Nice, interesting, sleek, fun and cheap service at only about $1 and it generated a pdf at the end with all the details!
Why the SHA3 digestion algorithm that lacks the long and still perfect track record of SHA2 though?
Thanks for the good feedback! We appreciate your custom.
We went for SHA3 as it is most likely future proof, it is the winner of the NIST hash function competition and the SHA-3 standard was released by NIST on August 5, 2015.
SHA3 is also not susceptible to length extension attacks which other algorithms including SHA2 are.
Just an FYI if you sign a message with the bitcoin address used to send payment to our system and include it on the second step this will also be included in your PDF at the end!
I really like the setup of this system... I really like the fact that even if your company disappears, i'll still be able to proof ownership of any digital work i've done...
I'll consider using your service the next time i write a script for which the buyer doesn't buy all rights (so he doesn't have the right to redistribute my work)...
That's correct, your crypto-proof will be around for as long as Bitcoin is! And we have the advantage of using the latest hashing function to ensure your crypto-proof will be secure in the future.
