ocra_debug is an OCRA implementation with detailed errors descriptions. Use it for debugging purpose only! For production code use ocra function.

suite is a value representing the suite of operations to compute an OCRA response;

key is a secret, previously shared between client and server;

counter optional synchronized between the client and the server u64 counter;

question mandatory challenge question(s) generated by the parties;

password optional ALREADY HASHED value of PIN/password that is known to all parties during the execution of the algorithm;

session_info optional information about the current session;

num_of_time_steps optional number of time steps since midnight UTC of January 1, 1970; step size is predefined in the suite;

Example

extern crate oath;

use oath::ocra;

fn main () {
    let suite_c = "OCRA-1:HOTP-SHA256-8:C-QN08-PSHA1";
    let STANDARD_KEY_32 = b"12345678901234567890123456789012";
    let PIN_1234_SHA1 = &[0x71, 0x10, 0xed, 0xa4, 0xd0, 0x9e, 0x06, 0x2a, 0xa5, 0xe4,
