I hope you have enjoyed the Black Chamber. If you have encountered any problems or have any ideas on how to improve the site then please let me know. You can also email me from here if you have any other questions or queries, although you might find that your question can be answered somewhere within www.simonsingh.net, so I would encourage you to explore that site first. There are lots of sub-sections, so have a look at the site map to help track down the relevant section.
 

If you can't find what you are looking for within the site, the links page at www.simonsingh.net may help. There are dozens of links to useful and interesting websites. For example, a particularly informative cryptography website is the RSA FAQ page.

If all else fails, then please feel free to e-mail me. In particular, it is great to hear from teenagers or children who have read my books, or seen my TV programmes, or who are just curious about science and mathematics. I look forward to hearing from you. I must warn you however, that the number of emails I receive is now so high that I am unable to find the time to answer all of them. I am genuinely sorry. I will still read every email, and I will try to answer the majority of them, but I can no longer guarantee that you will get a response. I hope you understand.

Please note that I have neither the time nor the expertise to crack coded messages and I cannot comment on any new cryptographic systems or methods for cracking RSA or proofs of Fermat's Last Theorem.
