Contents of README:This is version 2.5a of Snefru. Version 2.5a implements the same algorithm as Versions 2.0, 2.1, 2.2, and 2.3. Version 2.5a allows 8 passes, and includes the necessary tables for 8 passes. The use of 4 passes for production use is not recommended at this time. While 4 pass Snefru has not been broken as of 90.11.30, the use of additional passes seems advisable in view of the break of 2 pass Snefru. Snefru reads from the standard input, hashes whatever is read, and writes the hash result (in hex) to the standard output. While 2.5a has not been optimized for speed, it should provide reasonable performance. At the same time, the implementation should be relatively easy to understand. One C source file has been provided: snefru.c To compile, simply say: cc -o snefru snefru.c The shell script "testSnefru" is provided, along with the correct output values in "correctSnefruOutput". Simply execute testSnefru to test the hash function. To generate a version of Snefru that produces 256-bit output, say: cc -o snefru256 -DOUTPUT_BLOCK_SIZE=8 snefru.c To test this version, execute the shell file "testSnefru256". |
