Dorabella's cipher is the name given to a message sent by composer Edward Elgar dated July 14, 1897, in a letter to Dora Penny. The message takes the form of 86 characters (with 24 distinct characters) written on 3 lines:
The 24 characters and their distribution (based on frequency analysis) are compatible with encryption by mono-alphabetical substitution. Edward Elgar never disclosed the original message but would have described his alphabet and substitution table as follows:
Other alphabets have been proposed but this message has never been clearly decrypted even if several people have tried various translations, none has convinced the community.
The presence of a dot near the end of the first line is sometimes considered to be an 87th character (and therefore 25 distinct)
Dorabella symbols are arc/semicircles/halfcircles assembled by 1, 2 or 3 and oriented in 8 directions ↑ ↗ → ↘ ↓ ↙ ← ↖
All references to Edward Elgar or Dora are clues.
The original message is dated July 14, 97 (for 1897)
