WebSo here we get 18a ≡ 12 (mod 2) and 18a ≡ 12 (mod13) or, reducing, 0a ≡ 0 (mod 2) and 5a ≡ 12 (mod13) The first is a tautology, and the second can be solved by multiplying by … WebCryptanalysis refers to the study of ciphers, ciphertext , or cryptosystems (that is, to secret code systems) with a view to finding weaknesses in them that will permit retrieval of the plaintext from the ciphertext, without necessarily knowing the key or the algorithm . This is known as breaking the cipher, ciphertext, or cryptosystem.
