Changes:

*ver.2014.11.03*

- HiVE kernel module now defaults to a scheme based on AES-CTR to
generate randomness. The previous RC4-based scheme is still supported,
and can be enabled in the source code; however, it is shown to be
insecure (see the FAQ).

- Various bug fixes in the userland tool.

*ver.2014.07.29*

- Complete overhaul of key derivation. Now encryption key is generated
randomly, and password derived keys encrypt and store that key in the
headers.
- Complete overhaul of password verification. Now using a digest of the
master key stored in the headers.
- PBKDF2 no of iterations increased from 1,000 to 10,000.
- Better memory cleanup to erase all traces of passwords and keys.
- General bug fixes, corrections to usage parameters, naming
conventions, etc.
