NOTE: This doesn't fully implement a GUI for the process. This implements the underpinning algorithm and includes a simple tester that does do some encryption, but it’s not “fully baked”. Use at your own risk!

minilockmanaged's Issues

Directory encryption

This requires the use of a Zip library, but I already have one in mind that will work. Since I don't have drag-drop capability yet, implementing that will have to start in the library first, and then in any applications that use the library.

Confirm Read/Write of Files is appropriately buffered to limit memory usage

This was brought up on the main miniLock Git issues list, as the Chrome app actually crashes with large files. The miniLockManaged library that I created should buffer the chunks that are used during encryption/decryption to limit the amount of memory used at any given time. The current decryption output process simply sends a memory stream of data back to the caller for handling. Maybe some overloaded functions are needed and some length checks to force the use of file buffers in files > 100mb.

This should also be expanded to make sure that the Blake2s implementation allows incremental updates so that these in-memory transformations can include the hash and not, at ANY point in the process, require the entire file to be read all at once for large files. Zips are another matter but that can be addressed in the Directory Zipping issue (#2)

Feedback welcome
[edited to include Blake2s hashing]

Invitation to collaborate

Hi Dustin,

This is completely off-topic but I didn't see any better way to contact you, so I beg forgiveness.

I notice that lately you've been very active in the Minilock repo. I have a very similar app (I like to think better ;-) named PassLok, right here on Github. It does pretty much everything Minilock does, plus a lot more. I must confess I've been looking at the Minilock activity looking for ideas, and have implemented a number of them on PassLok (Minilock, apparently, hasn't); this is how I noticed your contribution.

Anyway, I'd be grateful if you could take a look at PassLok and make some more helpful suggestions. I thank you in advance.

SCrypt library causes ContextSwitchDeadlock and seems to never finish (Win 10 Ann. Ed.)

The current library for SCrypt takes far longer to run that it should, causing an exception and seemingly never finishing. A different library should be used, although this might be specific to Windows 10 Anniversary Edition.

Do you have any plans to make this PCL compatible?

I started my own port then found this! I'm pretty sure everything up to key gen can be made PCL (that's where I go to) except perhaps Zxcvdn.dll - I couldn't find a c# port of that.

What's your feeling for the rest - I suspect it should port pretty nicely.

Happy to do a pull and start contributing if you want?

Ta

Ross
