PBKDF2-HMAC-SHA2 测试向量 [英] PBKDF2-HMAC-SHA2 test vectors

问题描述

RFC6070 中有 PBKDF2-HMAC-SHA1 的测试向量.RFC4231 中有 HMAC-SHA2 的测试向量.

There are test vectors for PBKDF2-HMAC-SHA1 in RFC6070. There are test vectors for HMAC-SHA2 in RFC4231.

但到目前为止，我还没有在任何地方找到 PBKDF2-HMAC-SHA2 的测试向量.

But so far I haven't found test vectors for PBKDF2-HMAC-SHA2 anywhere.

我对 SHA256 最感兴趣，所以我将发布一些我用我的实现计算的向量.如果有人可以验证/确认他们，或者贡献他们自己的，我会很高兴.

I'm most interested in SHA256, so I'll post some vectors I calculated with my implementation. I'd be happy if someone could verify/confirm them, or contribute their own.

推荐答案

我 使用标准 hashlib 和 hmac Python 中的模块，并根据 RFC 6070 向量和 您发布的向量 - 匹配.

I implemented PBKDF2 using the standard hashlib and hmac modules in Python and checked the output against both the RFC 6070 vectors and the vectors you posted – it matches.

这是我使用较大的 dkLen 获得的向量，以匹配较大的摘要输出大小.这是pbkdf2-test-vectors.py sha256的输出，运行大约需要10分钟.

Here are the vectors I get with a larger dkLen to match the larger digest output size. This is the output of pbkdf2-test-vectors.py sha256, which takes about 10 minutes to run.
