If you received a message from someone that was encrypted with this script, you can decrypt it with your ssh private key using the following command without installing anything:<br>
|
|
<code>bash <(curl -s https://sshenc.sh/sshenc.sh) -s ~/.ssh/id_rsa < file-containing-the-encrypted-text.txt</code>

<h3>Run it from remote every time</h3>
|
|
If you are
|
|
<ul>
|
|
<li>really brave, and</li>
|
|
<li>want to be sure to run the latest version every time, or</li>
|
|
<li>maybe don't want/can't install files</li>
|
|
</ul>
|
|
you can use an alias that downloads and executes the script every time:<br>
|
|
<code>alias sshenc.sh='bash <(curl -s https://sshenc.sh/sshenc.sh)'</code>
|
|
<br>
|
|
<br>
|
|
To add it to your environment permanently:<br>
|
|
<code>echo "alias sshenc.sh='bash <(curl -s https://sshenc.sh/sshenc.sh)'" >> ~/.bashrc</code>
