i use this code to get the MD5 hash of a file (extracted from this post)
[code]dim mdfive as new MD5Digest
dim bs as BinaryStream = BinaryStream.Open( f )
while not bs.EOF
dim chunk as string = bs.Read( 1000000 )
dim hash as string = EncodeHex( mdfive.Value )[/code]
how do i get the sha-256 value from a file?
