Implement coordinate blinding for EC_POINT.

2018-11-05T20:18:21+00:00

Based on OpenSSL commit 875ba8b21ecc65ad9a6bdc66971e50 by Billy Brumley, Sohaib ul Hassan and Nicola Tuveri. ok beck jsing commit 875ba8b21ecc65ad9a6bdc66971e50461660fcbb Author: Sohaib ul Hassan Date: Sat Jun 16 17:07:40 2018 +0300 Implement coordinate blinding for EC_POINT This commit implements coordinate blinding, i.e., it randomizes the representative of an elliptic curve point in its equivalence class, for prime curves implemented through EC_GFp_simple_method, EC_GFp_mont_method, and EC_GFp_nist_method. This commit is derived from the patch https://marc.info/?l=openssl-dev&m=131194808413635 by Billy Brumley. Coordinate blinding is a generally useful side-channel countermeasure and is (mostly) free. The function itself takes a few field multiplicationss, but is usually only necessary at the beginning of a scalar multiplication (as implemented in the patch). When used this way, it makes the values that variables take (i.e., field elements in an algorithm state) unpredictable. For instance, this mitigates chosen EC point side-channel attacks for settings such as ECDH and EC private key decryption, for the aforementioned curves. For EC_METHODs using different coordinate representations this commit does nothing, but the corresponding coordinate blinding function can be easily added in the future to extend these changes to such curves.

Explicitly export a list of symbols from libcrypto.

2016-12-21T15:49:29+00:00

Move the "internal" BN functions from bn.h to bn_lcl.h and stop exporting the bn_* symbols. These are documented as only being intended for internal use, so why they were placed in a public header is beyond me... This hides 363 previously exported symbols, most of which exist in headers that are not installed and were never intended to be public. This also removes a few crusty old things that should have died long ago (like _ossl_old_des_read_pw). But don't worry... there are still 3451 symbols exported from the library. With input and testing from inoguchi@. ok beck@ inoguchi@
