We'd love to hear from you.
Cipher Visualizers is an independent project, and every article and visualizer on it can always be more accurate or more useful. If you've spotted a mistake, hit a bug, or want to suggest a topic, the form below reaches the person who actually maintains the site.
Frequently Asked Questions
What kinds of messages are a good fit for this form?
Corrections on an article (a wrong date, a misstated fact, a broken link), bugs in one of the interactive visualizers, suggestions for a cipher or algorithm we haven't covered yet, or general questions about the cryptography topics on this site. If you're just curious about something you read, ask away.
I think I found an error in a guide. What should I include?
The article's title or URL, the section or paragraph it's in, and what you think is wrong (with a source, if you have one). Specific reports like that are easy to verify and fix quickly; "something on the RSA page is off" is much harder to act on.
A visualizer isn't working the way I expect. What's useful to mention?
Which visualizer, what you entered, what you expected to happen, and what happened instead. Screenshots help. If it's browser-specific, the browser and OS are useful too.
How long does it take to hear back?
Cipher Visualizers is an independent project run by one person, not a support team, so replies aren't instant. Genuine corrections and bug reports get read and acted on; please don't expect a guaranteed turnaround.
Is this the right place to report a security issue with the site itself?
Yes. Describe the issue clearly in the message below and we'll look into it.
