cryptopals

These are my solutions to the Cryptopals Crypto Challenges.

Structure

Solutions for set X are located in src/setX/*.cpp. Common library code is located in src/*.cpp, with the corresponding headers in src/*.hpp. Each challenge is implemented as a single function in its source file, with the main function in that file providing a test case.

Dependencies

• make
• gcc or clang
• valgrind
  • Available on Linux and macOS Sierra 10.12 and below
• openssl

  • On Linux, the headers should already be included in /usr/include/openssl.

  • On macOS, the headers can be installed with brew:

    $ brew install openssl
    $ cd /usr/local/include/
    $ ln -s ../opt/openssl/include/openssl .
    

Building

To build the solutions:

$ make all

To build the solutions with debug symbols:

$ make debug

The resulting object files, libraries, and binaries are placed in the build/ directory.

Testing

To run tests:

$ make test

To run the tests with valgrind:

$ make valgrind
