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.
