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

问题描述

我需要为Amazon Web服务API生成HMAC-SHA256签名。旧的DCPcrypt库具有sha256例程，但不进行HMAC签名。任何人都知道可以使用的免费散列图书馆？

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

经过多一点搜索，我发现OpenStreamSec - 它看起来像几年前被遗弃，但仍在D2007中编译。

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

为Amazon生成HMAC-256非常简单：

Generating a HMAC-256 for Amazon is really simple:

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