Rijndael algo. available in MS Crypto API?

[Sean Kelly]

The old one, not the .NET version. I don't see it listed, but since
it's available under .NET I thought I'd ask. Also, there are some API
calls which are supposedly not available under most Windows
installations (CryptBinaryToString, for example). I don't suppose this
has changed? Basically, I'm trying to replicate the functionality of
some .NET crypto stuff in C++ and finding that some of the stuff I need
isn't available.

Sean,

I believe it's available - MS_ENH_RSA_AES_PROV.

I believe it's available - MS_ENH_RSA_AES_PROV

Thanks! Looks like it is in the header. Just no mention of it in the docs.

Sean,

I believe it's available - MS_ENH_RSA_AES_PROV.

Sounds right.

If that's not the algo you want, you could always use a library like
Crypto++ (http://sourceforge.net/cvs/?group_id=6152), which definitely
implements Rijndael.

I believe it's available - MS_ENH_RSA_AES_PROV.

That provider is available only in XP (and 2003, I guess) - unless
MS have sneaked into an SP for Win2k without my noticing.

Technically, of course, CryptoAPI supports every algorithm you've
ever thought of - you just have to write a CSP to provide it.
MS_ENH_RSA_AES_PROV is just the only provider (I know of) that
comes with Windows and supports AES. I'm quite sure there are
3rd-party CSPs from security hardware vendors that support it too.

Cheers,
Daniel.
