After the \fB\s-1SSL\s0\fR object has been created using +\&\fBSSL_new\fR\|(3), \fBSSL_set_fd\fR\|(3) or +\&\fBSSL_set_bio\fR\|(3) can be used to associate the network +connection with the object. +.PP +When the \s-1TLS/SSL\s0 handshake is performed using +\&\fBSSL_accept\fR\|(3) or \fBSSL_connect\fR\|(3) +respectively. +\&\fBSSL_read_ex\fR\|(3), \fBSSL_read\fR\|(3), \fBSSL_write_ex\fR\|(3) and \fBSSL_write\fR\|(3) are +used to read and write data on the \s-1TLS/SSL\s0 connection. +\&\fBSSL_shutdown\fR\|(3) can be used to shut down the +\&\s-1TLS/SSL\s0 connection. +.SH "DATA STRUCTURES" +.IX Header "DATA STRUCTURES" +Here are some of the main data structures in the library. +.IP "\fB\s-1SSL_METHOD\s0\fR (\s-1SSL\s0 Method)" 4 +.IX Item "SSL_METHOD (SSL Method)" +This is a dispatch structure describing the internal \fBssl\fR library +methods/functions which implement the various protocol versions (SSLv3 +TLSv1, ...). It's needed to create an \fB\s-1SSL_CTX\s0\fR. +.IP "\fB\s-1SSL_CIPHER\s0\fR (\s-1SSL\s0 Cipher)" 4 +.IX Item "SSL_CIPHER (SSL Cipher)" +This structure holds the algorithm information for a particular cipher which +are a core part of the \s-1SSL/TLS\s0 protocol. The available ciphers are configured +on a \fB\s-1SSL_CTX\s0\fR basis and the actual ones used are then part of the +\&\fB\s-1SSL_SESSION\s0\fR. +.IP "\fB\s-1SSL_CTX\s0\fR (\s-1SSL\s0 Context)" 4 +.IX Item "SSL_CTX (SSL Context)" +This is the global context structure which is created by a server or client +once per program life-time and which holds mainly default values for the +\&\fB\s-1SSL\s0\fR structures which are later created for the connections. +.IP "\fB\s-1SSL_SESSION\s0\fR (\s-1SSL\s0 Session)" 4 +.IX Item "SSL_SESSION (SSL Session)" +This is a structure containing the current \s-1TLS/SSL\s0 session details for a +connection: \fB\s-1SSL_CIPHER\s0\fRs, client and server certificates, keys, etc. +.IP "\fB\s-1SSL\s0\fR (\s-1SSL\s0 Connection)" 4 +.IX Item "SSL (SSL Connection)" +This is the main \s-1SSL/TLS\s0 structure which is created by a server or client per +established connection. This actually is the core structure in the \s-1SSL API.\s0 +At run-time the application usually deals with this structure which has +links to mostly all other structures. +.SH "HEADER FILES" +.IX Header "HEADER FILES" +Currently the OpenSSL \fBssl\fR library provides the following C header files +containing the prototypes for the data structures and functions: +.IP "\fI<openssl/ssl.h>\fR" 4 +.IX Item "<openssl/ssl.h>" +This is the common header file for the \s-1SSL/TLS API.\s0 Include it into your +program to make the \s-1API\s0 of the \fBssl\fR library available. It internally +includes both more private \s-1SSL\s0 headers and headers from the \fBcrypto\fR library. +Whenever you need hard-core details on the internals of the \s-1SSL API,\s0 look +inside this header file. +This file also includes the others listed below. +.IP "\fI<openssl/ssl2.h>\fR" 4 +.IX Item "<openssl/ssl2.h>" +Unused. Present for backwards compatibility only. +.IP "\fI<openssl/ssl3.h>\fR" 4 +.IX Item "<openssl/ssl3.h>" +This is the sub header file dealing with the SSLv3 protocol only. +.IP "\fI<openssl/tls1.h>\fR" 4 +.IX Item "<openssl/tls1.h>" +This is the sub header file dealing with the TLSv1 protocol only. +.SH "COPYRIGHT" +.IX Header "COPYRIGHT" +Copyright 2000\-2018 The OpenSSL Project Authors.
