I don't think specifying the encryption scheme makes any sense except in some rare cases where you really know what was used. Trying all the encryption schemes is quite feasible as that happens much faster as compared to the key strengthening part. Worst part though is that you have to try all the three key strengthening algos - PBKDF2 with sha512, whirpool and ripemd160. Since likely most of the volumes use the default sha512 one, I guess the sha512 support itself would suffice at least initially.
