=head1 DESCRIPTION
|
|
|
|
d2i_DSAPublicKey() and i2d_DSAPublicKey() decode and encode the DSA public key
|
|
components structure.
|
|
|
|
d2i_DSA_PUBKEY() and i2d_DSA_PUBKEY() decode and encode an DSA public key using
|
|
a SubjectPublicKeyInfo (certificate public key) structure.
|
|
|
|
d2i_DSAPrivateKey(), i2d_DSAPrivateKey() decode and encode the DSA private key
|
|
components.
|
|
|
|
d2i_DSAparams(), i2d_DSAparams() decode and encode the DSA parameters using
|
|
a B<Dss-Parms> structure as defined in RFC2459.
|
|
|
|
d2i_DSA_SIG(), i2d_DSA_SIG() decode and encode a DSA signature using a
|
|
B<Dss-Sig-Value> structure as defined in RFC2459.
|
|
|
|
The usage of all of these functions is similar to the d2i_X509() and
|
|
i2d_X509() described in the L<d2i_X509(3)|d2i_X509(3)> manual page.
|
|
|
|
=head1 NOTES
|
|
|
|
The B<DSA> structure passed to the private key encoding functions should have
|
|
all the private key components present.
|
|
|
|
The data encoded by the private key functions is unencrypted and therefore
|
|
offers no private key security.
|
|
|
|
The B<DSA_PUBKEY> functions should be used in preference to the B<DSAPublicKey>
|
|
functions when encoding public keys because they use a standard format.
|
|
|
|
The B<DSAPublicKey> functions use an non standard format the actual data encoded
|
|
depends on the value of the B<write_params> field of the B<a> key parameter.
|
|
If B<write_params> is zero then only the B<pub_key> field is encoded as an
|
|
B<INTEGER>. If B<write_params> is 1 then a B<SEQUENCE> consisting of the
|
|
B<p>, B<q>, B<g> and B<pub_key> respectively fields are encoded.
|
|
|
|
The B<DSAPrivateKey> functions also use a non standard structure consiting
|
|
consisting of a SEQUENCE containing the B<p>, B<q>, B<g> and B<pub_key> and
|
|
B<priv_key> fields respectively.
