curve25519: mask high bit when loading group point Comparison against BoringSSL-generated test vectors showed mismatches with the pure Go implementation of curve25519. The problem was narrowed down to a missing mask in feFromBytes(). This diff adds the mask, bringing this back in line with the reference implementation and RFC 7748: When receiving such an array, implementations of X25519 (but not X448) MUST mask the most significant bit in the final byte. This is done to preserve compatibility with point formats that reserve the sign bit for use in other protocols and to increase resistance to implementation fingerprinting.
