Subject: Re: [PATCH V3 6/8] CryptoPkg/BaseCryptLib: Retire HMAC MD5 algorithm
Date: Fri, 8 May 2020 15:03:09 +0000	[thread overview]
Message-ID: <D827630B58408649ACB04F44C510003625A8435C@SHSMSX107.ccr.corp.intel.com> (raw)
In-Reply-To: <20200506235746.19500-7-zhichao.gao@intel.com>

Zhichao,

The removal of AesEcbEncrypt() and AesEcbDecrypt() should go to patch 5.

Regards,
Jian
