int | wc_curve25519_make_key (WC_RNG *rng, int keysize, curve25519_key *key) |
This function generates a Curve25519 key using the given random number generator, rng, of the size given (keysize), and stores it in the given curve25519_key structure. It should be called after the key structure has been initialized through wc_curve25519_init(). | |
int | wc_curve25519_shared_secret (curve25519_key *private_key, curve25519_key *public_key, byte *out, word32 *outlen) |
This function computes a shared secret key given a secret private key and a received public key. It stores the generated secret key in the buffer out and assigns the variable of the secret key to outlen. Only supports big endian. | |
int | wc_curve25519_shared_secret_ex (curve25519_key *private_key, curve25519_key *public_key, byte *out, word32 *outlen, int endian) |
This function computes a shared secret key given a secret private key and a received public key. It stores the generated secret key in the buffer out and assigns the variable of the secret key to outlen. Supports both big and little endian. | |
int | wc_curve25519_init (curve25519_key *key) |
This function initializes a Curve25519 key. It should be called before generating a key for the structure. | |
void | wc_curve25519_free (curve25519_key *key) |
This function frees a Curve25519 object. | |
int | wc_curve25519_import_private (const byte *priv, word32 privSz, curve25519_key *key) |
This function imports a curve25519 private key only. (Big endian). | |
int | wc_curve25519_import_private_ex (const byte *priv, word32 privSz, curve25519_key *key, int endian) |
curve25519 private key import only. (Big or Little endian). | |
int | wc_curve25519_import_private_raw (const byte *priv, word32 privSz, const byte *pub, word32 pubSz, curve25519_key *key) |
This function imports a public-private key pair into a curve25519_key structure. Big endian only. | |
int | wc_curve25519_import_private_raw_ex (const byte *priv, word32 privSz, const byte *pub, word32 pubSz, curve25519_key *key, int endian) |
This function imports a public-private key pair into a curve25519_key structure. Supports both big and little endian. | |
int | wc_curve25519_export_private_raw (curve25519_key *key, byte *out, word32 *outLen) |
This function exports a private key from a curve25519_key structure and stores it in the given out buffer. It also sets outLen to be the size of the exported key. Big Endian only. | |
int | wc_curve25519_export_private_raw_ex (curve25519_key *key, byte *out, word32 *outLen, int endian) |
This function exports a private key from a curve25519_key structure and stores it in the given out buffer. It also sets outLen to be the size of the exported key. Can specify whether it's big or little endian. | |
int | wc_curve25519_import_public (const byte *in, word32 inLen, curve25519_key *key) |
This function imports a public key from the given in buffer and stores it in the curve25519_key structure. | |
int | wc_curve25519_import_public_ex (const byte *in, word32 inLen, curve25519_key *key, int endian) |
This function imports a public key from the given in buffer and stores it in the curve25519_key structure. | |
int | wc_curve25519_check_public (const byte *pub, word32 pubSz, int endian) |
This function checks that a public key buffer holds a valid Curve25519 key value given the endian ordering. | |
int | wc_curve25519_export_public (curve25519_key *key, byte *out, word32 *outLen) |
This function exports a public key from the given key structure and stores the result in the out buffer. Big endian only. | |
int | wc_curve25519_export_public_ex (curve25519_key *key, byte *out, word32 *outLen, int endian) |
This function exports a public key from the given key structure and stores the result in the out buffer. Supports both big and little endian. | |
int | wc_curve25519_export_key_raw (curve25519_key *key, byte *priv, word32 *privSz, byte *pub, word32 *pubSz) |
Export Curve25519 key pair. Big endian only. | |
int | wc_curve25519_export_key_raw_ex (curve25519_key *key, byte *priv, word32 *privSz, byte *pub, word32 *pubSz, int endian) |
Export curve25519 key pair. Big or little endian. | |
int | wc_curve25519_size (curve25519_key *key) |
This function returns the key size of the given key structure. | |
