Structure

Files are organized in different subfolders, as follows:

• snippets/: Stand-alone source code files that can be compiled with make.
• programs/: Stand-alone programs and software as designed during the online course.
• executables/Win: Pre-compiled executable files for WINDOWS operating system (.exe).
• executables/Linux: Pre-compiled executable files for Linux operating system (.bin).
• executables/MacOS: Pre-compiled executable files for MacOS operating system (.bin).

Outline

Some of the most advanced cryptographic concepts are implemented in smaller programs distributed with this repository. Following table lists some of the most prominent programs in this repository:

Program	Description
NextVersion	A C++-language updates and version features tester utility.
ROT13	Implementation of the ROT13 algorithm using the standard library.
Randomizer	Uses random number generators to generate 32-bytes random bytes (Crypto++).
Caesar++	A digital remake of the popular Caesar Cipher from 2000 years ago (Crypto++).
Curvy++	Elliptic curve cryptography with ed25519, secp256 and PKCS1 (Crypto++).
CryptoStars	Mastering Crypto++: ECDSA, AES, ECDH, ChaCha20 and ROT13 (Crypto++).
Flowers	A minimal implementation of Camellia encryption/decryption (Botan).
Handshaker	A handshake-only implementation of TLS communication channels (Botan).
BeeTransport	A more elaborated use-case for symmetric encryption with Camellia (Botan).
SecretMaker	A simplistic Makefile with RSA keys, AES encryption and ECDSA signatures (Botan).
WhatBlock	Encryption block-by-block using block ciphers: AES, ARIA, Blowfish, and others (Botan).
SymmetryRace	A race between Symmetric- and Asymmetric Encryption Algorithms: AES vs. RSA (Botan).
Siggie	A DSA command line utility featuring secp256, sign documents using ECDSA (Botan).
HTTPSafe	An example implementation for TLS channels over HTTP to configure HTTPS connections (Botan).
SMS++	An asynchronous authenticated messaging system using ECIES system and ECDH (Botan).
Whispers	An end-to-end encrypted offline chat using ECIES system, ECDH and ephemeral keys (Botan).
ZThanks	A pot-pourri of Botan and Crypto++ integrations with: AES, SHA-256, ECDSA and ECDH.
