- Fix potential memory overread when performing an ECDSA signature
operation. The overread only happens with cryptographically low
probability (of the order of 2^-n where n is the bitsize of the
curve) unless the RNG is broken, and could result in information
disclosure or denial of service (application crash or extra resource
consumption).
- To avoid a side channel vulnerability when parsing an RSA private
key, read all the CRT parameters from the DER structure rather than
reconstructing them.
- Update indentation of hash file (two spaces)

Committed to 2019.11.x, thanks.
For 2019.02.x I will instead bump to 2.7.14.
