I would suggest this to avoid losing coins.
1. Use SHA256 of your document as a private key.
2. Send some money (e.g. 0.01 BTC) to the address created from that private key.
3. Wait till it is well confirmed and "old enough" (to avoid paying antispam fee).
4. Send that money back to your private address.
5. Reveal your SHA256 to the world.
