# [NAME](#NAME)

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

# [SYNOPSIS](#SYNOPSIS)

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

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

# [ARGUMENTS](#ARGUMENTS)

[gnutls\_pkcs11\_obj\_t obj](#gnutls_pkcs11_obj_t)

The pkcs11 object

[unsigned int * bits](#unsigned)

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](#DESCRIPTION)

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

# [RETURNS](#RETURNS)

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