I am sorry for partial definition of problem. I have MD5 hash computed
from string,
where is every character from plain-text password padded by NUL
character (hex 00).
So, string "password" (70 61 73 73 77 6F 72 64) is padded to
"p a s s w o r d " (70 00 61 00-73 00 73 00-77 00 6F 00-72 00 64 00) and
from this string is computed md5 hash - b081dbe85e1ec3ffc3d4e7d0227400cd.

Thanks to W.A. for hint, I will try JtR with modified charset and if
it will not work,
then last way is modified source code of JtR.
