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.

Richard Levitte authored
(that is, until 1.2.0 comes along) Since we allow future deprecation (and that shouldn't be affected by 'no-deprecated'), we need to distinguish what to have deprecated on the value of OPENSSL_API_COMPAT, not the existence of OPENSSL_NO_DEPRECATED. Note that the macro OPENSSL_NO_DEPRECATED still exists, in case someone still uses it. Reviewed-by:

This commit replaces the certificates in demos/bio with new certificates that don't expire until 2118. The same certificates appear in both demos/smime and demos/cms. This commit copies the new certificates and keys from demos/smime to demos/cms. This PR Fixes #6412 by updating cacert.pem and signer.pem in the openssl/demos/smime/ directory. It also updates all of the keys with longer key lengths. Reviewed-by:

Keegan Ryan (NCC Group) has demonstrated a side channel attack on an ECDSA signature operation. During signing the signer calculates: s:= k^-1 * (m + r * priv_key) mod order The addition operation above provides a sufficient signal for a flush+reload attack to derive the private key given sufficient signature operations. As a mitigation (based on a suggestion from Keegan) we add blinding to the operation so that: s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order Since this attack is a localhost side channel only no CVE is assigned.
