BouncyCastle is an open source Java library which implements a dazzling array of cryptographic algorithms, and where possible, they have been made available via the standard JCA provider interface.In terms of JOSE algorithm support, BouncyCastle can handle all those that are not covered out-of-the-box in Java 7 and 8.How do you set up the BouncyCastle JCA provider in your application?First, add ..

The Java Cryptography Extension (JCE) provider included with J2SE 1.4.x does not support RSA encryption. Because the XML Encryption defined by WS-Security is typically based on RSA encryption, in order to use WS-Security to encrypt SOAP messages you must download and install a JCE provider that supports RSA encryption. If you are running the Application Server on version 1.5 of the Java SDK, the..

By default Java supports only 128-bit encryption and you need to download and install Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files to support 256-bit AES encryption. Here are the steps to fix java.security.InvalidKeyException: Illegal key size exception: 1. Visit Oracle’s website and put ‘Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy F..

Subject to class loader constraints the Bouncy Castle Provider can be installed either dynamically or statically.Note: to make full use of the provider you *must* install the unlimited policy files in the JVM you are using - these can be downloaded from http://java.sun.com. Be careful if you are using Windows as the JDK install will normally install a JRE and a JDK in two separate places - gener..

Test automation 관련해서 회의를 하다가 JAVA code 기반으로 unit test를 자동 작성해 주는 tool 얘기가 나왔다.유용하다는 말에 찾아보니 해당 tool은 상용인 AgitarOne 이었네.홈페이지는 http://www.agitar.com/ 여길 참고하고, 소개 영상은 https://youtu.be/ONRFG30g-cw 여기서 확인해 보자. 이외에도 찾아보니 유사한 것들이 많은데 EvoSuite 괜찮을 듯.홈페이지는 https://youtu.be/ONRFG30g-cw 여길 참고하고 소개 영상은 https://www.youtube.com/watch?v=R0K6VGhqbqg 여기서 확인해 보자. http://mit.bme.hu/~micskeiz/pages/code_based_test_..
