Internet-Draft Test Vectors for the Stream Cipher ChaCha October 2013
1. Introduction
The ChaCha [ChaCha] algorithm is a fairly new stream cipher that is
getting some attention. ChaCha has been proposed as a replacement
for RC4 [RC4] and ChaCha is also used in a few protocols.
In order to efficiently implement the algorithm and ensure
interoperability between different implementations, it is of great
importance to be able to verify that a given implementation is
functionally correct. Test vectors aids this verification by
providing a known correct answer.
Unfortunately, for ChaCha there are no test vectors published. This
Internet Draft tries to rectify this by providing test vectors for
ChaCha.
2. Description of the test Vectors
The test vectors describes in this document is given as a number of
test cases. For each test case there is a number of test vectors and
known answers. The test vectors in a test case has been generated
with support for:
128 and 256 bit keys
8, 12 and 20 rounds
This means that for a given test case there are 6 different test
vectors. Each of these test vectors contains the keystream for two
64 byte blocks.
The test vectors in this I-D has been generated by a simple generator
based on the chacha.c [chacha.c] reference model by Daniel J
Bernstein. The generator has been verified to generate the same
values as the reference model. reference model.
All zero input data blocks, that is 64 bytes with the value of 0x00
has been used during generation. Since ChaCha is a stream cipher and
encryption, decryption is done by XOR-ing the data with the
keystream. By using all zero data blocks we get the keystream
itself.
The random key in Test Case 8 has been generated by the following
command. For 128 bit key only the first 16 bytes are used.
$ echo -n "All your base are belong to us" | openssl dgst -sha256

Internet-Draft Test Vectors for the Stream Cipher ChaCha October 2013
The random IV in Test Case 8 has been generated by the following
command. Only the first eight bytes are used.
$ echo -n "Internet Engineering Task Force" | openssl dgst -sha256
1ada31d5cf688221c109163908ebe51debb46227c6cc8b37641910833222772a
The test vector generator is available as a stand alone c program in
the chacha_testvectors [chacha_testvectors] project on Github.
