From 9396cdfeaa7a053093c9d0a1f13ef6d672dfaa9f Mon Sep 17 00:00:00 2001 From: Jiaxin Wu Date: Wed, 14 Dec 2016 10:34:57 +0800 Subject: [PATCH 1/1] CryptoPkg: Add new TlsLib library v2: * Code refine and Typo fix: TlsHandeAlert -> TlsHandleAlert This patch is used to add new TlsLib library, which is wrapped over OpenSSL. The implementation provides TLS library functions for EFI TLS protocol and EFI TLS Configuration Protocol.
