CipherLock is a minimalist interactive hub to explore cryptography. Features Caesar, Vigenère, Morse, Atbash & Rail Fence ciphers. Includes an Academy for foundations and a Daily Enigma challenge. 100% client-side, open source & privacy-focused.
I’m a Computer Science student currently writing my final thesis on cryptography. I created CipherLock because I couldn’t find a hub that balanced technical rigor with a modern, didactic interface.
I treat this as a living laboratory. It is an ongoing project with weekly updates, I’m constantly shipping new ciphers, interactive modules, and deepening the "Academy" section.
Highlights: - Formative Academy: Focuses on the 'why' and 'how' of historical and modern encryption systems. - Brutalist DNA: A raw, field-manual aesthetic designed for clarity and technical speed. - Client-Side Security: All mathematical logic runs strictly within your browser.
Since I am iterating on the code every week, your feedback directly shapes the next update. Let me know which cipher or concept you would like to see visualized next.
Learning by breaking things is genuinely the best way to understand security. Does it start easy or throw you in the deep end immediately?

Who hunted CipherLock?
CipherLock was hunted by Rafael Sampaio. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
