There was a problem hiding this comment.
Thanks for this. I'm pretty sure we don't need the new encrypt.Zero given encode.ClearBytes.
I would not be opposed to dex/encrypt/encrypt.go defining type Zero = encode.ClearBytes to smooth some stuff out, but if a package is already importing dex/encode, there's really no need to use encrypt.

Just rebased. |
In core methods and consumers, clear passwords, private keys, and seeds when possible to protect against some memory scraping attacks.

lightly discussed in #1582
This pr makes it so the crypter cannot be used in goroutines. I think we're not doing so atm, but should be careful going forward.
