Please read http://stackoverflow.com/questions/5480131/will-python-systemrandom-os-urandom-always-have-enough-entropy-for-good-crypto

/dev/urandom can indeed run out of entropy if it is called repeatedly.
Here we call it only once, when the wallet is generated, so this cannot happen.

The only risk i see is if your wallet is created as part of the OS install on a very simple device. Correct me if I'm wrong.


Hi Thomas, thank you for this wallet, I have really enjoyed it from an aesthetic perspective so far.

Given that a lot of people are likely to start creating wallets on a very simple device right after an OS install (debian netboot or similar), would it be wise to increase the system entropy somehow and collect randomness in a method similar to that used by GnuPG?

Thanks again for your work with the wallet!

I don't think so.
If the wallet is installed by people, then the system already has some entropy, just because of the way people interact with it.
I would be more concerned about really simple devices (such as the "trezor"), not something able to run a full debian OS, and about seeds generated during that device initialization.
I am not an expert, however; correct me if I'm wrong.
