🌬️🎙️ seed_entropy_blower 🎲🗝

blow into your mic to generate some entropy.

use that entropy to create a BIP39 seed phrase.

principle

f32 samples are collected from the audio input for 10 seconds and turned into an array of raw bytes, which is used as a sha256 preimage.

the 32 bytes from the sha256 hash are used as entropy for generating a BIP39 seed phrase of 24 words.

⚠️ warning⚠️

the author holds no liability in case you lose your coins.

use this tool at your own risk, ideally if you can read the source code and understand what it is doing.
