# Single SHA256 Brainwallet

For this type of brainwallets, a passphrase is hashed with one iteration of SHA256, and the resulting output is directly used as a 256 bit private key.

The initial collection of Bitcoin addresses presented here is mostly based on passphrases included in the public [privatekeys.pw](https://privatekeys.pw/brainwallet/bitcoin/1) brainwallet list. (Note that we do not endorse this site or its paid services.)
We performed some additional searches for well-known passphrases on top of this initial list.

The Bitcoin addresses represent compressed and uncompressed public keys.
