1=pod 2 3=head1 NAME 4 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. 28 29=head1 SEE ALSO 30 31L<d2i_X509(3)> 32 33=head1 COPYRIGHT 34 35Copyright 2000-2018 The OpenSSL Project Authors.
