I have added a crypto page
Partly, I am experimenting with pages for wordpress blogs. And, partly, I have made enough crypto posts that I should collect them together. So, for now, I have added a crypto page. There should be a link in the header of blog pages.
For the present, the new page is a work in progress. Initially, it consists of links to several blog posts on encryption. However, some of those older posts need updating, so I will probably move the updated information to the crypto page (or a sub-page). That will provide a more stable url for information that needs occasional updating.
