SSL_get_current_cipher

NAME

SSL_get_current_cipher, SSL_get_cipher_name, SSL_get_cipher, SSL_get_cipher_bits, SSL_get_cipher_version - get SSL_CIPHER of a connection

SYNOPSIS

 #include <openssl/ssl.h>

 SSL_CIPHER *SSL_get_current_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);

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 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.

RETURN VALUES

SSL_get_current_cipher() returns the cipher actually used, or NULL if no session has been established.

NOTES

These are implemented as macros.
