The output is written to a user-specified binary file.\n\nA pre-compiled executable for Windows machines is also provided.\n\n** Inputs\n\nThe command-line executable requires three parameters, in this order:\n\n1) The name of the file containing the DES key. This must be an 8-byte long hex file. See the file key.hex as an example.\n\n2) The name of the encrypted data input file. This must be a binary file. See the file test.hex as an example.\n\n3) The name of an output file. The cleartext results will be written to this file, as binary data. NOTE: This program will over-write (delete) any pre-existing file with the same name.\n\n   EXAMPLE:\n\n\u003edes_decrypt.exe key.hex test.hex output.hex\n\n** Miscellaneous\n\nThe provided test.hex file, when decrypted with the included key.hex file, will (properly) result in clear text of all zeros.\n\nNote that the included des_test_vectors.txt file contains DES test vectors. The files I provide (test.hex/key.hex) are the first decryption test vector.\n\n\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdelhatch%2Fdes_decrypt","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdelhatch%2Fdes_decrypt","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdelhatch%2Fdes_decrypt/lists"}
