Perhaps you meant "encrypt" instead of "hash" since hashes are one-way and I'd assume you want to decrypt it sometime.  If so, then here is a link that describes hot to accomplish that.

Yes, that's what we need, one-way.  We hash sha1 the result save it to table.

Can this be done in vb6?

in the event that code proves to be faulty, search the internet for this phrase...

Thanx!!! Found a code thet works excellent and we compared it to MS SQL HASHBYTE function is almost the exact!

We say exact because the SQL function always returns "0x" when the vb code doesn't.

For example the has for 'experts-exchange' in

vb6 code is:             9022fc0e1985bb7c0ac60792ee3fbe3029af0424

in SQL is:                 0x9022FC0E1985BB7C0AC60792EE3FBE3029AF0424

                                 notice "0x"

We extract the "0x" from SQL statement result and both SQL & VB results are the same.

Is there a reason for the "0x" and should we be concerned?

yes, that is not actually a part of the hash.  It is there to signify that the remaining characters are hexidecimal. It is safe to just strip it off as you did.
