Description
RWSecureSocketMethod encapsulates the various TLS/SSL protocol versions. An instance of this class is required to construct an RWSecureSocketContext<rwsecuresocketcontext.html> object.
The Secure Sockets package used to provide a static instance of this class for each available TLS/SSL protocol version. Unfortunately, this solution suffered from static initialization order problems when global instances of RWSecureSocketContext were used. We replaced the static instances with identically named static pointers to the corresponding underlying cryptography library functions, and added a constructor that converts these pointers to functions into RWSecureSocketMethod instances. This change allows code previously written to function identically with no code changes, and only a recompile.
The following table lists the provided static function pointers:
Table 5: RWSecureSocketMethod Static Function Pointers
| Static Constant Name | TLS or SSL Version |
TLSv1WithFallback | TLS version 1, either side of protocol, with fallback to SSL version 3, and then SSL version 2. This is the default when creating RWSecureSocketContext objects. |
TLSv1ClientWithFallback | TLS version 1, client side only, with fallback to SSL version 3, and then SSL version 2. |
TLSv1ServerWithFallback | TLS version 1, server side only, with fallback to SSL version 3, and then SSL version 2. |
TLSv1 | TLS version 1 only, either side of protocol. |
TLSv1Client | TLS version 1 only, client side only. |
TLSv1Server | TLS version 1 only, server side only. |
SSLv3 | SSL version 3 only, either side of protocol. |
SSLv3Client | SSL version 3 only, client side only. |
SSLv3Server | SSL version 3 only, server side only. |
SSLv2 | SSL version 2 only, either side of protocol. |
SSLv2Client | SSL version 2 only, client side only. |
SSLv2Server | SSL version 2 only, server side only. |
Public Constructor
RWSecureSocketMethod( SSL_METHOD *meth );
Throws RWSecureSocketInvalidMethodError if meth is NULL. You will not normally use this constructor directly.
Public Operator
operator SSL_METHOD*() const;
Conversion operator.
