PDF Editor FAQ

The decryption is clearly AMBIDEXTROUS: Encoded by the following matrix: YDGBN AMUTO QSCHI VXKFE WRLZP or perhaps ABSORPTIVELY: VKXQP TGFHO YCRSN BWZUD MLIAE or the similar ADSORPTIVELY: DUSNR TWHOF VZQPX MALEI YKCBG or BRACHYLOGIES: SCHAN GTPQD LZKWF MEIBO RVXUY or CELIDOGRAPHY: VIPSQ RHMYC FLGWZ DNEBU XOAKT or DISCOVERABLY: TCYHQ DLMRB WKAGP ZVEFX UNISO I could come up with more if you like.
Is it possible to decrypt a Playfair Cypher without knowing the key and plaintext? If yes then how?
Please refer to the Wikipedia article: Playfair cipher sub section Cryptanalysis.Quote: "When only the ciphertext is known, brute force cryptanalysis of the cipher involves searching through the key space for matches between the frequency of occurrence of digrams (pairs of letters) and the known frequency of occurrence of digrams in the assumed language of the original message."
Cryptography: What advantage does a 25 character cypher have over a 26 character one?
A2A. The only advantage I can think of is one that applies to older, manual ciphers - a 25 character cipher can be put into a 5*5 grid, so it can be used for a Playfair cipher or other such grid-based ciphers.Lyon Playfair - he promoted the cipher, Wheatstone invented it.As far as which character is omitted - the Playfair "usually omitt[ed] "Q" to reduce the alphabet to fit; other versions put both "I" and "J" in the same space". You could omit/combine anything you like, buta) you want to make it easy for people to reconstruct the message - since 'I' is a vowel and 'J' is a consonant, by context jt's clear whjch js jn need of adiustment.b) you want to make it easy for humans, so picking letters that are close to each other (like 'I' and 'J') is an advantage. Similarly, 'Q' is very rare, unless you are quarreling with Quebec, Qatar, or Qom, in which case you might want to pick a different letter to omit :).
