Install OpenSSL Offline on Linux

To install and configure OpenSSL offline on Linux, you can follow these steps:

1. Download the OpenSSL installation package: Obtain the latest version of the OpenSSL installation package from the official OpenSSL website (https://www.openssl.org/source/), and then transfer the package to your Linux system.
2. Extract the installation package: Open the terminal in a Linux system and use the following command to extract the OpenSSL installation package.

tar -zxvf openssl-x.x.x.tar.gz

(Note: Replace “openssl-x.x.x.tar.gz” with the filename of the OpenSSL installation package you downloaded.)

1. Navigate to the decompressed directory: Use the cd command to enter the decompressed OpenSSL directory, for example:

cd openssl-x.x.x

1. Configure and compile OpenSSL by running the following command:

./config --prefix=/usr/local/openssl
make
sudo make install

This will install OpenSSL on your system and place it in the /usr/local/openssl directory.

1. Set up the OpenSSL environment variables by editing your bash configuration file (such as ~/.bashrc or ~/.bash_profile) and adding the following line to configure the OpenSSL environment variables.

export PATH=$PATH:/usr/local/openssl/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openssl/lib

Save the changes and run the following command to apply the changes:

source ~/.bashrc

You have now successfully installed and configured OpenSSL offline on your Linux system. You can use the openssl command to verify if OpenSSL has been installed correctly.
