To find a one-way hash function

P: n/a
Hi! I am doing a project...for what I need one way hash function....

Actually I need to compress a 64-bit binary data into smaller one by a
systematic method....

So how do I do that? The user should not be able to retrive tha data
from the compressed one ....

so I am thinking for trying it with one way hsh function......

But I dont know which algo should I use? Should I use MD5? or some
other things..
Thanks for those who answer.......

unsigned long super_compress ( unsigned char const * buffer ) {
return 0;
}

Does not compress as well as the above. Also, might leak more information
about the compressed data.

Actually, you are way off-topic. Please read the FAQ and the Welcome post
for what is discussed here and what belongs elsewhere.
