gnutls_pkcs8_info(3)              gnutls             gnutls_pkcs8_info(3)

NAME         top

       gnutls_pkcs8_info - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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.
