About:

This library contains the following functions.

void create_ed25519_keyfile();
void remove_ed25519_keyfile();
String load_ed25519_keyfile();
String sign_ed25519_tx( String tx, const char* psk );
bool verify_ed25519_tx( String tx, uint8_t *pkk, uint8_t* signature );

create_ed25519_keyfile()

:: This function checks if a ed25519 key file exists on the device if not it creates one.

remove_ed25519_keyfile()

:: This function removes all key files on the device.

load_ed25519_keyfile()

:: This function opens the ed25519 file if it exists and returns the psk.

sign_ed25519_tx(String tx, const char* psk)

:: This function takes in a tx and the private key obtained with `load_ed25519_keyfile()` and creates a signature for it and also verifies.

verify_ed25519_tx( String tx, uint8_t *pkk, uint8_t* signature )

:: This function will take in your tx, private key from `load_ed25519_keyfile()` and signature from  `sign_ed25519_tx` functions and verify the signature matches the hash. This function is also used in sign_ed25519_tx as an extra measure.
