HTTPS-Certificate-Example

Create selfsign certificate using JKS keytool for HTTPS/TLS communication, among different Spring Boot applications.

To generate self sign certificate:

==================================

Step 1: goto your jre bin folder

C:\Program Files\Java\jre1.8.0_121\bin

Step 2: Then run below command:

C:\Program Files\Java\jre1.8.0_121\bin> keytool -genkey -alias https-example -storetype JKS -keyalg RSA -keysize 2048 -validity 365 -keystore https-example.jks

Or use below command

keytool -genkeypair -alias sibsankar-example -storetype JKS -keyalg RSA -keysize 2048 -validity 365 -keystore sibsankar-example.jks

Step 3:

After generation of https-example.jks certificate, copy it and put it in your spring boot application resources directory.

To view the generated jks certificate use below command:

keytool -list -v -keystore https-example.jks

To generate secret key use below command:

keytool -genseckey -alias sibs-example -storetype jceks -keyalg AES -keysize 256 -validity 365 -keystore sibs-example.jks

Openssl to generate RSA publickey/privatekey certificate

openssl genrsa -out privateKey.pem 2048 openssl rsa -in privateKey.pem -outform PEM -pubout -out publicKey.pem openssl rsa -in privateKey.pem -pubout -out publickey-1.crt
