[Tcllib-devel] question from the wiki

[Virden, L. W. <lv...@ca...>]

Over at http://wiki.tcl.tk/18004 , I noticed this question:

package require blowfish

puts "[blowfish::blowfish -dir decrypt -key STNkeySTNkeySTNk [binary format H* [blowfish::blowfish -hex -dir encrypt -key STNkeySTNkeySTNk muukav]]] hohoho"

same example in a more readable way:

set pw [blowfish::blowfish -hex -dir encrypt -key STNkeySTNkeySTNk muukav]

puts "[blowfish::blowfish -dir decrypt -key STNkeySTNkeySTNk [binary format H* $pw]] hohoho"

Why does these only return muukav and not muukav hohoho? RS: Maybe the blowfish::blowfish result has extra \NUL bytes at the end? Tcl can stand that, but puts might terminate at a NUL byte.

Anyone an expert on blowfish?
