Patched dd with Computer Forensics Features

dc3dd is a patched version of GNU dd to include a number of features useful for computer forensics. Many of these features were inspired by dcfldd, but were rewritten for dc3dd. * Pattern writes. The program can write a single hexadecimal value or a text string to the output device for wiping purposes. * Piecewise and overall hashing with multiple algorithms and variable size windows. Supports MD5, SHA-1, SHA-256, and SHA-512. Hashes can be computed before or after conversions are made. * Progress meter with automatic input/output file size probing * Combined log for hashes and errors * Error grouping. Produces one error message for identical sequential errors * Verify mode. Able to repeat any transformations done to the input file and compare it to an output. * Ability to split the output into chunks with numerical or alphabetic extensions
