One more time you saved me SL :)

 all is fine, even hash + salt (with a second "$" in the salt, are 
cracked correctly, for example 
"user[tab]md5_gen(7)c81c3cf3fb69d77afe5e7c11b2ec19a8$ek$"

 Is md5_gen(7) able to handle salt with more 3 characters (for example 
IPB2 has salt with 5 characters) ?

 thanks.
