Good catch too! These little details really help maintain a high level of security when dealing with keys.

<p>Please see the discussion here.  <a href="https://forum.cardano.org/t/cardano-cli-signing-a-transaction-without-directly-accessing-the-skey-file-in-plain-text/103742/11" rel="nofollow noreferrer">https://forum.cardano.org/t/cardano-cli-signing-a-transaction-without-directly-accessing-the-skey-file-in-plain-text/103742/11</a></p>
<p>cardano-cli should be able to read signing keys from a named pipe to maintain a high level of security while handling keys, a bug report was submitted but no further interactions.

<p>Thoughts? Alternative approaches? Maybe we can flag someone from IOG who can help clarify if this has been discussed and is a design choice or is it really a &quot;bug&quot;.</p>

If you want to formalise this for deeper consideration and discussion then a Cardano Improvement Proposal (CIP) could be raised at https://cips.cardano.org/
