NetBSD 6.1.5 - man page for rsa_blinding_on (netbsd section 3)

RSA_blinding_on(3)			     OpenSSL			       RSA_blinding_on(3)

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

LIBRARY
       libcrypto, -lcrypto

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. The random number generator must be
       seeded prior to calling RSA_blinding_on().

       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.

SEE ALSO
       openssl_rsa(3), openssl_rand(3)

HISTORY
       RSA_blinding_on() and RSA_blinding_off() appeared in SSLeay 0.9.0.
