5d2i_DHparams, i2d_DHparams - PKCS#3 DH parameter functions
6
7=head1 SYNOPSIS
8
9 #include <openssl/dh.h>
10
11 DH *d2i_DHparams(DH **a, unsigned char **pp, long length);
12 int i2d_DHparams(DH *a, unsigned char **pp);
13
14=head1 DESCRIPTION
15
16These functions decode and encode PKCS#3 DH parameters using the
17DHparameter structure described in PKCS#3.
18
19Otherwise these behave in a similar way to d2i_X509() and i2d_X509()
20described in the L<d2i_X509(3)> manual page.
21
22=head1 RETURN VALUES
23
24d2i_DHparams() returns a valid B<DH> structure or NULL if an error occurred.
25
26i2d_DHparams() returns the length of encoded data on success or a value which
27is less than or equal to 0 on error.
