Deterministic ID key creation

Deterministic GPG brainwallet

Deterministic GPG key creation. Idea prompted by electrum and DJB's blog Entropy Attacks.

Use case: Anyone who needs a secure yet ephemeral workstation and needs to do some cryptography. For example: a TAILS. This could also be helpful for the person with a good memory but a bad track record of losing data.

Requirements

• GPG
• Electrum (optional)
• MonkeySphere
• PyCrypto

How to use

python deterministicgpg.py

Then enter Name, Email, and passphrase or Electrum seed.

Issues

1. Is my deterministic random number generator cryptographically secure? Evidence in favor: the method used is also used in the python ecdsa.util.PRNG.
2. Is PyCrypto's RSA key generation correct?

Future

• Electrum plugin built into GUI
• Option to generate keys off of electrum private keys (is this helpful in any way?)
• Non-RSA keys?
• Set trust on generated gpg keys
• Anything else we should deterministically generate? Bit-message IDs?
