gnutls_pkcs12_bag_enc_info(3)

NAME
gnutls_pkcs12_bag_enc_info - API function

SYNOPSIS
#include <gnutls/pkcs12.h>

int gnutls_pkcs12_bag_enc_info(gnutls_pkcs12_bag_t bag, unsigned int * schema, unsigned int * cipher, void * salt, unsigned int * salt_size, unsigned int * iter_count, char ** oid);

ARGUMENTS

gnutls_pkcs12_bag_t bag
    The bag

unsigned int * schema
    indicate the schema as one of gnutls_pkcs_encrypt_flags_t

unsigned int * cipher
    the cipher used as gnutls_cipher_algorithm_t

void * salt
    PBKDF2 salt (if non-NULL then salt_size initially holds its size)

unsigned int * salt_size
    PBKDF2 salt size

unsigned int * iter_count
    PBKDF2 iteration count

char ** oid
    if non-NULL it will contain an allocated null-terminated variable with the OID

DESCRIPTION
This function will provide information on the encryption algorithms used in an encrypted bag. If the structure algorithms are unknown the code GNUTLS_E_UNKNOWN_CIPHER_TYPE will be returned, and only oid , will be set. That is, oid will be set on encrypted bags whether supported or not. It must be deinitialized using gnutls_free(). The other variables are only set on supported structures.

RETURNS
GNUTLS_E_INVALID_REQUEST if the provided bag isn't encrypted, GNUTLS_E_UNKNOWN_CIPHER_TYPE if the structure's encryption isn't supported, or another negative error code in case of a failure. Zero on success.
