I just uploaded a new paper to The Chaocipher Clearing House entitled "Chaocipher Revealed: Decipher Exhibit #1". The paper is an in-depth analysis of Byrne's Exhibit #1, discussing such topics as:
  • The textual layout of Exhibit 1
  • What is the challenge for the cryptanalyst?
  • Chaocipher as a known-plaintext / known system problem
  • The starting alphabets
  • The full deciphered plaintext
  • A discussion of the deciphered plaintext, including unanswered questions
  • Errata observed in Exhibit 1 as presented in "Silent Years"
  • How Byrne generated the starting alphabets
  • A discussion of Byrne's intended cryptographic indicator system
  • Numerous references to related topics
Enjoy!

I've heard of the pangram before but not the ending "TOSAVETHEIRPARTY".
