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

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.
