<h1>PasteBox</h1>
|
||||
<p>It looks like yo don't have javascript enabled for this site. But thats ok. You can still submit and read the content of pastes by using a few curl/openssl/gunzip commands.</p>
|
||||
<h2>Get the paste</h2>
|
||||
<p>Lets say you have the following link <code>https://domain.tld/#/FeLq42kIQV69hQCJA8m9lg!5EDDziaCjceHjeG5UQ9M7-6wgyq5YVfysAEZ0wUNy6w</code>. Query the REST endpoint for the ID or part before the ! in the url hash.</p>
|
||||
<pre><code>$ curl -i https://domain.tld/api/FeLq42kIQV69hQCJA8m9lg</code></pre>
|
||||
<h2>Decrypt</h2>
|
||||
<p>Using Openssl you want to remove the header and pass the remaining base64 for decryption. The cypher used is aes-256-cbc. The key is the portion after the ! in the link.</p>
|
||||
<pre><code>... | sed '1,/^$/d' | openssl aes-256-cbc -d -a -k 5EDDziaCjceHjeG5UQ9M7-6wgyq5YVfysAEZ0wUNy6w</code></pre>
|
||||
<h2>Deflate</h2>
|
||||
<p>If as in the provided example the paste has been compressed pass it through gunzip. The header will have "zip: true" if it has been compressed.</p>
|
||||
<pre><code> ... | gzip -dc </code></pre>
|
||||
|
||||
<h2>Example Output</h2>
|
||||
<pre><code>$ curl -s "https://domain.tld/api/FeLq42kIQV69hQCJA8m9lg" | sed "1,/^$/d" | openssl aes-256-cbc -d -a -k 5EDDziaCjceHjeG5UQ9M7-6wgyq5YVfysAEZ0wUNy6w | gzip -dc
