Re: Get ECC Public key from Private key
As the public key is created using the private key, the executed instructions and branches can depend on the private key too. This way an attacker can guess the private key by analysing the power consumption of the device and deduce the executed instruction. That's why I would prefer a built-in, cer...

Re: Get ECC Public key from Private key
Thank you for the answers. I know the "public key = private key * base point" equation but I don't know whether I should do this multiplication or there is built-in methods for this? It's important because my implementation of EC operations might be vulnerable to side-channel attacks. (https://en.wikipedia.org/wiki/Side-channel_attack)

Get ECC Public key from Private key
Hi,
I have a specific private key and I would like calculate it's public key. I'm using 3.0.4 OS and secp256k1 algorithm. Is there any built-in merhod for this?
I succesfully used the KeyPair and KeyBuilder class but it always uses randomly generated private keys.
