PSA_ECC_FAMILY_SECP_K1 macro
SEC Koblitz curves over prime fields. This family comprises the following curves: secp192k1, secp224k1, secp256k1. They are defined in _Standards for Efficient Cryptography_, _SEC 2: Recommended Elliptic Curve Domain Parameters_. https://www.secg.org/sec2-v2.pdf
Syntax
#define PSA_ECC_FAMILY_SECP_K1 ((psa_ecc_family_t) 0x17)
Notes
For secp224k1, the bit-size is 225 (size of a private value). Mbed TLS only supports secp192k1 and secp256k1.
