| 3 | =head1 NAME |
| 4 | |
| 5 | d2i_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, const unsigned char **pp, long length); |
| 12 | int i2d_DHparams(DH *a, unsigned char **pp); |
| 13 | |
| 14 | =head1 DESCRIPTION |
| 15 | |
| 16 | These functions decode and encode PKCS#3 DH parameters using the |
| 17 | DHparameter structure described in PKCS#3. |
| 18 | |
| 19 | Otherwise these behave in a similar way to d2i_X509() and i2d_X509() |
| 20 | described in the L<d2i_X509(3)> manual page. |
| 21 | |
| 22 | =head1 RETURN VALUES |
| 23 | |
| 24 | d2i_DHparams() returns a valid B<DH> structure or NULL if an error occurred. |
| 25 | |
| 26 | i2d_DHparams() returns the length of encoded data on success or a value which |
| 27 | is less than or equal to 0 on error. |
