return the results in JSON format using the HTTP protocol.This makes the use of JSON more common. The framework of the processing of JSON in the market is multifarious, the common Jsonobject, Gson, Jackson and so on.Now we're going to learn about Jackson a

Objective The CA is the issuing authority for the certificate, which is the core of the PKI. CA is the authority responsible for issuing certificates, certifying certificates, and administering issued certificates.It is to develop policies and specific steps to verify, identify, and sign user certificates to ensure that the identity of the certificate holder andOwnership of the public key.The

Decrypt the signature of the original data with the public key provided by Alice and verify the identity of the data sender Alice;4, using the same one-way encryption algorithm to calculate the original data signature and the decrypted signature to compare, ensure data integrity. In the process of data transmission, it is necessary for both parties to obtain the other's public key, that is, the key exchange, the public key in the network transmission process

Java JSON processing class library Jackson Jackson is a set of data processing class libraries provided for the Java platform. Jackson's main function is to provide JSON parsing and generation. In addition, Jackson also provides additional class libraries to support Avro, CBOR, CSV, Smile, XML, and YAML have powerful functions and are very good at processing JSON
