Install OpenSSL Offline on Linux: Guide

To perform an offline installation of OpenSSL on Linux, follow these steps:

1. First, download the necessary version of the source code files from the official website of OpenSSL (usually in .tar.gz or .tar.bz2 format).
2. Copy the downloaded source code files to the offline Linux system. You can use a mobile storage device (such as a USB flash drive) to transfer the files from the online system to the offline system.
3. Unzip the source code file on the offline system using one of the following commands:
4. For files in .tar.gz format: use the command “tar -zxvf “
5. For files in .tar.bz2 format: use “tar -jxvf “
6. Enter the decompressed source code directory. Use the following command: cd
7. Run the following command to configure the compile options: ./config
8. You can customize the configuration by adding various options, such as specifying the installation directory. Use the command ./config -h to view all available options.
9. Compile the source code using the following command: make.
10. Run the following command to install the compiled program and library files: sudo make install.
11. Note: This will require root or a user with appropriate permissions to execute.
12. After installation, you can use the OpenSSL command and library on your system.

The above method is a basic way to install OpenSSL offline. Please note that specific steps may vary depending on your Linux distribution and OpenSSL version. Always refer to OpenSSL’s official documentation and release notes for more detailed guidance.
