1=pod 2 3=head1 NAME 4 5SSL_get_current_cipher, SSL_get_cipher, SSL_get_cipher_name, 6SSL_get_cipher_bits, SSL_get_cipher_version - get SSL_CIPHER of a connection 7 8=head1 SYNOPSIS 9 10 #include <openssl/ssl.h> 11 12 SSL_CIPHER *SSL_get_current_cipher(const SSL *ssl); 13 #define SSL_get_cipher(s) \ 14 SSL_CIPHER_get_name(SSL_get_current_cipher(s)) 15 #define SSL_get_cipher_name(s) \ 16 SSL_CIPHER_get_name(SSL_get_current_cipher(s)) 17 #define SSL_get_cipher_bits(s,np) \ 18 SSL_CIPHER_get_bits(SSL_get_current_cipher(s),np) 19 #define SSL_get_cipher_version(s) \ 20 SSL_CIPHER_get_version(SSL_get_current_cipher(s)) 21 22=head1 DESCRIPTION 23 24SSL_get_current_cipher() returns a pointer to an SSL_CIPHER object containing 25the description of the actually used cipher of a connection established with 26the B<ssl> object. 27 28SSL_get_cipher() and SSL_get_cipher_name() are identical macros to obtain the 29name of the currently used cipher. SSL_get_cipher_bits() is a 30macro to obtain the number of secret/algorithm bits used and 31SSL_get_cipher_version() returns the protocol name. 32See L<SSL_CIPHER_get_name(3)|SSL_CIPHER_get_name(3)> for more details. 33 34=head1 RETURN VALUES 35 36SSL_get_current_cipher() returns the cipher actually used or NULL, when 37no session has been established. 38 39=head1 SEE ALSO 40 41L<ssl(3)|ssl(3)>, L<SSL_CIPHER_get_name(3)|SSL_CIPHER_get_name(3)> 42 43=cut 44
