* I changed the CRC-24 checksum computation to include the coding parameter
K and the share number N so that these numbers are also protected.
If you have older shares generated with a previous version, you can still
decode the secret by simply removing the checksum part of the shares.
* The README now includes more information about the inner workings of
secretshare and also a note on "perfect secrecy".

# A word on the secrecy
Shamir's secret sharing is known to have the perfect secrecy property.

* `ssss` uses a hex encoding of the shares whereas `secretshare` crams
more bits into the characters via Base64.
* `ssss` does not add any checksums to the shares.
Note that the checksums are computed after the encoding of the shares.
They don't reveal anything about the secret. You still need K shares
to decode the secret and the checksums don't make it any easier to
brute-force anything. Their purpose is just to protect the integrity
of the shares.
