NAME         top

       gnutls_privkey_export_rsa_raw - API function

SYNOPSIS         top

       #include <gnutls/abstract.h>

       int gnutls_privkey_export_rsa_raw(gnutls_privkey_t key,
       gnutls_datum_t * m, gnutls_datum_t * e, gnutls_datum_t * d,
       gnutls_datum_t * p, gnutls_datum_t * q, gnutls_datum_t * u,
       gnutls_datum_t * e1, gnutls_datum_t * e2);

ARGUMENTS         top

       gnutls_privkey_t key
                   Holds the certificate

       gnutls_datum_t * m
                   will hold the modulus

       gnutls_datum_t * e
                   will hold the public exponent

       gnutls_datum_t * d
                   will hold the private exponent

       gnutls_datum_t * p
                   will hold the first prime (p)

       gnutls_datum_t * q
                   will hold the second prime (q)

       gnutls_datum_t * u
                   will hold the coefficient

       gnutls_datum_t * e1
                   will hold e1 = d mod (p-1)

       gnutls_datum_t * e2
                   will hold e2 = d mod (q-1)

DESCRIPTION         top

       This function will export the RSA private key's parameters found
       in the given structure. The new parameters will be allocated using
       gnutls_malloc() and will be stored in the appropriate datum. For
       EdDSA keys, the  y value should be NULL.

RETURNS         top

       GNUTLS_E_SUCCESS on success, otherwise a negative error code.

SINCE         top

       3.3.0
