Which specific error, "
'1address.....' is too long"? (
it's self-explanatory)
Vanitygen isn't a bruteforce tool, it's only for generating "
vanity" addresses.
for the format, something like this should work (
one per line):
1abc
1def
1ghj
1kmn
end
It seems vanitygen skips the last line so I specifically put "
end" there so it'll search all the prefixes.
