Masked Attack Parameter for Binary

[DaBomb]

How do I do a mask attack on a binary string that is hashed with MD5? 

So for example...

String:
test word spaces

Binary:
01110100 01100101 01110011 01110100 00100000 01110111 01101111 01110010 01100100 00100000 01110011 01110000 01100001 01100011 01100101 01110011

MD5:
5c61957f8dcf9360f3f996cb689608ba


String > Binary > MD5
