=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. These functions are deprecated.
|
||
|
|
Applications should instead use EVP_PKEY_CTX_set_dh_rfc5114() and
|
||
|
|
EVP_PKEY_CTX_set_dhx_rfc5114() as described in L<EVP_PKEY_CTX_ctrl(3)> or
|
||
|
|
by setting the B<OSSL_PKEY_PARAM_GROUP_NAME> as specified in
|
||
|
|
L<EVP_PKEY-DH(7)/DH parameters>) to one of "dh_1024_160", "dh_2048_224" or
|
||
|
|
"dh_2048_256".
|
||
|
|
|
||
|
|
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.

|

Defined above.
