# 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 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. Due to the nature of brainwallets, the collection is not exhaustive.
