SYNOPSIS
#include
<openssl/ssl.h>
const SSL_CIPHER *
SSL_get_current_cipher(const
SSL *ssl);
const char *
SSL_get_cipher(const
SSL *ssl);
const char *
SSL_get_cipher_name(const
SSL *ssl);
int
SSL_get_cipher_bits(const
SSL *ssl, int
*np);
char *
SSL_get_cipher_version(const
SSL *ssl);
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 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()
obtains the number of secret/algorithm bits used and
SSL_get_cipher_version()
returns the protocol name.
SSL_get_cipher(),
SSL_get_cipher_name(),
SSL_get_cipher_bits(), and
SSL_get_cipher_version() are implemented as
macros.
RETURN VALUES
SSL_get_current_cipher() returns the
cipher actually used, or NULL if no session has been
established.
