+ * rsa-sign-tr.c (rsa_sec_compute_root_tr): New function that uses
+ _rsa_sec_compute_root, as well as side-channel silent RSA
+ blinding.
+ (rsa_compute_root_tr) Rewritten as a wrapper around
+ rsa_sec_compute_root_tr.
+ (rsa_sec_blind, rsa_sec_unblind, sec_equal, rsa_sec_check_root)
+ (cnd_mpn_zero): New helper functions.
+ (rsa_sec_compute_root_tr) [NETTLE_USE_MINI_GMP]: Defined as a not
+ side-channel silent wrapper around rsa_compute_root_tr, and the
+ latter function left unchanged.
+
* rsa-sec-compute-root.c (_rsa_sec_compute_root_itch)
(_rsa_sec_compute_root): New file, new private functions.
Side-channel silent version of rsa_compute_root.
