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
