title: Find salt in the blowfish encrypted hash
body: <p>This is kind of very basic question. I have searched for help regarding this but couldn't find any concrete answer to it. Therefore i am asking it specifically here.</p>
  
  <p>The use case is, i want to find the weak password referring to the list of hashes available. For that i am have to compare the hash of each known/common words with the available hash. All this is done in C++ for Unix using openssl/blowfish.h</p>
  
  <p>However, to create the hash of this guess word needs to be generated using the same salt that was used for the password hashes. </p>
  
  <p>My question here is how can i extract the salt from password hashes. 
  Suppose, following is my hash:</p>
  
  <p>$2a$10$FTx8T5QrEbxYVe.NJ6iOhuei.V9qgl60xF8/8s7iZRDIlOl.ibDEW</p>
  
  <p>What is salt in this? or how i can achieve the goal? Any pointer would be great!!</p>
  
  <p>Thanks in Advance.</p>
