Phantom Cipher Description

Phantom Cipher is a block cipher software. Phantom Cipher is a block cipher software. The rundown: it has a block length of 128 bits, and a key size of 256 bits. A detailed description of the cipher is in the README file in the package. One of these days I will turn it into an HTML document.The distribution contains an implementation of a file encryption utility (that currently compiles only on POSIX systems due to the platform-specific way it gets the password without echoing.) The phantom library is well rounded: it has a hashing function for producing keys from pass phrases, as well as encryption and decryption functions that operate Phantom in each of the three important modes: ECB, CBC and CFB.Installation:Compilation of the C sources requires an implementation of ANSI/ISO C.Compilation of filecrypt.c additionally requires a POSIX.1 implementation.There will be difficulties compiling the sources on outdated UNIX versionswhose bundled compilers don't support ANSI C or which don't have POSIX.1 or ANSI C compliant libraries.The Makefile assumes that you have the GNU C compiler. Edit the Makefile as appropriate and then type ``make''. An executable called ``phantom'' should result. This is the UNIX utility for enciphering and deciphering files.To use Phantom in existing ANSI C programs, simply copy phantom.c and phantom.h into the directory where your project resides. Include the phantom.h header file in any translation unit which needs to refer to a Phantom function or data type. Compile and link the phantom.c file along with the other source files of your project.The filecrypt.c program may serve as a programming example.The phantom.c also contains a main() function for testing purposes. This is enabled by defining the TEST_MAIN preprocessor symbol prior to compiling phantom.c.To encrypt:phantom -e ] ] ]to decrypt:phantom -d ] ]
