 "Function Documentation"

 "void RSA_free (RSA * rsa)"
Free an allocation RSA object.

Parameters

rsa the RSA object to free.


 "void* RSA_get_app_data (const RSA * rsa)"
Get the application data for the RSA object.

Parameters

rsa the rsa object to get the parameter for


Returns

the data object


 "const RSA_METHOD* RSA_get_method (const RSA * rsa)"
Return the RSA_METHOD used for this RSA object.

Parameters

rsa the object to get the method from.


Returns

the method used for this RSA object.


 "RSA* RSA_new (void)"
Same as RSA_new_method() using NULL as engine.

Returns

a newly allocated RSA object. Free with RSA_free().


 "RSA* RSA_new_method (ENGINE * engine)"
Allocate a new RSA object using the engine, if NULL is specified as the engine, use the default RSA engine as returned by ENGINE_get_default_RSA().

Parameters

engine Specific what ENGINE RSA provider should be used.


Returns

a newly allocated RSA object. Free with RSA_free().


 "int RSA_set_app_data (RSA * rsa, void * arg)"
Set the application data for the RSA object.

Parameters

rsa the rsa object to set the parameter for

arg the data object to store


Returns

1 on success.


 "int RSA_set_method (RSA * rsa, const RSA_METHOD * method)"
Set a new method for the RSA keypair.

Parameters

rsa rsa parameter.

method the new method for the RSA parameter.


Returns

1 on success.


 "int RSA_up_ref (RSA * rsa)"
Add an extra reference to the RSA object. The object should be free with RSA_free() to drop the reference.

Parameters

rsa the object to add reference counting too.


Returns

the current reference count, can't safely be used except for debug printing.
