RSA_BLINDING_ON(3)		    OpenSSL		    RSA_BLINDING_ON(3)

NAME
       RSA_blinding_on,	RSA_blinding_off - protect the RSA operation from
       timing attacks

SYNOPSIS
	#include <openssl/rsa.h>

	int RSA_blinding_on(RSA	*rsa, BN_CTX *ctx);

	void RSA_blinding_off(RSA *rsa);

DESCRIPTION
       RSA is vulnerable to timing attacks. In a setup where attackers can
       measure the time	of RSA decryption or signature operations, blinding
       must be used to protect the RSA operation from that attack.

       RSA_blinding_on() turns blinding	on for key rsa and generates a random
       blinding	factor.	ctx is NULL or a pre-allocated and initialized BN_CTX.

       RSA_blinding_off() turns	blinding off and frees the memory used for the
       blinding	factor.

RETURN VALUES
       RSA_blinding_on() returns 1 on success, and 0 if	an error occurred.

       RSA_blinding_off() returns no value.
