=head1 DESCRIPTION
L<SSL_clear(3)|SSL_clear(3)> is called for this SSL object.
SSL_CTX_use_certificate() loads the certificate B<x> into B<ctx>,
-SSL_use_certificate() loads B<x> into B<ssl>.
+SSL_use_certificate() loads B<x> into B<ssl>. The rest of the
+certificates needed to form the complete certificate chain can be
+specified using the
+L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>
+function.
SSL_CTX_use_certificate_ASN1() loads the ASN1 encoded certificate from
the memory location B<d> (with length B<len>) into B<ctx>,
into B<ctx>. The formatting B<type> of the certificate must be specified
from the known types SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.
SSL_use_certificate_file() loads the certificate from B<file> into B<ssl>.
+See the NOTES section on why SSL_CTX_use_certificate_chain_file()
+should be preferred.
SSL_CTX_use_certificate_chain_file() loads a certificate chain from
B<file> into B<ctx>. The certificates must be in PEM format and must
-be sorted starting with the certificate to the highest level (root CA).
+be sorted starting with the subject's certificate (actual client or server
+certificate), followed by intermediate CA certificates if applicable, and
+ending at the highest level (root) CA.
There is no corresponding function working on a single SSL object.
SSL_CTX_use_PrivateKey() adds B<pkey> as private key to B<ctx>.
SSL_CTX_use_RSAPrivateKey() adds the private key B<rsa> of type RSA
to B<ctx>. SSL_use_PrivateKey() adds B<pkey> as private key to B<ssl>;
SSL_use_RSAPrivateKey() adds B<rsa> as private key of type RSA to B<ssl>.
+If a certificate has already been set and the private does not belong
+to the certificate an error is returned. To change a certificate, private
+key pair the new certificate needs to be set with SSL_use_certificate()
+or SSL_CTX_use_certificate() before setting the private key with
+SSL_CTX_use_PrivateKey() or SSL_use_PrivateKey().
+
SSL_CTX_use_PrivateKey_ASN1() adds the private key of type B<pk>
stored at memory location B<d> (length B<len>) to B<ctx>.
to the store of chain certificates using
L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>.
There exists only one extra chain store, so that the same chain is appended
-to both types of certificates, RSA and DSA!
+to both types of certificates, RSA and DSA! If it is not intended to use
+both type of certificate at the same time, it is recommended to use the
+SSL_CTX_use_certificate_chain_file() instead of the
+SSL_CTX_use_certificate_file() function in order to allow the use of
+complete certificate chains even when no trusted CA storage is used or
+when the CA issuing the certificate shall not be added to the trusted
+CA storage.
If additional certificates are needed to complete the chain during the
TLS negotiation, CA certificates are additionally looked up in the
L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>,
L<SSL_CTX_set_default_passwd_cb(3)|SSL_CTX_set_default_passwd_cb(3)>,
L<SSL_CTX_set_cipher_list(3)|SSL_CTX_set_cipher_list(3)>,
+L<SSL_CTX_set_client_cert_cb(3)|SSL_CTX_set_client_cert_cb(3)>,
L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>
+=head1 HISTORY
+
+Support for DER encoded private keys (SSL_FILETYPE_ASN1) in
+SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() was added
+in 0.9.8 .
