from ecc_dh.h:94

int uECC_make_key(uint8_t *p_public_key, uint8_t *p_private_key, uECC_Curve curve);

Implemented in ecc_dh.c:102

Arguments

Argument

Description

p_public_key

OUT -- Will be filled in with the public key. Must be at least 2 * the curve size (in bytes) long. For curve secp256r1, p_public_key must be 64 bytes long.

p_private_key

OUT -- Will be filled in with the private key. Must be as long as the curve order (for secp256r1, p_private_key must be 32 bytes long).

curve

Return value

returns TC_CRYPTO_SUCCESS (1) if the key pair was generated successfully returns TC_CRYPTO_FAIL (0) if error while generating key pair

Notes

side-channel countermeasure: algorithm strengthened against timing attack. @warning A cryptographically-secure PRNG function must be set (using uECC_set_rng()) before calling uECC_make_key().
