9 See the individual manual pages for details.
10
12 The OpenSSL ssl library implements the Secure Sockets Layer (SSL v2/v3)
13 and Transport Layer Security (TLS v1) protocols. It provides a rich API
14 which is documented here.
15 An SSL_CTX object is created as a framework to establish TLS/SSL
17 enabled connections (see SSL_CTX_new(3)). Various options regarding
18 certificates, algorithms etc. can be set in this object.
19 When a network connection has been created, it can be assigned to an
21 SSL object. After the SSL object has been created using SSL_new(3),
22 SSL_set_fd(3) or SSL_set_bio(3) can be used to associate the network
23 connection with the object.
24 When the TLS/SSL handshake is performed using SSL_accept(3) or
26 SSL_connect(3) respectively. SSL_read_ex(3), SSL_read(3),
27 SSL_write_ex(3) and SSL_write(3) are used to read and write data on the
28 TLS/SSL connection. SSL_shutdown(3) can be used to shut down the
29 TLS/SSL connection.
30
32 Currently the OpenSSL ssl library functions deals with the following
33 data structures:
34 SSL_METHOD (SSL Method)
36 This is a dispatch structure describing the internal ssl library
37 methods/functions which implement the various protocol versions
38 (SSLv3 TLSv1, ...). It's needed to create an SSL_CTX.
39 SSL_CIPHER (SSL Cipher)
41 This structure holds the algorithm information for a particular
42 cipher which are a core part of the SSL/TLS protocol. The available
43 ciphers are configured on a SSL_CTX basis and the actual ones used
44 are then part of the SSL_SESSION.
45 SSL_CTX (SSL Context)
47 This is the global context structure which is created by a server
48 or client once per program life-time and which holds mainly default
49 values for the SSL structures which are later created for the
50 connections.
51 SSL_SESSION (SSL Session)
53 This is a structure containing the current TLS/SSL session details
54 for a connection: SSL_CIPHERs, client and server certificates,
55 keys, etc.
56 SSL (SSL Connection)
58 This is the main SSL/TLS structure which is created by a server or
59 client per established connection. This actually is the core
60 structure in the SSL API. At run-time the application usually
61 deals with this structure which has links to mostly all other
62 structures.
63
65 Currently the OpenSSL ssl library provides the following C header files
66 containing the prototypes for the data structures and functions:
67 ssl.h
69 This is the common header file for the SSL/TLS API. Include it
70 into your program to make the API of the ssl library available. It
71 internally includes both more private SSL headers and headers from
72 the crypto library. Whenever you need hard-core details on the
73 internals of the SSL API, look inside this header file.
74 ssl2.h
76 Unused. Present for backwards compatibility only.
77 ssl3.h
79 This is the sub header file dealing with the SSLv3 protocol only.
80 Usually you don't have to include it explicitly because it's
81 already included by ssl.h.
82 tls1.h
84 This is the sub header file dealing with the TLSv1 protocol only.
85 Usually you don't have to include it explicitly because it's
86 already included by ssl.h.
87
89 Currently the OpenSSL ssl library exports 214 API functions. They are
90 documented in the following:
91 Dealing with Protocol Methods
93 Here we document the various API functions which deal with the SSL/TLS
94 protocol methods defined in SSL_METHOD structures.
95 const SSL_METHOD *TLS_method(void);
97 Constructor for the version-flexible SSL_METHOD structure for
98 clients, servers or both. See SSL_CTX_new(3) for details.
99 const SSL_METHOD *TLS_client_method(void);
101 Constructor for the version-flexible SSL_METHOD structure for
102 clients. Must be used to support the TLSv1.3 protocol.
103 const SSL_METHOD *TLS_server_method(void);
105 Constructor for the version-flexible SSL_METHOD structure for
106 servers. Must be used to support the TLSv1.3 protocol.
107 const SSL_METHOD *TLSv1_2_method(void);
109 Constructor for the TLSv1.2 SSL_METHOD structure for clients,
110 servers or both.
111 const SSL_METHOD *TLSv1_2_client_method(void);
113 Constructor for the TLSv1.2 SSL_METHOD structure for clients.
114 const SSL_METHOD *TLSv1_2_server_method(void);
116 Constructor for the TLSv1.2 SSL_METHOD structure for servers.
117 const SSL_METHOD *TLSv1_1_method(void);
119 Constructor for the TLSv1.1 SSL_METHOD structure for clients,
120 servers or both.
121 const SSL_METHOD *TLSv1_1_client_method(void);
123 Constructor for the TLSv1.1 SSL_METHOD structure for clients.
124 const SSL_METHOD *TLSv1_1_server_method(void);
126 Constructor for the TLSv1.1 SSL_METHOD structure for servers.
127 const SSL_METHOD *TLSv1_method(void);
129 Constructor for the TLSv1 SSL_METHOD structure for clients, servers
130 or both.
131 const SSL_METHOD *TLSv1_client_method(void);
133 Constructor for the TLSv1 SSL_METHOD structure for clients.
134 const SSL_METHOD *TLSv1_server_method(void);
136 Constructor for the TLSv1 SSL_METHOD structure for servers.
137 const SSL_METHOD *SSLv3_method(void);
139 Constructor for the SSLv3 SSL_METHOD structure for clients, servers
140 or both.
141 const SSL_METHOD *SSLv3_client_method(void);
143 Constructor for the SSLv3 SSL_METHOD structure for clients.
144 const SSL_METHOD *SSLv3_server_method(void);
146 Constructor for the SSLv3 SSL_METHOD structure for servers.
147 Dealing with Ciphers
149 Here we document the various API functions which deal with the SSL/TLS
150 ciphers defined in SSL_CIPHER structures.
151 char *SSL_CIPHER_description(SSL_CIPHER *cipher, char *buf, int len);
153 Write a string to buf (with a maximum size of len) containing a
154 human readable description of cipher. Returns buf.
155 int SSL_CIPHER_get_bits(SSL_CIPHER *cipher, int *alg_bits);
157 Determine the number of bits in cipher. Because of export crippled
158 ciphers there are two bits: The bits the algorithm supports in
159 general (stored to alg_bits) and the bits which are actually used
160 (the return value).
161 const char *SSL_CIPHER_get_name(SSL_CIPHER *cipher);
163 Return the internal name of cipher as a string. These are the
164 various strings defined by the SSL3_TXT_xxx and TLS1_TXT_xxx
165 definitions in the header files.
166 const char *SSL_CIPHER_get_version(SSL_CIPHER *cipher);
168 Returns a string like ""SSLv3"" or ""TLSv1.2"" which indicates the
169 SSL/TLS protocol version to which cipher belongs (i.e. where it was
170 defined in the specification the first time).
171 Dealing with Protocol Contexts
173 Here we document the various API functions which deal with the SSL/TLS
174 protocol context defined in the SSL_CTX structure.

321 long SSL_SESSION_set_timeout(SSL_SESSION *s, long t);
322 Dealing with Connections
324 Here we document the various API functions which deal with the SSL/TLS
325 connection defined in the SSL structure.
326 int SSL_accept(SSL *ssl);
328 int SSL_add_dir_cert_subjects_to_stack(STACK *stack, const char *dir);
329 int SSL_add_file_cert_subjects_to_stack(STACK *stack, const char
330 *file);
331 int SSL_add_client_CA(SSL *ssl, X509 *x);
332 char *SSL_alert_desc_string(int value);
333 char *SSL_alert_desc_string_long(int value);
334 char *SSL_alert_type_string(int value);
335 char *SSL_alert_type_string_long(int value);
336 int SSL_check_private_key(const SSL *ssl);
337 void SSL_clear(SSL *ssl);
338 long SSL_clear_num_renegotiations(SSL *ssl);
339 int SSL_connect(SSL *ssl);
340 int SSL_copy_session_id(SSL *t, const SSL *f);
341 Sets the session details for t to be the same as in f. Returns 1 on
342 success or 0 on failure.
343 long SSL_ctrl(SSL *ssl, int cmd, long larg, char *parg);
345 int SSL_do_handshake(SSL *ssl);
346 SSL *SSL_dup(SSL *ssl);
347 SSL_dup() allows applications to configure an SSL handle for use in
348 multiple SSL connections, and then duplicate it prior to initiating
349 each connection with the duplicated handle. Use of SSL_dup()
350 avoids the need to repeat the configuration of the handles for each
351 connection.
352 For SSL_dup() to work, the connection MUST be in its initial state
354 and MUST NOT have not yet have started the SSL handshake. For
355 connections that are not in their initial state SSL_dup() just
356 increments an internal reference count and returns the same handle.
357 It may be possible to use SSL_clear(3) to recycle an SSL handle
358 that is not in its initial state for re-use, but this is best
359 avoided. Instead, save and restore the session, if desired, and
360 construct a fresh handle for each connection.
