WebJan 23, 2024 · Of course you can use Elliptic Curve cryptography to do public key encryption, that is, a method with a public key and a private key; anyone with the public key can encrypt, but only someone with the private key can decrypt. One way would be to use the Integrated Encryption System. WebJul 29, 2024 · Public keys in ECDSA are expressed as a co-ordinate on the curve, i.e. an x and a y value. As you say 0x04 indicates the key is in uncompressed format, meaning the whole x and y values are given - each of which are 32 bits in length. – Matt Caswell Jul 30, 2024 at 8:12 Add a comment Your Answer Post Your Answer
