============================================

Synopsis
--------

*#include <ngtcp2/ngtcp2_crypto.h>*

.. function:: int ngtcp2_crypto_generate_stateless_reset_token( uint8_t *token, const uint8_t *secret, size_t secretlen, const ngtcp2_cid *cid)

    
     `ngtcp2_crypto_generate_stateless_reset_token` generates a
     stateless reset token using HKDF extraction using the given *cid*
     and *secret* as input.  The token will be written to the buffer
     pointed by *token*, and it must have a capacity of at least
     :macro:`NGTCP2_STATELESS_RESET_TOKENLEN` bytes.
    
    This function returns 0 if it succeeds, or -1.
