8ed3bff6db Cleaned up chunk header encoding during encrypt/decrypt. 
* encrypted chunk header now encodes _only_ plain text length
* the AEAD tag length is implicitly added when reading/writing
* added better sanity checks for short blocks during decrypt
* io.ReadAtLeast() reports ErrUnexpectedEOF for less than a full chunk;
  use this signal correctly
* major version bump to denote header incompatibility

f32525a864 THIS IS A BREAKING CHANGE! Private Keys generated by previous versions won't work with this version. 
* Refactored the private key protection to use standard AEAD
  construction.
* Fix sanity check of decrypted block length to stay within verified
  bounds
* Cleanup test harness to split into utility file (assert()); cleaned up
  names of test functions.
* Fixed scrypt params to not take too long (N=2^19)
* Updated README with these changes

* Added support to read openssh public keys and encrypted private keys
* reworked private key handling
* made password the default; generating keys without password
  requires explicit "--no-password"
