Body
<p>Here is an algorithm in Java:</p> <pre><code>public String getHash(String password, String salt) throws Exception { String input = password + salt; MessageDigest md = MessageDigest.getInstance(SHA-512); byte[] out = md.digest(input.getBytes()); return HexEncoder.toHex(out); } </code></pre> <p>Assume the salt is known. I want to know the time to brute force for when the password is a dictionary word and also when it is not a dictionary word.</p>

1. COCould be a minute or a week. Depends on the password, the salt, the machine that is used to brute-force and the algorithm implementation.

2. COMuch more heavily optimised algorithms are used for brute-forcing. And more and more GPUs.

Guidance

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.
