Re: [Cfrg] I-D Action: draft-irtf-cfrg-chacha20-poly1305-00.txt

I note that there is a repeated error in the HEX <-> ASCII conversion for the test vectors that use the phrase "'Twas brillig, and the slithy roves…”:
 - A.2, Test Vector #3
 - A.3, Test Vector #4

I can verify the test vectors using the hex plaintext, but this is not representative of the actual text.
Specifically all but the last period (ASCII 0x2e) in the text are 0x0A in the hex representation.

The error is also in draft-nir-cfrg-chacha20-poly1305.
