Larger the database, more the words covered. Rainbow tables basically store common words and their hashes in a large database. Just go to one of the sites, submit the hash and if the hash is made of a common word, then the site would show the word almost instantly. Now a days hashes are more easily crackable using free rainbow tables available online.
So the greater challenge for a hacker is to first get the hash that is to be cracked.
Hydra does blind brute-forcing by trying username/password combinations on a service daemon like ftp server or telnet server. John the Ripper is different from tools like Hydra. Cracking password in Kali Linux using John the Ripper is very straight forward. Additional modules have extended its ability to include MD4-based password hashes and passwords stored in LDAP, MySQL, and others. It can be run against various encrypted password formats including several crypt password hash types most commonly found on various Unix versions (based on DES, MD5, or Blowfish), Kerberos AFS, and Windows NT/2000/XP/2003 LM hash. It is one of the most popular password testing and breaking programs as it combines a number of password crackers into one package, autodetects password hash types, and includes a customizable cracker. Initially developed for the Unix operating system, it now runs on fifteen different platforms (eleven of which are architecture-specific versions of Unix, DOS, Win32, BeOS, and OpenVMS).
