Bringing to your attention that (for some years) there is a very small javascript crypto library. The site contains nice examples. For example, copy this paragraph into the "Verify" part of https://tweetnacl.js.org/#/sign as Message and add my public key, which is 6efE23aIqMLdkHj27fo1OJTt5VDyI/zx4eUcg9B7/3Q= and the next thing is the signature (which is obviously not part of the Message) which can be found on the following line.

Cryptography

From Greek κρύπτω krýpto "hidden" and the verb γράφω gráfo "to write" or λέγειν legein "to speak". Cryptography is the practice of establishing a secure connection between two parties in the presence of a third party whom you don't want to be able to read your messages. Cryptographers design algorithms and protocols, which do exactly this (and many other things). They also use a lot of time looking for security holes in existing protocols to make sure they can still be trusted. This is called cryptanalysis.
