Cryptography

Full Title

General resource site for Cryptography.

Context

• Cryptography originally meant Secret Writing and was use by Caesar in his communications from the Gallic wars. Since then it has become a category of mathematics dealing with methods that are easy to invoke and difficult to discover. Commercial Cryptography is involved in:

1. protecting data from disclosure (its original purpose) and
2. assuring the source or integrity of messages.

• Specific details are on the wiki pages Secret Key Cryptography and Public Key Cryptography.

Problems

• Cryptography is hard math that deals with the solution of hard problems. It is not a topic that can be addressed by programmers looking for simple solutions with a limited time budget.

Solutions

Most programmatic solutions are not sufficiently robust to fend off attacks by determined adversaries.
