C++ (Cpp) _krb5_HMAC_MD5_checksum Examples

Example #1

static krb5_error_code
HMAC_MD5_any_checksum(krb5_context context,
		      const krb5_keyblock *key,
		      const void *data,
		      size_t len,
		      unsigned usage,
		      Checksum *result)
{
    struct key_data local_key;
    krb5_error_code ret;

    memset(&local_key, 0, sizeof(local_key));

    ret = krb5_copy_keyblock(context, key, &local_key.key);
    if (ret)
	return ret;

    ret = krb5_data_alloc (&result->checksum, 16);
    if (ret) {
	krb5_free_keyblock(context, local_key.key);
	return ret;
    }

    result->cksumtype = CKSUMTYPE_HMAC_MD5;

    if (ret)
	krb5_data_free(&result->checksum);
