Did you use any non-ascii character in the password? If so, which?

The decryption error listed in this issue suggest it an invalid password issue.

The official [pyethsaletool](https://github.com/ethereum/pyethsaletool) uses PKCS7 padding, which this library replicates. There are no changes in the code for this in 0.6.3. It will be impossible to pinpoint any possible issue...

One version of the tool used a slightly different derivation, though I do not think that was the final one. Maybe you have used it though. Added a branch here:...

What system are you trying to run this on?

I'm not fully sure what problem this is solving, since the key is not cleared from memory.

I am just confused what benefit this gives. If a user of this library can call `.flush()` cannot they just invalidate references to the wallet?

@yann300 @chriseth any comments/ideas on designing this? The main goal is to have a more flexible interface (and the ability to decode/encode more complex types) as well as to avoid...

@vrolland thanks for the PR! Can you please explain the feature?

Oh I see, thanks, it makes sense. I'd prefer to have the two changes separate and lets tackle the support for array first here. I think instead of code duplication...
