Updated Botan to 2.14.0 which includes multiple big fixes and TLS updates.
Summarized Changelog:

  • Add support for using POWER8+ VPSUMD instruction to accelerate GCM
  • Optimize the vector permute AES implementation, especially improving performance on ARMv7, Aarch64, and POWER.
  • Use a new algorithm for modular inversions which is both faster and more resistant to side channel attacks.
  • Optimize NIST prime field reductions, improving ECDSA by 3-9%.
  • Add server side support for the TLS asio wrapper.
  • Fix a bug which prevented using DER-encoded ECDSA signatures with a PKCS11 key.
  • Fix some build problems under Intel C++
  • Work around a GCC bug affecting old libc.
Test Plan

Ran all tests includes with the source. All tests passed and everything functioned as expected.

I just saw scrolling through recent patches that EbonJaeger already submitted a patch to update this a few days ago with D8749. Apologies on the duplicate patch.
