salut,
je voudrais s'il vous plait un coup de main pour déchifrer un text crypté avec Vigenère!
voici les données:
le text:22, 11, 17, 4, 9, 11, 20, 1, 8, 12, 14, 17, 15, 11, 12, 3, 9, 18, 25, 6, 5, 21, 22, 17, 26, 6, 19, 3, 28, 24, 23, 7, 30, 4, 2, 24, 4, 19, 7, 13, 9, 4, 2, 14, 30, 29, 22, 22, 22, 18, 12 , 21, 4, 18, 9, 29, 2, 12, 2, 11, 6, 15, 8, 12, 30, 24, 20, 22, 12, 5, 22, 8, 7, 6, 23, 24, 24, 23, 15, 17, 18, 12, 5, 8, 0, 22, 30, 5, 28, 10, 24, 30, 11, 21, 0, 1

encryption is done modulo31
secret key of 6 letters was sent encrypted with Bob 's RSA public key in 2 groups of 3 letters:KV=899479,476285
(each number represents three leters)
Bob's public key:(N=1143343,E=5049)
the factors p and q of N must be recovered using Euler totient function Phi(N)=1141168
26 alphabet letters are already encoded as 2 digits number from 00 to 25
blanck encoded as 26
"," as 27
"." as 28
";" as 29
"?" as 30
Allah y5allikom wi berek fikom C urgent!!!!!!!!!!!!!
