What is HTTPS?.. if you don't have any idea about what is HTTPS, refer my previous blog post about HTTPS . If you have an idea about HTTPS and SSL/TLS handshake, you are good to go 😊  Creating a digital  certificate We can create a digital certificate using "Java KeyStore (JKS)". This is a repository of security certificates. We can generate a keystore file using keytool command. in order to work with keytool, you must have "JAVA" installed in your computer.  keytool is a key and certificate management utility that allows users to administrate their own public/private key pairs, and the keystore file we are going to generate bellow will also be our local tomcat server's server certificate.   Options  When creating a "keystore", we need to provide some options and values to it. -genkey/-genkeypair -alias  -keyalg  -keystore  -keysize -validity -sigalg -storepass -keypass -dname  -genkey/-genkeypair ...

What is HTTPS? HTTPS stands for "Hypertext Transfer Protocol Secure" . This is an extension of Hypertext Transfer Protocol (HTTP) for secure communication over a computer network. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or Secure Socket Layer (SSL) . Here servers and clients are still using HTTP to communicate with each other, but over a secure SSL connection that encrypts and decrypts the client-server requests and responses.  SSL ensures that all the requests and responses are directed to the legitimate destination and from a legitimate source, and also it ensures that only a legitimate server or a client can view the content of a request/response. Eavesdroppers will monitor the traffic, but they will not be able to read the content in the traffic since its encrypted. How SSL Works?  A Secure Socket Layer connection between client and server initiate with a "handshake". The goal is to satisfy the cli...
