Does the windows version of Snow also decrypt this? I can't install Java because apparently Sun is hosting corrupted files.
Yes it does.
the file, where the text is encrypted, is:
if the password string is the following:
this is the password phrase[/list:u]
then you will get the right solution with the "DOS/Windows executable" from the site given in the challenge (i used the "32-bit executable"):
snow -C -p "this is the password phrase" "snow.txt"i hope this helps.
