WebUsing the repeated squaring as mentioned in the other post: 38191 90043 ≡ 38191 ⋅ ( 38191 2) 45021. (all modulo n of course) We can compute the square of 38191 (modulo n) as 1125. So we need 1125 45021 which equals 1125 ⋅ ( 1125 2) 22510. Then 1125 2 = 57815 modulo n again. So we are reduced to finding ( 57815) 22510 = ( 57815 2) 11255 ... WebThese particular cryptographic methods convert plaintext into cyphertext, which needs a key to be decoded, from the input plaintext. The cryptography algorithm also creates this key. The encryption of a given plaintext will always be the same, as will the decryption key. Cryptography has 4 main objectives WebMar 17, 2016 · If the attacker knows the ciphertext and can correctly guess parts of the message (e.g. he knows it's a Windows executable, and therefore must start with MZ) he can get the corresponding key bits for the known range.
