C++ (Cpp) shkey_cert Examples

Example #1

static void generate_bond_signature(tx_bond_t *bond)
{
  shkey_t *sig_key;
  uint64_t crc;

  crc = (uint64_t)shcrc(bond->bond_sink, strlen(bond->bond_sink));
  sig_key = shkey_cert(&bond->bond_key, crc, bond->bond_expire);
  memcpy(&bond->bond_sig, sig_key, sizeof(shkey_t));
  shkey_free(&sig_key);
}

Example #2

void generate_asset_signature(tx_asset_t *asset, shpeer_t *peer)
{
  shkey_t *sig_key;
  uint64_t crc;

  if (asset->ass.ass_expire == SHTIME_UNDEFINED)
    asset->ass.ass_expire = shtime_adj(shtime(), SHARE_DEFAULT_EXPIRE_TIME); 

  crc = shcrc((unsigned char *)asset->ass_data, asset->ass_size);
  sig_key = shkey_cert(shpeer_kpriv(peer), crc, asset->ass.ass_expire);
  memcpy(&asset->ass.ass_sig, sig_key, sizeof(shkey_t));
  shkey_free(&sig_key);

}

Example #3

File: shmem_key.c Project: neonatura/share

int shkey_verify(shkey_t *sig, uint64_t crc, shkey_t *key, shtime_t stamp)
{
  shkey_t *sha_key;
  char *ptr;
  int valid;

  sha_key = shkey_cert(key, crc, stamp);

  valid = shkey_cmp(sha_key, sig);
  shkey_free(&sha_key);
  if (!valid)
    return (SHERR_INVAL);

  return (0);
}

Example #4

/** Associated a particular context with releasing a ward. */
void txward_context_sign(tx_ward_t *ward, tx_context_t *ctx)
{
  shkey_t *sig_key;

  if (!ward || !ctx)
    return;

  if (!shkey_cmp(&ward->ward_ref, &ctx->ctx_ref))
    return (SHERR_INVAL);

  if (ward->ward_tx.tx_stamp == SHTIME_UNDEFINED)
    ward->ward_tx.tx_stamp = shtime();

  sig_key = shkey_cert(&ctx->ctx_sig,
      shkey_crc(&ctx->ctx_ref), ward->ward_tx.tx_stamp);
  memcpy(&ward->ward_sig, sig_key, sizeof(ward->ward_sig));
  shkey_free(&sig_key);
