Introduction to Qca
Qca aims to provide a
straightforward and cross-platform crypto API, using Qt datatypes and conventions. Qca separates the API from the implementation,
using plugins known as Providers.

Installation of Qca
Fix the location of the CA certificates:
sed -i 's@cert.pem@certs/ca-bundle.crt@' CMakeLists.txt
Install Qca by running the
following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=$QT6DIR \
-D CMAKE_BUILD_TYPE=Release \
-D QT6=ON \
-D QCA_INSTALL_IN_QT_PREFIX=ON \
-D QCA_MAN_INSTALL_DIR:PATH=/usr/share/man \
.. &&
make
To test the results, issue make
test.
Now, as the root user:
make install
Command Explanations
-D
CMAKE_BUILD_TYPE=Release: This switch is used to apply
a higher level of compiler optimizations.
-D QT6=ON: Ensure the
packages is built with Qt-6.8.1.
-D
QCA_MAN_INSTALL_DIR:PATH=/usr/share/man: Install the
qca man page in the normal location.
