1. 8-28-18: We discussed our syllabus and syllabi in general, then introduced the Cipher Chain Challenge before finally discussing the Fall 2018 Semester Opener. Try to finish deciphering the opener for Friday.
2. 8-31-2018: We covered most of Chapter 1 Section 1 in Cryptology Through History and Inquiry, try to finish that for a quick discussion at the start of class Tuesday.
3. 9-4-2018: We had the syllabus quiz and finished up chapter 1 section 1.  Read through chapter 1 section 2 in CT&I so that we can move through it smoothly Friday.

6. 9-14-2018: We had our first exam today and you all did great, 100%’s all around for those who were there.  (But remind me on Tuesday to talk about shift ciphers)
7. 9-18-2018: We started unit 2 by looking at the first section of chapter 2 in Cryptology Through History and Inquiry.  In particular we discussed qualitative and quantitative properties of language.
8. 9/21/2018: We talked about the John Falconer and started reading through his commentary on frequency analysis.  We will continue this, be sure to find a large sample of plain text that we can use throughout this unit to more closely examine the ideas we discuss.
9. 9-25-2018: We talked about strategies for reading text for details.  Then, we spent the rest of the class talking about Falconer’s second step in analyzing language.  We will look at steps 3 and 4 on Friday and try some examples.
10. 9-28-2018: We had the reading and vocabulary quiz and finished looking at Falconer’s recommendations for decryption.
11. 10-2-1018: We spent class practicing cracking ciphers. Here is a copy of the ciphers we looked at in class, you should try finishing them on your own.  Additionally you should look at problems 5, 6, and 7 from the end of chapter 2.  Finally, I added a sample deciphering as an appendix at the end of the online text.
