type BufferPtr = AlignedBlockPtr BufferAlignment Prim Source #
additionalBlocks :: BlockCount ChaCha20 Source #
xchacha20Setup :: Nounce XChaCha20 -> Internals -> IO () Source #
The xchacha20Setup does the following to the internal state
- Replaces the key stored in the keyCell using the hchacah20 hashing function
- Initialises the ivcell with the last two words in the xiv value.
As a result the internal state is ready to start encrypting using the xchacha20 variant.
