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));
