md5sum for vb net

[Gary Townsend]

Hey all i am looking to see if anyone has created a function or knows how to
create an md5sum that would match the md5sum routines found commonly in C++
and Linux.

Hi,

I believe this is what you are looking for.

Beware: MD5's lifetime as a useful hash is limited.

http://en.wikipedia.org/w/index.php?title=MD5

"Because MD5 makes only one pass over the data, if two prefixes with the
same hash can be constructed, a common suffix can be added to both to make
the collision more reasonable. And because the current collision-finding
techniques allow the preceding hash state to be specified arbitrarily, a
collision can be found for any desired prefix. All that is required to
generate two colliding files is a template file, with a 128-byte block of
data aligned on a 64-byte boundary, that can be changed freely by the
collision-finding algorithm."

Re: md5sum for vb net

:) thank you basically what i was doing was trying to write a program that
mimmiced BattleField's 2 CD Key Hash which from what i have heard is just
an md5sum of your CD Key.

IF i were to use a hash i will defienitely keep your link in mind thank you
