Unfortunately, there is no way to directly brute force passwords protected by PBKDF2 or BCrypt. These algorithms are designed to be extremely secure and resistant to password cracking attacks. The best way to crack these passwords would be through a brute force attack with a very large password guess list, which is essentially impossible given the computing resources necessary.

The most effective way to develop an algorithm to crack passwords protected by PBKDF2 or BCrypt is to use a version of the original password-cracking techniques combined with additional speed improvements. This can be accomplished by leveraging parallel computations, clever bit-sorting algorithms and optimized hashing methods. In order to efficiently brute force passwords, dictionary passes and other specialized tests should also be run.
In addition, one can deploy advanced statistical attacks and attacker models that explore different parts of the key space in order to detect likely candidate keys and increase the rate of success. Furthermore, it may be possible to utilize certain features provided by the operating system – such as NTLM Authentication or Access Tokens – which often provide critical information useful in identifying valid users or credentials related them. Finally there are a variety of tools available for automatic password analysis for assistance with various steps required for brute forcing attacks - these range from rainbow tables (which allow direct search on salted hashes) that have previously hashed plaintext password candidates up through more sophisticated cloud–based offerings aimed at enterprise clients attempting to locate valid credentials quickly during security audits; however no matter what methodology is employed great caution should always taken so as not unduly expose one's system!
