Method Details

execute

public void execute(CryptoPathMapper.CiphertextDirectory ciphertextDirectory)
             throws IOException

Performs the backup operation for the given CryptoPathMapper.CiphertextDirectory object.

The directory id is written via an encrypting channel to the file CryptoPathMapper.CiphertextDirectory.path/"dirid.c9r".

Parameters:

ciphertextDirectory - The cipher dir object containing the dir id and the encrypted content root

Throws:

IOException - if an IOException is raised during the write operation

backupManually

public static void backupManually(org.cryptomator.cryptolib.api.Cryptor cryptor,
 CryptoPathMapper.CiphertextDirectory ciphertextDirectory)
                           throws IOException

Static method to explicitly back up the directory id for a specified ciphertext directory.

Parameters:

cryptor - The cryptor to be used

ciphertextDirectory - A CryptoPathMapper.CiphertextDirectory for which the dirId should be back up'd.

Throws:

IOException - when the dirId file already exists, or it cannot be written to.
