crypto: testmgr - Add ChaCha20 test vectors from RFC7539
Browse files Browse the repository at this point in the history 
We explicitly set the Initial block Counter by prepending it to the nonce in
Little Endian. The same test vector is used for both encryption and decryption,
ChaCha20 is a cipher XORing a keystream.
