I attended a meeting at Microsoft the other day at which they described their Crypto API project. As CAPIs go, it's reasonable enough; nothing particularly exciting about it or especially wrong with it (though they don't yet support nonblocking calls to crypto modules).

...

...

We received several requests at the design review to add non-blocking calls. We're looking to add this.

... They have (or will have soon) an application development kit to allow you to write code that uses the API, and a CSP development kit to let you write the crypto functions.

...

...

Doc's and sample code from the SDK are available now on our web page: http://www.microsoft.com/intdev/inttech/cryptapi.htm. Please e-mail cryptapi@microsoft.com if you're interested in a CSP development kit.

...One important issue is whether MS will really sign anyone's CSP or whether they will start charging high fees or making business-based decisions on who's CSPs they will allow (with they sign Netscape's CSP, for example). They say they won't even look or keep a copy of your CSP (at my suggestion, they are probably going to change the process so that you send them a hash of your CSP instead of your CSP code when you get the signature). For now they promise to sign CSPs for anyone who returns the export certificate, at no charge.

...

...

We won't charge high fees (right now, it's free!). Our policy is simple: we'll sign the CSP of anyone who follows the rules. Yes, we would sign a CSP from Netscape if they follow the rules. We won't look at or keep a copy of the CSP, and we won't tell your competitors about it (unless you ask us to).

... They say that the API kit will not be export-controlled but the CSP kit will be.

...

...

The SDK is not export-controlled. The CSP development kit is export-controlled.
