say I have this private key: 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf
Now let's say I take the 5 out then take any location of this string and flip it: bpvD8s5ip4nEB3kEsreAnchuDf HpHagT65TZzG1PH3CSu63k8D
(I kept the space to make it easier to see. merged would look like this: bpvD8s5ip4nEB3kEsreAnchuDfHpHagT65TZzG1PH3CSu63k8D)
Now I send this to myself on an e-mail.
How easy would it be to reverse this string to the original privkey if you knew my recipe? (1. remove first char, 2. split key anywhere and flip)
