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.
