+=head1 NAME
+
+SSL_get_current_cipher, SSL_get_cipher_name, SSL_get_cipher,
+SSL_get_cipher_bits, SSL_get_cipher_version,
+SSL_get_pending_cipher - get SSL_CIPHER of a connection
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ SSL_CIPHER *SSL_get_current_cipher(const SSL *ssl);
+ SSL_CIPHER *SSL_get_pending_cipher(const SSL *ssl);
+
+ const char *SSL_get_cipher_name(const SSL *s);
+ const char *SSL_get_cipher(const SSL *s);
+ int SSL_get_cipher_bits(const SSL *s, int *np);
+ const char *SSL_get_cipher_version(const SSL *s);
+
+=head1 DESCRIPTION
+
+SSL_get_current_cipher() returns a pointer to an SSL_CIPHER object containing
+the description of the actually used cipher of a connection established with
+the B<ssl> object.
+See L<SSL_CIPHER_get_name(3)> for more details.
+
+SSL_get_cipher_name() obtains the
+name of the currently used cipher.
+SSL_get_cipher() is identical to SSL_get_cipher_name().
+SSL_get_cipher_bits() is a
+macro to obtain the number of secret/algorithm bits used and
+SSL_get_cipher_version() returns the protocol name.
+
+SSL_get_pending_cipher() returns a pointer to an SSL_CIPHER object containing
+the description of the cipher (if any) that has been negotiated for future use
+on the connection established with the B<ssl> object, but is not yet in use.
+This may be the case during handshake processing, when control flow can be
+returned to the application via any of several callback methods. The internal
+sequencing of handshake processing and callback invocation is not guaranteed
+to be stable from release to release, and at present only the callback set
+by SSL_CTX_set_alpn_select_cb() is guaranteed to have a non-NULL return value.
+Other callbacks may be added to this list over time.
+
+=head1 RETURN VALUES
+
+SSL_get_current_cipher() returns the cipher actually used, or NULL if
+no session has been established.
+
+SSL_get_pending_cipher() returns the cipher to be used at the next change
+of cipher suite, or NULL if no such cipher is known.
+
+=head1 NOTES
+
+SSL_get_cipher, SSL_get_cipher_bits, SSL_get_cipher_version, and
+SSL_get_cipher_name are implemented as macros.
