@@ -17,7 +17,7 @@ BTP uses the following cryptographic primitives:
 
 All keys are key_len bytes and all nonces are nonce_len bytes. The output of MAC(k, m) is mac_len bytes, and the output of ENC(k, n, m) is auth_len bytes longer than m. For simplicity we require that mac_len == key_len.
 
-> Implementation note: The previous version of BTP used HMAC-SHA-256 as the pseudo-random function and AES-256-GCM as the authenticated cipher. The next version will use BLAKE2s as the pseudo-random function and XSalsa20-Poly1305 as the authenticated cipher. In both cases, key_len == 32, mac_len == 32, nonce_len == 24, and auth_len == 16.
