=head1 DESCRIPTION

DH_get_1024_160(), DH_get_2048_224(), and DH_get_2048_256() each return
a DH object for the IETF RFC 5114 value.

BN_get0_nist_prime_192(), BN_get0_nist_prime_224(), BN_get0_nist_prime_256(),
BN_get0_nist_prime_384(), and BN_get0_nist_prime_521() functions return
a BIGNUM for the specific NIST prime curve (e.g., P-256).

BN_get_rfc2409_prime_768(), BN_get_rfc2409_prime_1024(),
BN_get_rfc3526_prime_1536(), BN_get_rfc3526_prime_2048(),
BN_get_rfc3526_prime_3072(), BN_get_rfc3526_prime_4096(),
BN_get_rfc3526_prime_6144(), and BN_get_rfc3526_prime_8192() functions
return a BIGNUM for the specified size from IETF RFC 2409.  If B<bn>
is not NULL, the BIGNUM will be set into that location as well.
