ETFbitcoin: you're arguing for the sake of arguing. I have clearly stated, both in my OP and in my second post I haven't used any state of the art (or any at all, actually) encryption method. Any penetration tester, ethical (or not-so-ethical) hacker, or computer security expert knows how to crack a string, you don't need to be Ralph Merkle to do it.
And I don't know what a "black box protocol" is, so maybe I'm using it, maybe I'm not.
- No encryption algorithm has been used.
I have used a childish method (writing the words backwards), together with translating each words into my native language (Spanish), and finally inserting said words into the first verse of what is arguably the absolute best known Argentinian classic of all times: "Martín Fierro", by José Hernández. I have known that book (and its first verse by memory) since I was 9 (and I'm turning 57 today, so it's been a long time), so the chances of me forgetting it are... well... nil.

It's not encrypted. There's no hash to forget.
