Error message

This method is not implemented yet

What it means

Error "This method is not implemented yet" thrown in trekhleb/javascript-algorithms.

  throw new Error('This method is not implemented yet');
};

Solutions

  1. Do not call hillCipherDecrypt; it is a placeholder that always throws.
  2. Implement Hill cipher decryption (inverse key matrix modulo 26) before using this function.
  3. Catch the error and route to a supported decryption routine if decryption is required.

When it happens

Trigger: hillCipherDecrypt is invoked at all — the exported function is an unimplemented @TODO stub whose body unconditionally throws.

Common situations: Attempting to decrypt Hill cipher ciphertext with this module before hillCipherDecrypt has been implemented (marked with a @TODO).
