Websecp256k1 has characteristic p, it is defined over the prime field ℤ p.

As the a … WebDec 2, 2024 · It turns out that for secp256k1 n is a prime. Now we know by Lagrange's Theorem the order of any subgroup (like the subgroup generated by G) of secp256k1 must divide n, so either have 1 or n elements. But the only element that generates a subgroup with one element is O (because O + O = O) and thus G must have order n.

WebFeb 2, 2024 · For both P-256 and secp256k1, a public key is essentially a point on the Elliptic curve, which can be described by its X/Y coordinates, or in a shorter for: X and one bit. How that is formatted into bits, then often text, depends on context. WebFor the secp256k1 curve, the private key is 256-bit integer (32 bytes) and the compressed public key is 257-bit integer (~ 33 bytes). ECDSA Sign. The ECDSA signing algorithm (RFC 6979) takes as input a message msg ****+ a private key privKey ****and produces as output a signature, which consists of pair of integers {r, s}.
