RSA_blinding_on(3) | OpenSSL | RSA_blinding_on(3) |
#include <openssl/rsa.h>
The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):
int RSA_blinding_on(RSA *rsa, BN_CTX *ctx); void RSA_blinding_off(RSA *rsa);
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 preallocated and initialized BN_CTX.
RSA_blinding_off() turns blinding off and frees the memory used for the blinding factor.
RSA_blinding_off() returns no value.
