In August 2025, NIST standardized a cipher small enough to run on a battery-powered sensor and simple enough to fit its whole state in five CPU registers. Learn how Ascon's sponge-based permutation delivers real authenticated encryption at a fraction of AES-GCM's footprint.
NIST's primary post-quantum signature standard works by signing, checking your own signature against a size limit, and throwing it away and starting over if it's too big. Learn how 'Fiat-Shamir with Aborts' turns a leaky lattice proof into a secure signature.
Falcon produces the smallest signatures of any NIST post-quantum standard — by solving a problem that broke the leading lattice signature schemes of the late 1990s/early 2000s. Learn the hash-and-sign paradigm, and why the naive version of it is fatally insecure.
Ever wondered how your data stays secure? Cipher Visualizers makes learning cryptography intuitive and engaging. We break down complex encryption algorithms into simple, interactive visualizations, allowing you to see the entire process flow from plaintext to ciphertext.
Watch algorithms like AES and RSA transform data in real-time. Follow every substitution, permutation, and key mix to truly understand the process, not just the theory.
Input your own custom data and keys. Pause, rewind, and inspect the state at any stage. See instantly how changing a single bit can affect the entire outcome.
Each visual step is paired with clear, concise explanations. Understand the "why" behind the math, not just the "how," with insights linked directly to the on-screen action.
