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.

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

Create self signed certificates with Subject Alternative Names
This video explains how to create a self signed certificate with Subject Alternative Names (SAN). A certificate with Subject Alternative Names is a single certificate supporting multiple Common Names (CN), for example: - mobilefish.com - sand.mobilefish.com - baidu.com - china.com This means this single certificate can be used in multiple URLs: - https://mobilefish.com - https://sand.mobilefish.com - https://baidu.com - https://china.com Chrome browsers will issue a warning if your SSL certificate does not specify Subject Alternative Names. This video assumes that you have installed OpenSSL. More information how to install and use OpenSSL:https://www.openssl.org To check if your system has OpenSSL installed, type: openssl version -a The procedure to create self signed certificates with Subject Alternative names is also documented at: https://www.mobilefish.com/developer/apache/apache_quickguide_install_macos_sierra.html Warning: Never use self signed certificates in production environments. It is okay to use it in development or testing environments. 1. Create a 2048 bit Certificate Authority (CA) private key: sudo openssl genrsa -out privkey.pem 2048 The CA private key is created: privkey.pem 2. Create a self signed CA certificate: sudo openssl req -new -x509 -days 3650 -nodes -key privkey.pem -sha256 -out ca.pem 3. Create a 2048 bit Certificate Authority (CA) certificate: Country Name (2 letter code) [AU]:NL State or Province Name (full name) [Some-State]:Noord-Holland Locality Name (eg, city) []:Zaandam Organization Name (eg, company) [Internet Widgits Pty Ltd]:Mobilefish.com CA The CA certificate is created: ca.pem 4. Create a server configuration file (server.csr.cnf). Example: https://www.mobilefish.com/download/openssl/sand.mobilefish.csr.cnf.txt Download and modify the server configuration file according to your situation. [dn] C=NL ST=Zaandam L=Noord-Holland O=End Point OU=Research and development [email protected] CN = sand.mobilefish.com 5. Create a server Certificate Signing Request (CSR) and server private key. sudo openssl req -new -nodes -out server.csr -keyout server.key -config server.csr.cnf The server CSR is created: server.csr The server private key is created: server.key 6. Create a server extension file (server_v3.ext). Example: https://www.mobilefish.com/download/openssl/sand.mobilefish_v3.ext.txt Modify the server extension file according to your situation. Add Subject Alternative Names: [alt_names] DNS.1 = sand.mobilefish.com DNS.2 = proxy.mobilefish.com In the sever configuration file (server.csr.cnf) I have used “CN = sand.mobilefish.com". This common name must be mentioned as one of the Subject Alternative Names. 7. Create the server certificate: sudo openssl x509 -req -in server.csr -CA ca.pem -CAkey privkey.pem -CAcreateserial -out server.crt -days 3650 -extfile server_v3.ext  The server certificate is created: server.crt The serial number file is created: ca.srl Each issued certificate must contain a unique serial number assigned by the CA. It must be unique for each certificate given by a given CA. OpenSSL keeps the used serial numbers on a file. The server certificate (server.crt) and server private key (server.key) are the two files you need to install on your server (Apache web server, proxy server). Always keep the private keys secure: - CA private key (privkey.pem) - Server private key (server.key) Recap We have created our own Certificate Authority (root certificate). But this CA is not trusted by our system. Next our CA has created a certificate with SAN. Trusted CA’s such as Comodo and GoDaddy are trusted because their root certificates are already imported in our system. In YouTube video “Geth supporting SSL using reverse proxy server” I will be using this self signed certificate to setup a reverse proxy server accessible by: https://proxy.mobilefish.com.

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.

What are certificates?
Certificates are used to prove identity and used for creating secure communication. Check out http://itfreetraining.com for more of our always free training videos. This video looks at how a certificate works, what is a certificate and how they are used for identification and secure communication. Download the PDF handout http://itfreetraining.com/Handouts/Certificates/WhatAreCertificates.pdf What is a certificate? A certificate is an electronic document that contains data fields. When compared to a traditional paper certificate there are some similarities between an electronic certificate and a physical certificate. Digital certificates like a physical certificate are issued by an authority. For example, a university may issue a certificate to a student to show that they have completed the necessary work in order to graduate. The next question is, would you trust a physically certificate? Digital certificates work the same way. They are issued from an authority and the question becomes would you trust the authority that issued the certificate? Electronic certificates also contain other fields like who or what the certificate was issued to, how long it is valid, the public key and the digital signature. If a digital certificate is presented to a user or computer, the user or computer is able to check the certificate to ensure the person using it should be using it. Also the certificate contains a digital signature which allows the certificate to be checked to make sure it has not been modified. Digital Signature A digital signature provides a method for a certificate to be checked to ensure it has not been modified. In order to do this, a hash value is created for the certificate. To generate a hash value the certificate is put through a function to create a single value. Hash functions are designed so different certificates will not produce the same value, however the hash value cannot be used to generate the original certificate. The same principal applies to a person's fingerprints. They can be used to identify a person, however using a finger print you could not work out the features of a person like what color hair they have. When a certificate is created, the hash value for that certificate is also created. Using a function involving the private key, a digital signature is created and added to the certificate. Digital Signature Example When a certificate is used, in order to check the certificate has not been changed, the following is done: The computer generates the hash value for the certificate. Next, the digital signature is put through a function using the public key which should result in the same hash value. If both values match, the certificate has not been modified. This prevents a 3rd party taking a certificate, changing the values in the certificate and using the certificate. Trust Model Certificates work off a trust model. An example of a trust model in computers is that a computer may have a sticker on it indicating which operating systems it will run. The consumer, seeing this sticker, must trust that the manufacture would not put this sticker on the laptop unless it will run that operating system. The customer must also trust the creator of that operating system would not allow a computer manufacturer to put a sticker on a computer that would not run that operating system. Certificate Trust Model Certificates are generally deployed in a hierarchy. At the top is the root certificate authority. This can be an internal Certificate Authority or an external authority like VeriSign. When an authority like VeriSign issues a certificate, they will perform a number of checks on the individual purchasing the certificate to ensure that they are a valid business. When a certificate is used it can be checked to see which authority issued that certificate. In order for the certificate to be used, the computer must trust the authority that it was issued from. Authorities like VeriSign are trusted by default on most operating systems. Certificate Error If a certificate is presented to the computer and it is not trusted, the computer will generate an error asking if the users want to trust the certificate. It is up to the user to decide if they believe the certificate is valid. Certificate Hierarchy Certificates use a hierarchy. At the top is the root CA, below these are subordinate CA's. Any level can issue certificates to subordinate CA's or direct to users, computers or devices. If the user, computer or device trusts the root CA, then any certificate that is issued by any CA in the hierarchy will automatically be trusted and thus used by the client.

What is a certificate authority?
Establishing a secure communication channel is important—​but how do you know you are communicating with the right entity? The structure of the internet makes it easy to launch so-called man in the middle attacks. This allows even secure communication channels to be established with the wrong site or computer. Alternatively, phishing attacks may try to confuse users by mimicking the look and feel of websites they are used to—​like their bank’s site. On the web this problem is solved using so-called certificate authorities. A small number of trusted entities provide a basis on which the legitimacy of other sites can be established.

Private Key Encryption (Symmetric Key Encryption)
In private key encryption, data is encrypted using a single same key that only the sender and the receiver know. That is why private key encryption is also called symmetric key encryption because the same key is used during both encryption and decryption of the transmitted data. In this video, I will also use an example to demonstrate the process of using private key encryption. Two different methods -stream encryption and block encryption- of private key algorithm are also depicted with animation.
