CRC decryption I have a generated Hex CRC code, based upon a hexadecimal 16 character sequence. I need to find the polynomial that generates the CRC to generate new CRCs with my own 16 character sequences. I have 3 example instances of the characters and the resulting CRC. Once verified working, the second separate project may be creating a simple application to generate the CRCs. 19 Delphi, Matlab and Mathematica, Cryptography, CUDA, Prolog Feb 16, 2017 Feb 16, 20173d $2005
Writing a code Encryption Decryption program Write a program in any language you wish that accepts plaintext, a password (either through prompting the user or on the command line), and whether to encrypt or decrypt. Your program should, if available, use AES with a 128 bit key (derived from the password) in ECB mode to either encrypt or decrypt the plaintext given by the user. If AES-128-ECB mode is not avail... 23 C Programming, Java, Cryptography Feb 16, 2017 Feb 16, 20172d 18h $48
