Detailed explanation-1: -Bcrypt, scrypt, and PBKDF2 are all examples of key stretching algorithms.

Detailed explanation-2: -PBKDF2 prevents password cracking tools from making the best use of graphics processing units (GPUs), which reduces guess rates from hundreds of thousands of guesses per second, to less than a few tens of thousands of guesses per second.

Detailed explanation-3: -BCRYPT: BCRYPT is a password-hashing algorithm based on the Blowfish cipher. PBKDF2: PBKDF2 stores passwords with a random salt and with the password hash using HMAC; it then iterates, which forces the regeneration of every password and prevents any rainbow table attack.
