prime256v1
prime256v1 is an elliptic curve used in public-key cryptography. It is the OpenSSL name for the NIST/SECG standardized curve known as P-256 or secp256r1. The curve is defined over a 256-bit prime field and provides about 128-bit security for ECDSA and ECDH, making it a common choice for digital signatures and key exchange in TLS and X.509 certificates.
The curve is a short Weierstrass form over the prime field F_p with the following domain parameters:
Naming and standardization: prime256v1 is widely recognized as P-256 by NIST and secp256r1 by SECG. It is
