WebJul 23, 2016 · ECC public keys are (X,Y) points where X and Y are elements in a given field (e.g. Fp or F2m). For example, secp160r1 uses a 160-bit prime field. X and Y can be up to 160 bits long. So (X,Y) is 320 bits. The (X,Y) point can be represented in compressed form where only the X value and a bit of information is given, since Y is a function of X. therapiedecke 155x220WebPublicKey : Cryptocurrencies like Bitcoin or Litecoin, etc uses the Elliptic Curve (EC) to calculate the public keys.
