Thanks a lot for the clarification. I have checked the supported algorithms for oclHashcat, which is my final goal as I need to crack a 15 characters ?l?u?d password (thus I started to practice the base Hashcat on an Amazon EC2 instance).

This page mentions HMAC-Ripemd-160:
"TrueCrypt 5.0+ PBKDF2 HMAC-RipeMD160 + AES"
Based on your experience, the fact that my file was created with an unsupported Truecrypt makes it useless for oclHashcat, even if the algorithm could be supported?
I know the natural answer is "just try", but I fear I do not know enough yet to move on to the more advanced oclHashcat.
