Title: ELECTRUM URANDOM VULNERABLE ON TAILS
Post by: Book672 on December 30, 2015, 12:21:52 PM
Hi guys, i store a big stash of bitcoins that i earned from altcoin trading, on Tails.

I noticed that Electrum uses urandom function of the linux package.

But TAILS is having a problem with that:

Is it safe to use ELECTRUM in TAILS?

From what I can read in this github comment (https://github.com/spesmilo/electrum/issues/507#issuecomment-105292827) Tails fixes the entropy problem by using haveged (http://www.issihosts.com/haveged/)

So you should be ok.

No its, not because it uses the same seed every time.

I`m also concerned about this ,especially in weakened hardware processors.

If you are concerned just move the bitcoin to a good hardware wallet like Trezor.

`/dev/random` and `/dev/urandom` are the best sources of entropy on a PC. Any other technique can only match them or do worst.
