# gnutls\_pkcs11\_obj\_get\_pk\_algorithm(3)

API function

## NAME

gnutls\_pkcs11\_obj\_get\_pk\_algorithm - API function

## SYNOPSIS

**#include \<gnutls/pkcs11.h\>**

**int gnutls\_pkcs11\_obj\_get\_pk\_algorithm(gnutls\_pkcs11\_obj\_t** *obj***, unsigned int \*** *bits***);**

## ARGUMENTS

- gnutls\_pkcs11\_obj\_t obj

  The pkcs11 object

- unsigned int \* bits

  Will hold the rsa/dsa bit count or the ecc curve This function given a pkcs11 object with privkey\_type initialized, will return the algorithm type on success , and will store the number of bits if the algo type is **GNUTLS\_PK\_RSA** or **GNUTLS\_PK\_DSA**, or the curve if the algo type is **GNUTLS\_PK\_ECDSA**.

## DESCRIPTION

The return value needs to be checked to determine if bits represents the ecc curve or the number of bits.

## RETURNS

The private key algorithm associated with the object on success or a an error code otherwise.

## SINCE

3\.8.13
