OpenSSL is one of the utilities available with all major Linux distributions. We can use the same to encrypt and decrypt passwords in Linux to protect sensitive data.

PKCS#12 is a successor to Microsoft’s PFX format. It defines an archive file format for storing many cryptography objects as a single file. It is commonly used to bundle a private key with its X509 certificate or to bundle all the members of a chain of trusted certificates, starting from the root certificate authority. The files PFX (.pfx) and PKCS#12 (.p12), including terms, are somewhat used interchangeably and refer to same standard.
PKCS#12 are normally generated using OpenSSL, which is an open-source tool. We can use the same tool to convert JKS, which is Java keystore and PKCS#12 certs to crt and key files.

Using SSL to secure incoming and outgoing traffic from your server is always recommended. When you are developing locally or testing on a server, whether it is Windows or Macintosh or some distribution of Linux like CentOS, fedora, Ubuntu etc, its easy to put the certificate in one of the local directories and then ask server to use the same. However this becomes a little bit different if you are using Containers. Since Docker is the most popular container technology, it has become almost synonymous with containers. When using containers, you can many choices:
1) Map a local volume containing certificate files to the container and then refer to it from inside container
2) Copy certificate directly inside Container during image build process and then refer to it Read More »
OpenSSL is a robust, commercial-grade, and full-featured toolkit on the Linux that can be used for a large variety of tasks related to Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general purpose cryptography library. It is licensed under an Apache-style license, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.
It is already installed out of the box on the most linux distributions or available in the trusted package repositories. OpenSSL has been kind of standard in the open source domain to work with SSL and TLS protocols. If for some reason, it is not already installed, you can install it by using your distribution specific commands.Read More »
In one of the previous blog post, we have discovered how to build GitHub project using Jenkins. In that post, since it was a public repository, we did not tried to authenticate to GitHub. Here, we’ll cover how to use SSH keys to authenticate to GitHub repos. This applies to both public and private source code repositories.
For this post’s purposes, we’ll use a sample source code repository at https://github.com/goyalmohit/DemoRepo01. You can use any repository on which you have required access.Read More »
