- Fix CVE-2019-14318: Crypto++ 8.2.0 and earlier contains a timing side
channel in ECDSA signature generation. This allows a local or remote
attacker, able to measure the duration of hundreds to thousands of
signing operations, to compute the private key used. The issue occurs
because scalar multiplication in ecp.cpp (prime field curves, small
leakage) and algebra.cpp (binary field curves, large leakage) is not
constant time and leaks the bit length of the scalar among other
information. For details, see:

- Update license hash due to the addition of ARM SHA1 and SHA256 asm
implementation from Cryptogams
