Error on relatively large iteration counts

[alecmev]

This works fine:

scrypt.kdfSync('abc', { N: 16, r: 8, p: 1 })

While this doesn't:

scrypt.kdfSync('abc', { N: 16384, r: 8, p: 1 })

Throws error computing derived key. Clearly, this is a local problem, since 16384 isn't even large, it's normal, but how do I troubleshoot this? I'm running this inside a vanilla Node 6.0.0 Docker container, if that's of any relevance.

This looks like an error. Thanks for bringing it to my attention. I will have a fix out shortly.

The problem is that the KDF function expects parameters that have been passed to it via the params functions. So what it is expecting if you pass it a straight {N, r, p} object is for the N to be logarithmic. So if you substitute 14 for N (because 2^14 = 16384), it should work fine.

Still, I see where the confusion comes in, and when using a raw object like you have, it should not do this. I will try roll out a fix ASAP.

Can we be notified for when this will be fixed?

Would this be a breaking change or a new function ?

I am trying to have a fix out within the month. The only problem is that it may be a breaking change. Trying to figure out how to get round this...
