Functions

int wc_ed448_make_public (ed448_key *key, unsigned char *pubKey, word32 pubKeySz)
 This function generates the Ed448 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_ed448_make_key (WC_RNG *rng, int keysize, ed448_key *key)
 This function generates a new Ed448 key and stores it in key. More...
 
int wc_ed448_sign_msg (const byte *in, word32 inlen, byte *out, word32 *outlen, ed448_key *key)
 This function signs a message using an ed448_key object to guarantee authenticity. More...
 
int wc_ed448ph_sign_hash (const byte *hash, word32 hashLen, byte *out, word32 *outLen, ed448_key *key, const byte *context, byte contextLen)
 This function signs a message digest using an ed448_key object to guarantee authenticity. The context is included as part of the data signed. The hash is the pre-hashed message before signature calculation. The hash algorithm used to create message digest must be SHAKE-256. More...
 
int wc_ed448ph_sign_msg (const byte *in, word32 inLen, byte *out, word32 *outLen, ed448_key *key, const byte *context, byte contextLen)
 This function signs a message using an ed448_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_ed448_verify_msg (const byte *sig, word32 siglen, const byte *msg, word32 msgLen, int *res, ed448_key *key, const byte *context, byte contextLen)
 This function verifies the Ed448 signature of a message to ensure authenticity. The context is included as part of the data verified. The answer is returned through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed448ph_verify_hash (const byte *sig, word32 siglen, const byte *hash, word32 hashlen, int *res, ed448_key *key, const byte *context, byte contextLen)
 This function verifies the Ed448 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 SHAKE-256. The answer is returned through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed448ph_verify_msg (const byte *sig, word32 siglen, const byte *msg, word32 msgLen, int *res, ed448_key *key, const byte *context, byte contextLen)
 This function verifies the Ed448 signature of a message to ensure authenticity. The context is included as part of the data verified. The message is pre-hashed before verification. The answer is returned through res, with 1 corresponding to a valid signature, and 0 corresponding to an invalid signature. More...
 
int wc_ed448_init (ed448_key *key)
 This function initializes an ed448_key object for future use with message verification. More...
 
void wc_ed448_free (ed448_key *key)
 This function frees an Ed448 object after it has been used. More...
 
int wc_ed448_import_public (const byte *in, word32 inLen, ed448_key *key)
 This function imports a public ed448_key pair from a buffer containing the public key. This function will handle both compressed and uncompressed keys. More...
 
int wc_ed448_import_private_only (const byte *priv, word32 privSz, ed448_key *key)
 This function imports an Ed448 private key only from a buffer. More...
 
int wc_ed448_import_private_key (const byte *priv, word32 privSz, const byte *pub, word32 pubSz, ed448_key *key)
 This function imports a public/private Ed448 key pair from a pair of buffers. This function will handle both compressed and uncompressed keys. More...
 
int wc_ed448_export_public (ed448_key *key, byte *out, word32 *outLen)
 This function exports the private key from an ed448_key structure. It stores the public key in the buffer out, and sets the bytes written to this buffer in outLen. More...
 
int wc_ed448_export_private_only (ed448_key *key, byte *out, word32 *outLen)
 This function exports only the private key from an ed448_key structure. It stores the private key in the buffer out, and sets the bytes written to this buffer in outLen. More...
 
int wc_ed448_export_private (ed448_key *key, byte *out, word32 *outLen)
 This function exports the key pair from an ed448_key structure. It stores the key pair in the buffer out, and sets the bytes written to this buffer in outLen. More...
 
int wc_ed448_export_key (ed448_key *key, byte *priv, word32 *privSz, byte *pub, word32 *pubSz)
 This function exports the private and public key separately from an ed448_key structure. It stores the private key in the buffer priv, and sets the bytes written to this buffer in privSz. It stores the public key in the buffer pub, and sets the bytes written to this buffer in pubSz. More...
 
int wc_ed448_check_key (ed448_key *key)
 This function checks the public key in ed448_key structure matches the private key. More...
 
int wc_ed448_size (ed448_key *key)
