Hello,

Tout d'abord, je suis conscient qu'il ne s'agit pas de la bonne section pour poster ce message, mais je n'ai pas l'option "new post" dans la rubrique "Development & Technical Discussion" et il semble que je ne puisse écrire un message qu'ici... Merci d'avance au modérateur de déplacer ce message au bon endroit.

First of all, I know this is not the place I should be posting this thread, but the "Development & Technical Discussion" section does not allow me to post a new thread! The only place where I can find the "new post" link seems to be there, so sorry for the pollution, and I'd thank the moderator if he'd be kind enough to move this thread to the right place.

Now here is my question:

Is it possible / trivial to compute the public key (or the bitcoin address) from the private key? I haven't studied asymmetric cryptography, but as far as I understand it, the public key is a function of the two secret prime numbers: I would thus guess that the answer to my question is yes.

If that is the case, how should I do it, practically?

Concretely, I want to store my bitcoin wallet information on one QR code. I could very well store both the public/private keys (using the URI format for inst.) but I would prefer storing only the private key in order to reduce the complexity of the QR, if that is possible.

Thank you in advance for your help,

Adrien
