+=head1 NAME
+
+SSL_CTX_set_cipher_list, SSL_set_cipher_list - choose list of available SSL_CIPHERs
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_CTX_set_cipher_list(SSL_CTX *ctx, const char *str);
+ int SSL_set_cipher_list(SSL *ssl, const char *str);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_cipher_list() sets the list of available ciphers for B<ctx>
+using the control string B<str>. The format of the string is described
+in L<ciphers(1)>. The list of ciphers is inherited by all
+B<ssl> objects created from B<ctx>.
+
+SSL_set_cipher_list() sets the list of ciphers only for B<ssl>.
+
+=head1 NOTES
+
+The control string B<str> should be universally usable and not depend
+on details of the library configuration (ciphers compiled in). Thus no
+syntax checking takes place. Items that are not recognized, because the
+corresponding ciphers are not compiled in or because they are mistyped,
+are simply ignored. Failure is only flagged if no ciphers could be collected
+at all.
+
+It should be noted, that inclusion of a cipher to be used into the list is
+a necessary condition. On the client side, the inclusion into the list is
+also sufficient unless the security level excludes it. On the server side,
+additional restrictions apply. All ciphers have additional requirements.
+ADH ciphers don't need a certificate, but DH-parameters must have been set.
+All other ciphers need a corresponding certificate and key.
+
+A RSA cipher can only be chosen, when a RSA certificate is available.
+RSA ciphers using DHE need a certificate and key and additional DH-parameters
+(see L<SSL_CTX_set_tmp_dh_callback(3)>).
+
+A DSA cipher can only be chosen, when a DSA certificate is available.
+DSA ciphers always use DH key exchange and therefore need DH-parameters
+(see L<SSL_CTX_set_tmp_dh_callback(3)>).
+
+When these conditions are not met for any cipher in the list (e.g. a
+client only supports export RSA ciphers with an asymmetric key length
+of 512 bits and the server is not configured to use temporary RSA
+keys), the "no shared cipher" (SSL_R_NO_SHARED_CIPHER) error is generated
+and the handshake will fail.
+
+=head1 RETURN VALUES
+
+SSL_CTX_set_cipher_list() and SSL_set_cipher_list() return 1 if any cipher
+could be selected and 0 on complete failure.
