The input to the bcrypt function is the password string (up to 72 bytes), a numeric cost, and a 16-byte (128-bit) salt value. The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form:
The table of HA1 values must therefore be protected as securely as a file containing plaintext passwords. [12] Digest access authentication prevents the use of a strong password hash (such as bcrypt) when storing passwords (since either the password, or the digested username, realm and password must be recoverable)
This is a list of reports about data breaches, using data compiled from various sources, including press reports, government news releases, and mainstream news articles.. The list includes those involving the theft or compromise of 30,000 or more records, although many smaller breaches occur continual
The bcrypt password hashing function requires a larger amount of RAM (but still not tunable separately, i.e. fixed for a given amount of CPU time) and is significantly stronger against such attacks, [13] while the more modern scrypt key derivation function can use arbitrarily large amounts of memory and is therefore more resistant to ASIC and ...
The attacker is free to choose a good price/speed compromise, for example a 150,000 keys/second design for $2,500. [ citation needed ] The key stretching still slows down the attacker in such a situation; a $5,000 design attacking a straight SHA-1 hash would be able to try 300,000÷2 16 ≈ 4.578 keys/second.

bcrypt is a password hashing function which, combined with a variable number of iterations (work "cost"), exploits the expensive key setup phase of Blowfish to increase the workload and duration of hash calculations, further reducing threats from brute force attacks.
