Truecrypt v1.0 525kbs
Truecrypt v2.0 502kbs
I am looking for Truecrypt v1.0 (after this version truecrypt no longer supported Windows 98 or ME). Truecrypt is published under a GPL license so I don't think it is a problem to put the 1.0 version on this site. See http://www.truecrypt.org/ for more details about the program.
