“The settlement agreement falls within the range of possible approval as fair, reasonable, adequate, and in the best interests of the class,” U.S. District Court Judge Edward Davila in the Northern District of California wrote in an order issued on Thursday. Davila's order only grants the deal “preliminary” approval, meaning that he could still reject the settlement after a final hearing.

For example, if a person's password is "Rover" the SHA-1 hash would be "ac54ed2d6c6c938bb66c63c5d0282e9332eed72c.

" Converting those hashes into their original passwords is possible using decoding tools and powerful graphics processors.
