Isis Lovecruft	ce2260afab	Implement stricter scalar malleability checking for signatures. ... Previously, we were checking that the highest 3 bits were unset, which still leaves 2^253 - 2^252 + 27742317777372353535851937790883648493 potential scalars for the `s` component of a signature which are not strictly mod \ell. This change fixes that. Note: This change makes ed25519-dalek incompatible with ed25519-donna in that some signatures produced by donna will be verifiable by donna but NOT VERIFIABLE by dalek. On the other hand, libsodium exports a -DED25519_COMPAT feature, which when enabled, means it is compatible with dalek with the `legacy_compatibility` feature disabled. Otherwise, libsodium's behaviour is identical to the behaviour enabled by default in this patch.	2019-10-04 19:34:00 +00:00
