NAME

6       SSL - OpenSSL SSL/TLS library
7

SYNOPSIS

DESCRIPTION

10       The OpenSSL ssl library implements the Secure Sockets Layer (SSL v2/v3)
11       and Transport Layer Security (TLS v1) protocols. It provides a rich API
12       which is documented here.
13
14       At first the library must be initialized; see SSL_library_init(3).
15
16       Then 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
20       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
25       Then the TLS/SSL handshake is performed using SSL_accept(3) or
26       SSL_connect(3) respectively.  SSL_read(3) and SSL_write(3) are used to
27       read and write data on the TLS/SSL connection.  SSL_shutdown(3) can be
28       used to shut down the TLS/SSL connection.

DATA STRUCTURES

31       Currently the OpenSSL ssl library functions deals with the following
32       data structures:
33
34       SSL_METHOD (SSL Method)
35           That's a dispatch structure describing the internal ssl library
36           methods/functions which implement the various protocol versions
37           (SSLv1, SSLv2 and TLSv1). It's needed to create an SSL_CTX.
38
39       SSL_CIPHER (SSL Cipher)
40           This structure holds the algorithm information for a particular
41           cipher which are a core part of the SSL/TLS protocol. The available
42           ciphers are configured on a SSL_CTX basis and the actually used
43           ones are then part of the SSL_SESSION.
44
45       SSL_CTX (SSL Context)
46           That's the global context structure which is created by a server or
47           client once per program life-time and which holds mainly default
48           values for the SSL structures which are later created for the
49           connections.
50
51       SSL_SESSION (SSL Session)
52           This is a structure containing the current TLS/SSL session details
53           for a connection: SSL_CIPHERs, client and server certificates,
54           keys, etc.
55
56       SSL (SSL Connection)
57           That's the main SSL/TLS structure which is created by a server or
58           client per established connection. This actually is the core
59           structure in the SSL API.  Under run-time the application usually
60           deals with this structure which has links to mostly all other
61           structures.
62

HEADER FILES

64       Currently the OpenSSL ssl library provides the following C header files
65       containing the prototypes for the data structures and and functions:
66
67       ssl.h
68           That's the common header file for the SSL/TLS API.  Include it into
69           your program to make the API of the ssl library available. It
70           internally includes both more private SSL headers and headers from
71           the crypto library.  Whenever you need hard-core details on the
72           internals of the SSL API, look inside this header file.
73
74       ssl2.h
75           That's the sub header file dealing with the SSLv2 protocol only.
76           Usually you don't have to include it explicitly because it's
77           already included by ssl.h.
78
79       ssl3.h
80           That's the sub header file dealing with the SSLv3 protocol only.
81           Usually you don't have to include it explicitly because it's
82           already included by ssl.h.
83
84       ssl23.h
85           That's the sub header file dealing with the combined use of the
86           SSLv2 and SSLv3 protocols.  Usually you don't have to include it
87           explicitly because it's already included by ssl.h.
88
89       tls1.h
90           That's the sub header file dealing with the TLSv1 protocol only.
91           Usually you don't have to include it explicitly because it's
92           already included by ssl.h.
93

API FUNCTIONS

95       Currently the OpenSSL ssl library exports 214 API functions.  They are
96       documented in the following:

162           Constructor for the SSLv2 SSL_METHOD structure for servers.
163
164   DEALING WITH CIPHERS
165       Here we document the various API functions which deal with the SSL/TLS
166       ciphers defined in SSL_CIPHER structures.
167
168       char *SSL_CIPHER_description(SSL_CIPHER *cipher, char *buf, int len);
169           Write a string to buf (with a maximum size of len) containing a
170           human readable description of cipher. Returns buf.
171
172       int SSL_CIPHER_get_bits(SSL_CIPHER *cipher, int *alg_bits);
173           Determine the number of bits in cipher. Because of export crippled
174           ciphers there are two bits: The bits the algorithm supports in
175           general (stored to alg_bits) and the bits which are actually used
176           (the return value).
177
178       const char *SSL_CIPHER_get_name(SSL_CIPHER *cipher);
179           Return the internal name of cipher as a string. These are the
180           various strings defined by the SSL2_TXT_xxx, SSL3_TXT_xxx and
181           TLS1_TXT_xxx definitions in the header files.
182
183       char *SSL_CIPHER_get_version(SSL_CIPHER *cipher);
184           Returns a string like ""TLSv1/SSLv3"" or ""SSLv2"" which indicates
185           the SSL/TLS protocol version to which cipher belongs (i.e. where it
186           was defined in the specification the first time).
187
188   DEALING WITH PROTOCOL CONTEXTS
189       Here we document the various API functions which deal with the SSL/TLS
190       protocol context defined in the SSL_CTX structure.

278

280           is required. The "export" flag will be set if the reason for
281           needing a temp key is that an export ciphersuite is in use, in
