In secp256r1 they are supposedly from random numbers, however, it is impossible to prove that's really the case. See e.g. these slides from Bernstein and Lange for an easily understandable treatment. The Koblitz curve, on the other hand, has had its parameters chosen relatively rigidly. The post runeks linked in the comments has an explanation for why they were chosen. So rather than saying. points on curve secp256k1 form a group E(Fp) over field Fp. p = 2^256 - 2^32 - 2^9 - 2^8 - 2^7 - 2^6 - 2^4 - 1 is prime. n is the order of group E, n

ECDSA in JavaScript: secp256k1-based sign / verify

This is possibly a dumb question. I'm trying to input SECP256K1 curve parameters to a system that expects any custom curve. The form is asking for curve type. It offers three options: Shor In this example, I am using prime256v1 (secp256r1), which is suitable for JWT signing; this is the curve used for JOSE's ES256. You can now generate a private key: openssl ecparam -name prime256v1 -genkey -noout -out private-key.pem. This should give you a PEM file containing your EC private key, which looks something like the following The microsoft libraries support only P-256, P-384 and P-521 NIST-recommended elliptic curve ID, that is the equivalent named curve, rispectively, secp256r1, secp384r1, secp521r1 of SEC 2 recommended elliptic curve domain parameters that are the equivalent of prime256v1, but not 384 and 521 in ANSI X9.62 ECDSA prime curve ID.

We could still rely on the hardware backed APIs to evaluate the key derivation function and as a source of high-quality randomness.

That being said, the one curve that is supported everywhere is NIST's curve P-256, also known as secp256r1 or prime256r1 (not to be confused with secp256k1, which is a distinct curve). The NIST curve P-384 also has a fair share of widespread support, although maybe not as much as P-256. Also, P-384 implies a bit more computational work (about three times as much), which does not matter. Basic secp256r1 signature using PRO2. Nitrokey Support. English.
