CrypTool 1 is e-learning software for cryptography and cryptoanalysis.

CrypTool 1 (CT1) is a free program for cryptography and cryptanalysis. CT1 is available in 6 languages, and it is the most widespread e-learning software of its kind.

CT1 supports both contemporary teaching methods at schools and universities as well as awareness training for employees and civil servants. The program can be downloaded here.

Originally designed as an internal business application for information security training, CrypTool 1 has since developed into an important open-source project in the field of cryptology and IT security awareness.

The current version of CrypTool 1 offers among other things:

Numerous classic and modern cryptographic algorithms (encryption and decryption, key generation, secure passwords, authentication, secure protocols, etc.)
Visualization of several algorithms (Caesar, Enigma, RSA, Diffie-Hellman, digital signatures, AES, etc.)
Cryptanalysis of several algorithms (Vigenère, RSA, AES, etc.)
Cryptanalytical measurement methods (entropy, n-grams, autocorrelation, etc.)
Related auxiliary methods (primality tests, factorization, base64 encoding, etc.)
Number theory tutorial

Enable snaps on Red Hat Enterprise Linux and install CrypTool 1

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.

Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.

The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.

The EPEL repository can be added to RHEL 9 with the following command:

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade

The EPEL repository can be added to RHEL 8 with the following command:

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade

The EPEL repository can be added to RHEL 7 with the following command:

sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Adding the optional and extras repositories is also recommended:

sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update

Snap can now be installed as follows:

sudo yum install snapd

Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:

sudo systemctl enable --now snapd.socket

To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:

sudo ln -s /var/lib/snapd/snap /snap

Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
