As a cryptanalyst, you are able to acquire the following ciphertext, along with some known plaintext as indicated. Encryption is based on the Hill cipher using blocks of 2 characters over Z26 synchronized so that the first 2 ciphertext characters are a block. (Note that spaces, punctuation, and capitalization are removed from the plaintext.) pfpzmypfside pinorqecfmfyu w ciphertext plaintext S f i a f Determine the decryption key and the encryption key. Decrypt the first 14 letters and guess the rest of plaintext. (HINT: For some data combinations it may not be possible to determine a unique solution when solving equations. If you find this to occur, use other data combinations in your analysis.) As a cryptanalyst, you are able to acquire the following ciphertext, along with some known plaintext as indicated.
