WebJul 23, 2016 · 4. 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. Web# For EC keys, LE's current Boulder server only supports P-256 and P-384, but may support P-521 in the future. # In all testing so far, the KeySize matches the "P-xxxx" curve name. So we'll just use that to test
