A member of the MTC3 team informed me that hints are needed to solve this challenge – on the other hand it is unfair since 9 members already solved it.
So i will reveal only this information:
- The most frequent letter among the ciphertext is related to the most frequent letter in plaintexts – which is common to any of the four languages involved – which is actually "e".
- If the title of the challenge was "CAESAR CIPHER CHALLENGE" then the encryption key - DURING THE ENCRYPTION PROCESS - could be
I remind that repeating letters are omitted so if the word was MISSISSIPPI then the word should be
I believe this information is enough.
P.S. Many level 1 and 2 challenges are still unsolved by me and by many other members because authors think that the hints given are enough but they still remain unsolved for many time. I believe each author should balance if more hints are needed in order to encourage other members to solve it and on the same way to keep the level of the challenge as it is . . .
This comment was written because someone thought that this challenge should be level 2 despite he is among the top 10 in the HOL . . .
