README

          
This package adds enhancements to Go's implementation of Galois counter mode

authenticated encryption. Specifically, it adds two features: online encryption,

decryption, and verification (meaning the operation does one pass of the

plaintext or ciphertext), and the ability to efficiently "fast-forward" the key

stream so as to facilitate random access of the ciphertext.

Much of this code comes from the Go project; see LICENSE in this directory for

terms of use. For a summary of changes, have a look at:

TODO(cjpatton)

  * Change TagSize() to Overhead() in AEADEncryptor and AEADDecryptor interfaces.

  * Improve test coverage. (The original code does not have test vectors for

    extended nonces.)
