From 961c30f7172228bbee84eefa6aaeb24f0c1a35e6 Mon Sep 17 00:00:00 2001 From: Robin Krahl Date: Thu, 5 Apr 2018 00:36:04 +0200 Subject: Correct documentation for NK_write_{hotp,totp}_slot While the actual secret is 20 bytes, the functions accept a hex string. That means that every byte of the secret is represented by two bytes (characters) in the hex string. So the argument secret for the functions NK_write_{hotp,totp}_slot is char[40], not char[20]. --- NK_C_API.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/NK_C_API.h b/NK_C_API.h index 96a1950..3bcff00 100644 --- a/NK_C_API.h +++ b/NK_C_API.h @@ -212,7 +212,7 @@ extern "C" { * Write HOTP slot data to the device * @param slot_number HOTP slot number, slot_number<3 * @param slot_name char[15](Pro) desired slot name - * @param secret char[20](Pro) 160-bit secret + * @param secret char[40](Pro) 160-bit secret as a hex string * @param hotp_counter uint32_t starting value of HOTP counter * @param use_8_digits should returned codes be 6 (false) or 8 digits (true) * @param use_enter press ENTER key after sending OTP code using double-pressed scroll/num/capslock @@ -229,7 +229,7 @@ extern "C" { * Write TOTP slot data to the device * @param slot_number TOTP slot number, slot_number<15 * @param slot_name char[15](Pro) desired slot name - * @param secret char[20](Pro) 160-bit secret + * @param secret char[40](Pro) 160-bit secret as a hex string * @param time_window uint16_t time window for this TOTP * @param use_8_digits should returned codes be 6 (false) or 8 digits (true) * @param use_enter press ENTER key after sending OTP code using double-pressed scroll/num/capslock -- cgit v1.2.1
