How to make a brain wallet out of any private key.
Think of a common name for each letter in the private key. If the letter is upper case use a male name if the letter is lower case use a female name. If the character is a number use the number because numbers are easy to remember. Thus the private key:
5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf
Is:
5 Henry Patty Henry Agatha Gail Tom 65 Tom Zak Zoey Gale 1 Peter Henry 3 Charles Sam Ursula 63 Kathy 8 Denis Betty Patty Victoria Dennis 8 Sally 5 Irene Patty 4 Nancy Ernie Bob 3 Kathy Ernie Sally Renie Ester Archie Nancy Catherine Helen Ursula Dennis Fanny
This simple rule makes any private key easy to remember. Tell everyone you trust your private key name. This is a backup against you forgetting.
This method is very sexist.
And racist!
