Install: brew install truecrack

About:
Truecrack is a command-line utility designed to perform dictionary-based brute-force attacks against TrueCrypt encrypted volumes. It optimizes the password cracking process by leveraging GPU acceleration via CUDA, significantly increasing the speed of key derivation compared to CPU-only tools. This allows security professionals and auditors to test the strength of their encryption passphrases against common attack vectors.

Key Features:

GPU-accelerated password cracking using CUDA
Support for TrueCrypt volumes and partitions
Dictionary attack mode for efficient guessing
Command-line interface for scripting and automation

Use Cases:

Auditing the password strength of TrueCrypt encrypted data
Recovering lost passwords for encrypted volumes if the password is within a known wordlist
Educational purposes to understand encryption vulnerabilities

Alternatives:

John the Ripper – A more comprehensive password cracker that supports TrueCrypt via community patches, but lacks the specific GPU optimizations for TrueCrypt found in Truecrack.
hashcat – A highly advanced password recovery tool that supports many hash types; however, Truecrack is specialized specifically for the TrueCrypt KDF.
