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.

"WebSep 20, 2024 · Elliptic Curve Cryptography(ECC) is based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was independently suggested by Neal Koblitz and Victor Miller in 1985. From a high level, Crypto++ offers a numbers of schemes and alogrithms which operate over elliptic curves. " - Crypto.publickey.ecc
