public static boolean isIdentityFilePresent(Path path)

Returns true if the identity file path exists. Otherwise false is returned.

Parameters:

path - path to identity file

Returns:

true if file exists

readIdentityFile

public static Identity readIdentityFile(Path path)
                                 throws IOException

Reads the identity from code. Throws IOException if file cannot be read or file has unexpected content.

Parameters:

path - path to identity file

Returns:

The identity contained in the file

Throws:

IOException - if identity could not be read from file or has an invalid proof of work

writeIdentityFile

public static void writeIdentityFile(Path path,
                                     Identity identity)
                              throws IOException

Writes the identity identity to the file path. Attention: If path already contains an identity, it will be overwritten without warning.

Parameters:

path - path where the identity should be written to

identity - this identity is written to the file

Throws:

IOException - if the identity could not be written to the file

deleteIdentityFile

public static void deleteIdentityFile(Path path)
                               throws IOException

Deletes the identity file specified in the configuration.

ATTENTION: Messages directed to the present identity can then no longer be decrypted and read. This step is irreversible. Should only be used if the present identity should never be used again!

Throws:

IOException - if identity file could not be deleted
