It provides a rich \s-1API\s0 which is documented here. .PP At first the library must be initialized; see \&\fBSSL_library_init\fR\|(3). .PP Then an \fB\s-1SSL_CTX\s0\fR object is created as a framework to establish \&\s-1TLS/SSL\s0 enabled connections (see \fBSSL_CTX_new\fR\|(3)). Various options regarding certificates, algorithms etc. can be set in this object. .PP When a network connection has been created, it can be assigned to an \&\fB\s-1SSL\s0\fR object. 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 Then the \s-1TLS/SSL\s0 handshake is performed using \&\fBSSL_accept\fR\|(3) or \fBSSL_connect\fR\|(3) respectively. \&\fBSSL_read\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" Currently the OpenSSL \fBssl\fR library functions deals with the following data structures: .IP "\fB\s-1SSL_METHOD\s0\fR (\s-1SSL\s0 Method)" 4 .IX Item "SSL_METHOD (SSL Method)" That's a dispatch structure describing the internal \fBssl\fR library methods/functions which implement the various protocol versions (SSLv1, SSLv2 and 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 actually used ones 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)" That's 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)" That's 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 Under 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 and functions: .IP "\fBssl.h\fR" 4 .IX Item "ssl.h" That's 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. .IP "\fBssl2.h\fR" 4 .IX Item "ssl2.h" That's the sub header file dealing with the SSLv2 protocol only. \&\fIUsually you don't have to include it explicitly because it's already included by ssl.h\fR. .IP "\fBssl3.h\fR" 4 .IX Item "ssl3.h" That's the sub header file dealing with the SSLv3 protocol only. \&\fIUsually you don't have to include it explicitly because it's already included by ssl.h\fR. .IP "\fBssl23.h\fR" 4 .IX Item "ssl23.h" That's the sub header file dealing with the combined use of the SSLv2 and SSLv3 protocols. \&\fIUsually you don't have to include it explicitly because it's already included by ssl.h\fR. .IP "\fBtls1.h\fR" 4 .IX Item "tls1.h" That's the sub header file dealing with the TLSv1 protocol only. \&\fIUsually you don't have to include it explicitly because it's already included by ssl.h\fR. .SH "API FUNCTIONS" .IX Header "API FUNCTIONS" Currently the OpenSSL \fBssl\fR library exports 214 \s-1API\s0 functions. They are documented in the following: .SS "\s-1DEALING WITH PROTOCOL METHODS\s0" .IX Subsection "DEALING WITH PROTOCOL METHODS" Here we document the various \s-1API\s0 functions which deal with the \s-1SSL/TLS\s0 protocol methods defined in \fB\s-1SSL_METHOD\s0\fR structures. .IP "const \s-1SSL_METHOD\s0 *\fBSSLv23_method\fR(void);" 4 .IX Item "const SSL_METHOD *SSLv23_method(void);" Constructor for the \fIversion-flexible\fR \s-1SSL_METHOD\s0 structure for clients, servers or both.
