Functions

int wc_ed25519_make_public (ed25519_key *key, unsigned char *pubKey, word32 pubKeySz)
 This function generates the Ed25519 public key from the private key. It stores the public key in the buffer pubKey, and sets the bytes written to this buffer in pubKeySz. More...
 
int wc_ed25519_make_key (WC_RNG *rng, int keysize, ed25519_key *key)
 This function generates a new Ed25519 key and stores it in key. More...
 
int wc_ed25519_sign_msg (const byte *in, word32 inlen, byte *out, word32 *outlen, ed25519_key *key)
 This function signs a message using an ed25519_key object to guarantee authenticity. More...
 
int wc_ed25519ctx_sign_msg (const byte *in, word32 inlen, byte *out, word32 *outlen, ed25519_key *key, const byte *context, byte contextLen)
 This function signs a message using an ed25519_key object to guarantee authenticity. The context is part of the data signed. More...
 
int wc_ed25519ph_sign_hash (const byte *hash, word32 hashLen, byte *out, word32 *outLen, ed25519_key *key, const byte *context, byte contextLen)
 This function signs a message digest using an ed25519_key object to guarantee authenticity. The context is included as part of the data signed. The message is pre-hashed before signature calculation. The hash algorithm used to create message digest must be SHAKE-256. More...
 
int wc_ed25519ph_sign_msg (const byte *in, word32 inlen, byte *out, word32 *outlen, ed25519_key *key, const byte *context, byte contextLen)
 This function signs a message using an ed25519_key object to guarantee authenticity. The context is included as part of the data signed. The message is pre-hashed before signature calculation. More...
 
int wc_ed25519_verify_msg (const byte *sig, word32 siglen, const byte *msg, word32 msgLen, int *ret, ed25519_key *key)
 This function verifies the Ed25519 signature of a message to ensure authenticity. It returns the answer through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed25519ctx_verify_msg (const byte *sig, word32 siglen, const byte *msg, word32 msgLen, int *ret, ed25519_key *key, const byte *context, byte contextLen)
 This function verifies the Ed25519 signature of a message to ensure authenticity. The context is included as part of the data verified. It returns the answer through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed25519ph_verify_hash (const byte *sig, word32 siglen, const byte *hash, word32 hashLen, int *ret, ed25519_key *key, const byte *context, byte contextLen)
 This function verifies the Ed25519 signature of the digest of a message to ensure authenticity. The context is included as part of the data verified. The hash is the pre-hashed message before signature calculation. The hash algorithm used to create message digest must be SHA-512. The answer is returned through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed25519ph_verify_msg (const byte *sig, word32 siglen, const byte *msg, word32 msgLen, int *ret, ed25519_key *key, const byte *context, byte contextLen)
 This function verifies the Ed25519 signature of a message to ensure authenticity. The context is included as part of the data verified. The message is pre-hashed before verification. It returns the answer through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed25519_init (ed25519_key *key)
 This function initializes an ed25519_key object for future use with message verification. More...
 
void wc_ed25519_free (ed25519_key *key)
 This function frees an Ed25519 object after it has been used. More...
