BCrack: Bcrypt Hash Crackerr

This C program prompts the user for a file path to a wordlist containing potential passwords and a bcrypt hash to crack. It reads each password from the wordlist, generates a bcrypt hash for each password, and compares it with the provided hash. If a match is found, it prints the password. The program assumes the presence of bcrypt-compatible hash and uses the crypt() function for hash generation. If successful, it terminates after finding the password.

Requirements

• Clang compiler
• Make
• Linux environment (due to the use of <unistd.h> for crypt)

How to Use

1. Compile the Program:

make bcrack

2. Run the Program:

./bcrack

3. Follow the Prompts:

• Enter the path to the wordlist file containing passwords to test.
• Enter the bcrypt hash that you want to crack.

4. Outcome:

• The program will read each password from the wordlist, generate its bcrypt hash, and compare it with the provided hash.
• If a matching password is found, it will be displayed.

Example

$ ./bcrack
Enter the path to the wordlist: example_wordlist.txt
Enter the bcrypt hash to crack: $2a$12$g/Ee8Hm1g1/5spm2V733euokwUNVkOYqLvX8YPCcYBIQohj79L5KO
Password found: 123456
