speed of the NIST P-384 elliptic curve. To enable the implementation
|

the build option `enable-ec_nistp_64_gcc_128` must be used.

* Reworked the Fix for the Timing Oracle in RSA Decryption ([CVE-2022-4304]).
|

The previous fix for this timing side channel turned out to cause
|

a severe 2-3x performance regression in the typical use case

compared to 3.0.7. The new fix uses existing constant time

code paths, and restores the previous performance level while
