gnutls_pkcs8_info3
Api function
Usage
#include <gnutls/x509.h>
int gnutls_pkcs8_info(const gnutls_datum_t * data, gnutls_x509_crt_fmt_t format, unsigned int * schema, unsigned int * cipher, void * salt, unsigned int * salt_size, unsigned int * iter_count, char ** oid);
Arguments
const gnutls_datum_t * data
|
Holds the PKCS |
|---|---|
gnutls_x509_crt_fmt_t format
|
the format of the PKCS |
unsigned int * schema
|
indicate the schema as one of |
unsigned int * cipher
|
the cipher used as |
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 |
Overview
This function will provide information on the algorithms used in a particular PKCS 8 structure. 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 PKCS 8 structures 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 structure isn't an encrypted key, 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.
