Encrypting with TDEA and a single key is pointless, because it is equivalent to encrypting with the original "single" DES, which is no longer considered strong enough to resist feasible attacks. In your own words (do not quote in any way from any source), briefly explain why decrypting with TDEA and a single key was a useful operation when TDEA was developed.
