    <p>I have a PHP application that has passwords stored in the database as the output of sha1($password), which is apparently the hex representation of the binary SHA1 hash. (as I understand it)</p> <p>I would like to convert that to a format that is compatible for Apache .htpassword files, which needs to be the base64 encoded binary value or the output of base64_encode(sha1($password, true)).</p> <p>I found this thread: <a href="https://stackoverflow.com/questions/2914504/convert-base64d-sha1-hashes-to-hex-hashes">Convert base64&#39;d SHA1 hashes to Hex hashes</a> ... which is doing the opposite of what I need to do, and it works great. I tried to change the ordering of the commands and use hex2bin instead of bin2hex, but that doesn't work:</p> <p>Fatal error: Call to undefined function hex2bin() in php shell code on line 1</p> <p>Apparently that is not available until PHP 5.4, and this server is still on 5.3.x <a href="http://php.net/manual/en/function.hex2bin.php" rel="nofollow noreferrer">http://php.net/manual/en/function.hex2bin.php</a></p> <p>Here is the <em>real</em> problem. I <em>actually</em> need it to convert in PERL, preferably only using <em>standard</em> built-in modules to keep everything simple. I am not sure why they are using perl for this step, but I am trying to edit one very small part of a larger application and don't want to change the whole thing yet :)</p> <p>To be clear, I am <strong>not</strong> trying to convert hex numbers to binary numbers. This is a hex representation of a binary value, stored in a perl "string" :)</p> <p>Thanks in advance, Tommy</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
