HMAC-SHA256德尔福 [英] HMAC-SHA256 in Delphi

问题描述

我需要生成HMAC-SHA256签名亚马逊Web服务的API。老DCPcrypt库有SHA256程序，但没有做HMAC签名。任何人都知道的免费哈希库，我可以用？

I need to generate HMAC-SHA256 signatures for the Amazon web services API. The old DCPcrypt library has sha256 routines but does not do HMAC signing. Anyone know of a free hashing library I could use?

推荐答案

多一点搜索，我发现OpenStreamSec后 - 这看起来像是被遗弃在几年前，但仍然在编译D2007

After a little more searching I found OpenStreamSec - which looks like it was abandoned a few years ago but still compiles in D2007.

生成HMAC-256亚马逊是非常简单的：

Generating a HMAC-256 for Amazon is really simple:

StrToMime64(HMACString(haSHA256, SecretKey, 32, DataToHash));
