How does a bitcoin brain wallet generator work?

Typically, any Bitcoin brain wallet generator allows its users to key in random words (i.e. 4,6,8,12, or 24 words long) which is called a passphrase. This passphrase, depending upon the type of generator you are using, is hashed with SHA-256 or the Scrypt algorithm to generate a Bitcoin private key and then a Bitcoin public key.
