CRC32

Hello,
I am looking for a VB.NET routine (code reuse) to calculate a CRC32.
Many thanks for your help.

You could probably write your own by starting here:

Re: CRC32

Hi,

There are many variations on CRC32 (two or three are popular, but many
others are in use "somewhere" ). You need to specify what algorithm is being
used. For example the CCITT CRC32 (probably) is the most popular.

I have source code examples for two variations in my book (see below), but
perhaps this will suit your needs:
