a9c85cea | 5 | ssl - OpenSSL SSL/TLS library |
3604a4d3 | 6 | |

9 | See the individual manual pages for details. | |
10 | ||
11b62699 | 11 | =head1 DESCRIPTION |
3604a4d3 UM |
12 | |
13 | The OpenSSL B<ssl> library implements the Secure Sockets Layer (SSL v2/v3) and | |
14 | Transport Layer Security (TLS v1) protocols. It provides a rich API which is | |
15 | documented here. | |
16 | ||
cbade361 | 17 | An B<SSL_CTX> object is created as a framework to establish |
9b86974e | 18 | TLS/SSL enabled connections (see L<SSL_CTX_new(3)>). |
9bd3bd22 UM |
19 | Various options regarding certificates, algorithms etc. can be set |
20 | in this object. | |
3604a4d3 | 21 | |
9bd3bd22 UM |
22 | When a network connection has been created, it can be assigned to an |
23 | B<SSL> object. After the B<SSL> object has been created using | |
9b86974e RS |
24 | L<SSL_new(3)>, L<SSL_set_fd(3)> or |
25 | L<SSL_set_bio(3)> can be used to associate the network | |
9bd3bd22 | 26 | connection with the object. |
3604a4d3 | 27 | |
cbade361 | 28 | When the TLS/SSL handshake is performed using |
9b86974e | 29 | L<SSL_accept(3)> or L<SSL_connect(3)> |
9bd3bd22 | 30 | respectively. |
7714dc5e MC |
31 | L<SSL_read_ex(3)>, L<SSL_read(3)>, L<SSL_write_ex(3)> and L<SSL_write(3)> are |
32 | used to read and write data on the TLS/SSL connection. | |
9b86974e | 33 | L<SSL_shutdown(3)> can be used to shut down the |
9bd3bd22 | 34 | TLS/SSL connection. |

36 | =head1 DATA STRUCTURES | |
37 | ||
38 | Currently the OpenSSL B<ssl> library functions deals with the following data | |
39 | structures: | |
40 | ||
41 | =over 4 | |
42 | ||
43 | =item B<SSL_METHOD> (SSL Method) | |
44 | ||
cbade361 | 45 | This is a dispatch structure describing the internal B<ssl> library |
45f55f6a KR |
46 | methods/functions which implement the various protocol versions (SSLv3 |
47 | TLSv1, ...). It's needed to create an B<SSL_CTX>. | |
3604a4d3 UM |
48 | |
49 | =item B<SSL_CIPHER> (SSL Cipher) | |
50 | ||
51 | This structure holds the algorithm information for a particular cipher which | |
52 | are a core part of the SSL/TLS protocol. The available ciphers are configured | |
cbade361 | 53 | on a B<SSL_CTX> basis and the actual ones used are then part of the |
3604a4d3 UM |
54 | B<SSL_SESSION>. |
55 | ||
56 | =item B<SSL_CTX> (SSL Context) | |
57 | ||
cbade361 | 58 | This is the global context structure which is created by a server or client |
3604a4d3 UM |
59 | once per program life-time and which holds mainly default values for the |
60 | B<SSL> structures which are later created for the connections. | |
61 | ||
62 | =item B<SSL_SESSION> (SSL Session) | |
63 | ||
37b08e83 | 64 | This is a structure containing the current TLS/SSL session details for a |
3604a4d3 UM |
65 | connection: B<SSL_CIPHER>s, client and server certificates, keys, etc. |
66 | ||
67 | =item B<SSL> (SSL Connection) | |
68 | ||
cbade361 | 69 | This is the main SSL/TLS structure which is created by a server or client per |
3604a4d3 | 70 | established connection. This actually is the core structure in the SSL API. |
cbade361 | 71 | At run-time the application usually deals with this structure which has |
3604a4d3 UM |
72 | links to mostly all other structures. |

76 | |
77 | =head1 HEADER FILES | |
78 | ||
79 | Currently the OpenSSL B<ssl> library provides the following C header files | |
b9b6a7e5 | 80 | containing the prototypes for the data structures and functions: |
9bd3bd22 UM |
81 | |
82 | =over 4 | |
83 | ||
84 | =item B<ssl.h> | |
85 | ||
cbade361 | 86 | This is the common header file for the SSL/TLS API. Include it into your |
9bd3bd22 UM |
87 | program to make the API of the B<ssl> library available. It internally |
88 | includes both more private SSL headers and headers from the B<crypto> library. | |
89 | Whenever you need hard-core details on the internals of the SSL API, look | |
90 | inside this header file. | |
91 | ||
3c5a61dd MR |
92 | OPENSSL_VERSION_AT_LEAST(major,minor) can be |
93 | used in C<#if> statements in order to determine which version of the library is | |
94 | being used. This can be used to either enable optional features at compile | |
95 | time, or work around issues with a previous version. | |
96 | See L<OPENSSL_VERSION_NUMBER(3)>. | |
97 | ||
9bd3bd22 UM |
98 | =item B<ssl2.h> |
99 | ||
87d9cafa | 100 | Unused. Present for backwards compatibility only. |
9bd3bd22 UM |
101 | |
102 | =item B<ssl3.h> | |
103 | ||
cbade361 | 104 | This is the sub header file dealing with the SSLv3 protocol only. |
9bd3bd22 UM |
105 | I<Usually you don't have to include it explicitly because |
106 | it's already included by ssl.h>. | |
107 | ||
9bd3bd22 UM |
108 | =item B<tls1.h> |
109 | ||
cbade361 | 110 | This is the sub header file dealing with the TLSv1 protocol only. |
9bd3bd22 UM |
111 | I<Usually you don't have to include it explicitly because |
112 | it's already included by ssl.h>. | |

502 | SSL_dup() allows applications to configure an SSL handle for use |
503 | in multiple SSL connections, and then duplicate it prior to initiating | |
504 | each connection with the duplicated handle. | |
505 | Use of SSL_dup() avoids the need to repeat the configuration of the | |
506 | handles for each connection. | |
919ba009 VD |
507 | |
508 | For SSL_dup() to work, the connection MUST be in its initial state | |
509 | and MUST NOT have not yet have started the SSL handshake. | |
510 | For connections that are not in their initial state SSL_dup() just | |
511 | increments an internal reference count and returns the I<same> | |
512 | handle. | |
513 | It may be possible to use L<SSL_clear(3)> to recycle an SSL handle | |
514 | that is not in its initial state for re-use, but this is best | |
515 | avoided. | |
516 | Instead, save and restore the session, if desired, and construct a | |
517 | fresh handle for each connection. | |
