ssl(3)                              OpenSSL                             ssl(3)

       SSL - OpenSSL SSL/TLS library

       The OpenSSL ssssll library implements the Secure Sockets Layer (SSL v2/v3)
       and Transport Layer Security (TLS v1) protocols. It provides a rich API
       which is documented here.

       At first the library must be initialized; see SSL_library_init(3).

       Then an SSSSLL_CCTTXX object is created as a framework to establish TLS/SSL
       enabled connections (see SSL_CTX_new(3)).  Various options regarding
       certificates, algorithms etc. can be set in this object.

       When a network connection has been created, it can be assigned to an
       SSSSLL object. After the SSSSLL object has been created using SSL_new(3),
       SSL_set_fd(3) or SSL_set_bio(3) can be used to associate the network
       connection with the object.

       Then the TLS/SSL handshake is performed using SSL_accept(3) or SSL_con-
       nect(3) respectively.  SSL_read(3) and SSL_write(3) are used to read
       and write data on the TLS/SSL connection.  SSL_shutdown(3) can be used
       to shut down the TLS/SSL connection.

       Currently the OpenSSL ssssll library functions deals with the following
       data structures:

           That's a dispatch structure describing the internal ssssll library
           methods/functions which implement the various protocol versions
           (SSLv1, SSLv2 and TLSv1). It's needed to create an SSSSLL_CCTTXX.

           This structure holds the algorithm information for a particular
           cipher which are a core part of the SSL/TLS protocol. The available
           ciphers are configured on a SSSSLL_CCTTXX basis and the actually used
           ones are then part of the SSSSLL_SSEESSSSIIOONN.

       SSSSLL_CCTTXX (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 SSSSLL structures which are later created for the con-

           This is a structure containing the current TLS/SSL session details
           for a connection: SSSSLL_CCIIPPHHEERRs, client and server certificates,
           keys, etc.

       SSSSLL (SSL Connection)
           That's the main SSL/TLS structure which is created by a server or
           client per established connection. This actually is the core struc-
           ture in the SSL API.  Under run-time the application usually deals
           with this structure which has links to mostly all other structures.

       Currently the OpenSSL ssssll library provides the following C header files
       containing the prototypes for the data structures and and functions:

           That's the common header file for the SSL/TLS API.  Include it into
           your program to make the API of the ssssll library available. It
           internally includes both more private SSL headers and headers from
           the ccrryyppttoo library.  Whenever you need hard-core details on the
           internals of the SSL API, look inside this header file.

           That's the sub header file dealing with the SSLv2 protocol only.
           Usually you don't have to include it explicitly because it's
           already included by ssl.h.

           That's the sub header file dealing with the SSLv3 protocol only.
           Usually you don't have to include it explicitly because it's
           already included by ssl.h.

           That's the sub header file dealing with the combined use of the
           SSLv2 and SSLv3 protocols.  Usually you don't have to include it
           explicitly because it's already included by ssl.h.

           That's the sub header file dealing with the TLSv1 protocol only.
           Usually you don't have to include it explicitly because it's
           already included by ssl.h.

       Currently the OpenSSL ssssll library exports 214 API functions.  They are
       documented in the following:


       Here we document the various API functions which deal with the SSL/TLS
       protocol methods defined in SSSSLL_MMEETTHHOODD structures.

       SSL_METHOD *SSSSLLvv22_cclliieenntt_mmeetthhoodd(void);
           Constructor for the SSLv2 SSL_METHOD structure for a dedicated

       SSL_METHOD *SSSSLLvv22_sseerrvveerr_mmeetthhoodd(void);
           Constructor for the SSLv2 SSL_METHOD structure for a dedicated

       SSL_METHOD *SSSSLLvv22_mmeetthhoodd(void);
           Constructor for the SSLv2 SSL_METHOD structure for combined client
           and server.

       SSL_METHOD *SSSSLLvv33_cclliieenntt_mmeetthhoodd(void);
           Constructor for the SSLv3 SSL_METHOD structure for a dedicated

       SSL_METHOD *SSSSLLvv33_sseerrvveerr_mmeetthhoodd(void);
           Constructor for the SSLv3 SSL_METHOD structure for a dedicated

       SSL_METHOD *SSSSLLvv33_mmeetthhoodd(void);
           Constructor for the SSLv3 SSL_METHOD structure for combined client
           and server.

       SSL_METHOD *TTLLSSvv11_cclliieenntt_mmeetthhoodd(void);
           Constructor for the TLSv1 SSL_METHOD structure for a dedicated

       SSL_METHOD *TTLLSSvv11_sseerrvveerr_mmeetthhoodd(void);
           Constructor for the TLSv1 SSL_METHOD structure for a dedicated

       SSL_METHOD *TTLLSSvv11_mmeetthhoodd(void);
           Constructor for the TLSv1 SSL_METHOD structure for combined client
           and server.


       Here we document the various API functions which deal with the SSL/TLS
       ciphers defined in SSSSLL_CCIIPPHHEERR structures.

       char *SSSSLL_CCIIPPHHEERR_ddeessccrriippttiioonn(SSL_CIPHER *cipher, char *buf, int len);
           Write a string to buf (with a maximum size of len) containing a
           human readable description of cipher. Returns buf.

       int SSSSLL_CCIIPPHHEERR_ggeett_bbiittss(SSL_CIPHER *cipher, int *alg_bits);
           Determine the number of bits in cipher. Because of export crippled
           ciphers there are two bits: The bits the algorithm supports in gen-
           eral (stored to alg_bits) and the bits which are actually used (the
           return value).

       const char *SSSSLL_CCIIPPHHEERR_ggeett_nnaammee(SSL_CIPHER *cipher);
           Return the internal name of cipher as a string. These are the vari-
           ous strings defined by the SSL2_TXT_xxx, SSL3_TXT_xxx and
           TLS1_TXT_xxx definitions in the header files.

       char *SSSSLL_CCIIPPHHEERR_ggeett_vveerrssiioonn(SSL_CIPHER *cipher);
           Returns a string like ""TLSv1/SSLv3"" or ""SSLv2"" which indicates
           the SSL/TLS protocol version to which cipher belongs (i.e. where it
           was defined in the specification the first time).
