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    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.
