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
ssl object. See
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
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.
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.
SSL_get_cipher, SSL_get_cipher_bits, SSL_get_cipher_version, and
SSL_get_cipher_name are implemented as macros.
