To customize key bindings, copy an existing key map and make your changes. Windows In the Start menu, select the DbVisualizer menu item. This opens either an Object View tab or an SQL Commander tab, depending on the object type: database object or script.

If you don't enter a required attribute or enter an attribute that is unsupported for a data type, you will get an error message when you click Execute to create the table. Information about the table's primary key columns, if any.

There are a lot of questions relating to license keys asked on Stack Overflow. But they don't answer this question. Can anyone provide a simple license key algorithm that is technology independent and doesn't required a diploma in mathematics to understand? The license key algorithm is similar to public key encryption. I just need something simple that can be implemented in any platform. Answers written as Pseudo code are perfect. So if a person presents a string, a complementary string can be generated that is the authorisation code. Below is a common scenario that it would be used for. Avoid asking multiple distinct questions at once. See the page for help clarifying this question. If this question can be reworded to fit the rules in the , please. There is no reliable licensing algorithm. A popular mechanism is to, at purchase, ask for the user's name, and then give him a license key that's derived from a cryptographic hash e. MD5 sum of the user's name, or some variation on it. Then, in the software you ask for their name again, plus the registration key that MD5-derived thing ; you check to see that they match, which activates the software. Can this be hacked? Once someone figures out how you're generating the license keys, they can generate their own. But don't worry so much about stopping the hackers from cracking your code. It's going to happen, but they're such a tiny part of the market that it won't significantly affect your overall sales. If your license key includes a digital signature, knowing how it's generated doesn't help the keygen writer in the slightest. They still need to break a digital signature algorithm - an achievement worthy of a scientific publication! In all honesty, what you're trying to do is pointless. Even if you encrypt the final executable. However, as a delaying measure or a way to decrease the chance of people getting premium support for stolen copies, it will help. Also for simple tracking of buyers. A lot of software uses name and possibly company string s and a hash function to generate a key. This has the advantage of being constant as long as the name is the same, the hash is, and so the key is. It is also a very simple system, especially if you use a well-known hash such as MD5. If you can get ahold of the processor name or speed, or anything else, you can run something like that. The only problem is system changes can render a code invalid, so you can either warn your users and give away part of the process or let them find out accidentally not good. One thing to consider is you don't need to be able to reverse the process. As long as you can replicate it with the same results any good hash function can , you can check the hashed results against each other and make sure it's valid. The more you put in, the more complicated it'll be, but the harder it'll be to crack. Hopefully that helps with your question. It's worth including a secret in the string that is to be hashed. Any attacker can simply MD5 their own name, adding a secret and using a more secure hash such as SHA-2 makes it MUCH harder. Of course, the secret needs to be included in the software, and can be extracted. XORing it with another string preferably that looks like it's a string used in the software will help disguise it. The best license keys are the ones digitally signed with an asymmetric encryption algorithm. You sign the key data with a private encryption key and embed the signature in the key, and the key validation which implies signature verification among other things is done with a public key. This way, no one can create license keys unless they have access to the private key which is... The problem is that there are very few and difficult algorithms which have sufficiently short signature sizes to be embedded in a product key. RSA is not one of them signature size for RSA512 is 1024 bits - too much. Most frameworks should have an HMAC-function for SHA1 or some other hash function. Worse case you could replace this with md5 key+id Don't take this algorithm too seriously, it's just an example and it can probably be broken very easily as the generation-key has to be included in the client, even though it's hidden in the binary somewhere. How may keys do you need to generate per second? For the user entering the key it's a one time or once per load event. Many key generation algorithms intentionally perform badly to thwart brute force attacks. However, that performance hit only normally becomes a bottle neck if you are... What's to stop your customer from distributing that key to others? Sure you could setup a license key server that records the number of activations but that costs money and what will happen if it goes down or goes away? In my professional opinion, create a software that is branded uniquely to a user encrypted inside the program of course. This way if they upload it to a pirate site of some kind, not only will other people know this guys personal information... I am able to take unique info out of the users technical environment that goes towards their key generation. So if anyone else intends to use it, the system does the check, halts and prompts for a valid key based on the new environment it is trying running in. Yes, you can hack the most sophisticated licensing systems ever created. Microsoft have tried and failed and they have the dosh to throw at it to. But this is really a barrier to casual piracy. If someone really really wants to hack it they will.. But this risk is fairly low considering what the software is for and the target market.

If there is a tooltip for the area, it will pop up in about a second. RSA is not one of them signature size for RSA512 is 1024 bits - too much. Most frameworks should have an HMAC-function for SHA1 or some other ring function. However, as a delaying measure or a way to decrease the chance of people getting premium support for stolen copies, it will help. The other folders group feature specific actions, such as actions to control the references graph, form editor, etc. What's to stop your sin from distributing that key to others. When you maximize a tab, the Navigation tabs are minimized to make as much room as possible available and the tab dbvisualizer pro license key string maximized fills all available space. This way if they upload it to a pirate site of some kind, not only will other print know this guys personal information.
