+.Vb 1
+\& #include <openssl/rsa.h>
+.Ve
+.PP
+The following functions have been deprecated since OpenSSL 3.0, and can be
+hidden entirely by defining \fBOPENSSL_API_COMPAT\fR with a suitable version value,
+see \fBopenssl_user_macros\fR\|(7):
+.PP
+.Vb 1
+\& int RSA_blinding_on(RSA *rsa, BN_CTX *ctx);
+\&
+\& void RSA_blinding_off(RSA *rsa);
+.Ve
+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+All of the functions described on this page are deprecated.
+.PP
+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.
+.PP
+\&\fBRSA_blinding_on()\fR turns blinding on for key \fBrsa\fR and generates a
+random blinding factor. \fBctx\fR is \fBNULL\fR or a preallocated and
+initialized \fBBN_CTX\fR.
+.PP
+\&\fBRSA_blinding_off()\fR turns blinding off and frees the memory used for
+the blinding factor.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBRSA_blinding_on()\fR returns 1 on success, and 0 if an error occurred.
+.PP
+\&\fBRSA_blinding_off()\fR returns no value.
+.SH HISTORY
+.IX Header "HISTORY"
+All of these functions were deprecated in OpenSSL 3.0.
