Yes while some challenges overlap, we also explore more deeply the mathematics of cryptography, as well as its practical use in protocols like TLS. We recently added challenges on lattice-based post-quantum cryptography. In this way it makes a great complement to CryptoPals.
But it's not all harder, our introductory section gradually introduces concepts like base64 encoding and the modulo operator one challenge at a time.
