Function hacl_sys::Hacl_P256_ecdsa_sign_p256_sha2

pub unsafe extern "C" fn Hacl_P256_ecdsa_sign_p256_sha2(
    signature: *mut u8,
    msg_len: u32,
    msg: *mut u8,
    private_key: *mut u8,
    nonce: *mut u8
) -> bool

Create an ECDSA signature using SHA2-256.

The function returns true for successful creation of an ECDSA signature and false otherwise.

The outparam signature (R || S) points to 64 bytes of valid memory, i.e., uint8_t[64]. The argument msg points to msg_len bytes of valid memory, i.e., uint8_t[msg_len]. The arguments private_key and nonce point to 32 bytes of valid memory, i.e., uint8_t[32].

The function also checks whether private_key and nonce are valid: • 0 < private_key < the order of the curve • 0 < nonce < the order of the curve
