NAME
gnutls_pkcs8_info - API function
SYNOPSIS
#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 8 data
gnutls_x509_crt_fmt_t format
the format of the PKCS 8 data
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 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.
SINCE
3.4.0
