How do I upgrade openssl version in my digital ocean droplet?

Heya,

Confirm the version of OpenSSL installed:

openssl version

Update your system to ensure all dependencies are up-to-date:

sudo apt update && sudo apt upgrade -y

That should do it for you. If it doesn’t update it means that’s the newest one for your Distro:

https://launchpad.net/ubuntu/jammy/+source/openssl

The above states that the latest official openssl version that is supported is 3.0.2.

Heya, @mdhabiburrahmantalukdershamim

1. Visit the OpenSSL downloads page to get the latest stable version (3.4.0 at this time).
2. Download the tarball:

wget https://www.openssl.org/source/openssl-3.4.0.tar.gz

3. Extract the tarball:

tar -xvzf openssl-3.4.0.tar.gz 
cd openssl-3.4.0

1. Configure and build OpenSSL:

make 
sudo make install

2. Verify the installation path: The new OpenSSL binary should be installed in /usr/local/bin. To ensure the new version is used, update the symbolic link:

sudo ln -sf /usr/local/bin/openssl /usr/bin/openssl

3. Update the library paths: Add /usr/local/lib to your library path:

echo "/usr/local/lib" | sudo tee -a /etc/ld.so.conf.d/openssl-3.4.0.conf 
sudo ldconfig

Check the OpenSSL version again:

openssl version

It should now show OpenSSL 3.4.0
