You need to convert the 32 chars into 16 octects using hex2chr as shown here: http://www.hawkee.mobi/snippet/6505/ I don't know if its a limitation of the mIRC's language and its possible to > create md5 hashes with 16 chars in others more "professional" languages, or > I'm doing something wrong. > > > Waqas Hussain escribió: > >> On Thu, Feb 18, 2010 at 4:04 AM, IRcapmail <[email protected]> wrote: >> >> 2.
