Java Keytool Tutorial: How to generate a Self-Signed certificate using the Java Keytool
The Java keytool allows your to generate certs that you can use with applications such as Tomcat. The below tutorial will show you how to generate a self signed cert that you can use with your applications. It starts from the very beginning and shows you how to install Java, set up a key store and generate your jks cert. This guide will first show you how to download Java JDK. You will then add java to your path. Next you will use the Java keytool to create a Java keystore You will then generate a Self-Signed cert using the Java Key tool. This cert will be in JKS format. Finally you will view the certificates in the keystore to see the cert which you generated using java keytool commands. A full text tutorial can be found here: https://darrenoneill.eu/?p=553

Create Your Own Self Signed X509 Certificate
In this WiBisode Kevin will show how you can create signing certs for creating digital signatures! This is most often used to "lock" documents in a particular state, and then verified by the consuming application. The point of digital signatures is to create an application "trust" between two entities. When the consumer receives the document, it can validate the signature against the public key and feel confident that the document was "signed" by a trusted private key. #WiBisode #SelfSignedCertificate #SelfSigned #Certificate #OpenSSL #WiBitNet

How does HTTPS work? What's a CA? What's a self-signed Certificate?
Is HTTPS really that difficult? Do I need to know crypto theory and a lot of math to understand it? You don't! This video explains how HTTPS works in very simple terms. It will touch upon encryption and digital signatures, as well as explaining what a trusted Certificate Authority is and what a self-signed certificate is. We will build upon this knowledge in upcoming videos, when we plan to issue a self-signed certificate to secure a microservice app in a testing environment. You no longer have an excuse to say HTTPS is too complex. Because this video simplifies all the concepts in less than 12 minutes.

Why digital certificate?
Digital Signature: https://www.youtube.com/watch?v=TmA2QWSLSPg&t=2s Digital signature is used for authentication, non-repudiation and data integrity, but there is one weakness of digital signature alone: man-in-the-middle attack. Digital certificates are electronic credentials issued by a trusted third party. A digital certificate not only verifies the identity of the owner, but also verifies that the owner owns the public key. In this video, I will demonstrate why digital signature has weakness and how digital certificate comes in place to make sure digitally signed document must come originally from the claimed sender.

Create a private-public key pair using Backup4all
Every digital certificate has a pair of associated cryptographic keys. This pair of keys consists of a private key and a public key. A public key is part of the owner's digital certificate and is available for anyone to use. A private key, however, is protected by and available only to the owner of the key. This limited access ensures that communications that use the key are kept secure.

Public Key Infrastructure Fundamentals - Bart Preneel
The function of a public key infrastructure (PKI) is to ensure secure delivery and management of public keys. Alternative trust models lead to different key architectures. Public keys are published by means of digitally signed certificates. A private key may be compromised, in which case the certificate containing the corresponding public key must be revoked. Many revocation methods are in current use. Publication of Certificate Revocation Lists (CRLs) and checking with an Online Certificate Status Protocol (OCSP) responder are best established. Learning objectives + learn the components of a public key infrastructure. + understand key delivery and management mechanisms. A lecture by Bart Preneel at SecAppDev 2013 in Leuven, Belgium. Professor Bart Preneel of KU Leuven heads the COSIC (COmputer Security and Industrial Cryptography) research group. His main research area is information security with a focus on cryptographic algorithms and protocols as well as their applications to both computer and network security, and mobile communications. He teaches cryptology, network security and coding theory at the K.U.Leuven and was visiting professor at the Ruhr Universitaet Bochum (Germany), the T.U.Graz (Austria), the University of Bergen (Norway), and the Universiteit Gent (Belgium). In '93-'94 he was a research fellow at the University of California at Berkeley. He has taught intensive courses around the world. He undertakes industrial consulting (Mastercard International, S.W.I.F.T., Proton World International,...), and participates in the work of ISO/IEC JTC1/SC27/WG2. Professor Preneel is Vice President of the International Association for Cryptologic Research (IACR) and co-founder and chairman of LSEC vzw (Leuven Security Excellence Consortium).

Creating a Self-Signed Certificate
There are generally two options for obtaining a digital certificate (and a private key). 1. You can generate your own certificate using the Cerberus Create Cert button. 2. You can obtain a certificate from a recognized Certificate Authority Which is more appropriate really depends upon your goals. If you just want to make sure that client and server connections are securely encrypted then a self-signed certificate is all you need. It has the benefit of being easily created through Cerberus and completely free.
