Download the source code for cryptlib (cl341.zip) and enter
the directory using the terminal. Then run the following:

unzip -a cl341.zip -d cryptlib
cd cryptlib

make shared

sudo cp libcl.so.3.4.1 /usr/lib/
sudo ln -fs /usr/lib/libcl.so.3.4.1 /usr/lib/libcl.so

Note: Make sure the terminal commands are used to extract the
zip file because otherwise the make command may not work.
