how to crack md5(md5(pwd)+string) hashes? - perlish - 06-28-2012
hi,the hash was created using md5(md5(pwd)+string),how can I use plus to crack it ?
thank you !

This depends on string length. If salt length < 30, use 2611. if its 30 use 2711. Otherwise its not supported.

md5(md5(pwd+string)) means md5(md5(pwd.salt)) ?
it seems 2611 and 2711 did not work,double md5 seems ok but can not crack.

md5(md5(pwd)+string) != md5(md5(pwd+string))
also you did not specify that "string" in your hash file (aka salt).
