NAME
d2i_DHparams, i2d_DHparams – PKCS#3 DH parameter functions
SYNOPSIS
Crypto Library (libcrypto, -lcrypto)
#include <openssl/dh.h>
DH *
d2i_DHparams(DH **a, unsigned char **pp, long length);
int
i2d_DHparams(DH *a, unsigned char **pp);
DESCRIPTION
These functions decode and encode PKCS#3 DH parameters using the DHparameter structure described in PKCS#3. They otherwise behave in a way similar to d2i_X509(3) and i2d_X509(3).
RETURN VALUES
d2i_DHparams() returns a DH object or NULL if an error occurs.
i2d_DHparams() returns the number of bytes successfully encoded or a value <= 0 if an error occurs.
SEE ALSO
d2i_X509(3), DH_new(3)
HISTORY
d2i_DHparams() and i2d_DHparams() first appeared in SSLeay 0.5.1 and have been available since OpenBSD 2.4.
