 The file also contains intermediate values. A quick guidance with regards to its usage:
 
 - `valid.get_conversation_key`: calculate conversation_key from secret key sec1 and public key pub2
-- `valid.get_message_keys`: calculate chacha_key, chacha_nocne, hmac_key from conversation_key and nonce
+- `valid.get_message_keys`: calculate chacha_key, chacha_nonce, hmac_key from conversation_key and nonce
 - `valid.calc_padded_len`: take unpadded length (first value), calculate padded length (second value)
 - `valid.encrypt_decrypt`: emulate real conversation. Calculate pub2 from sec2, verify conversation_key from (sec1, pub2), encrypt, verify payload, then calculate pub1 from sec1, verify conversation_key from (sec2, pub1), decrypt, verify plaintext.
 - `valid.encrypt_decrypt_long_msg`: same as previous step, but instead of a full plaintext and payload, their checksum is provided.
