Bad cryptography means the presence of a weak security system (encryption), which puts the data at risk. This type of encryption makes it possible for a third party to intercept the data without the required decryption key.
The length of a 40-bit key has been debated to be too short according to current standards. The keys were common in the software released before 1999. In 2004, the computers could take a little under two weeks for someone to crack and guess the key. The pace of searching for a 40-bit key has drastically increased. With current systems, an extensive corporate network would be able to do the same work in a couple of seconds. This fete is practical due to the availability of many computers in the system which share the burden.
The Wired Equivalent Privacy (WEP) was an algorithm that ensures the safety of the data on wireless networks. It uses the 40-bit key for encryption of the data. It was discovered that with some new software present in current computers, it became easier to crack the WEP. In order to curb this, the Wi-Fi protected Access (WPA) was implemented. It was implemented in 2003 and could produce and operate a 256-key bit to operate. The current standard is an improvement of the WPA. It is referred to as the WPA2, and it uses an encryption key that encrypts the network with a 256-key.
When looking for an excellent cryptographic key, the length is an important factor. This reasoning is justified because a longer cryptographic key is safer than shorter ones. A longer cryptographic key will require the user to enter a specific key since the length of the key ensures that the key is increasingly random. The more the cryptographic key is random, the harder it becomes for a person to guess the code accurately.
According to Garfinkel, the 128-bit key is the best key to use in the production of cryptographic keys. This key size is considered to be out of reach for conventional digital computing techniques and is expected to remain this way for the foreseeable future. This fact is justifiable since, as one continues to input the 128-keys, it becomes harder and harder to track the number of operations. With this being the case, many hackers will find it very hard to break this key.
When choosing cryptosystems, we need to be very careful. The safety of the data which will pass in the hands of these cryptosystems makes this need for care very urgent. Had there been a single cryptographic suite which was responsible for all the functions performed in the current cryptographic suites, all hell would break loose. This havoc will ensue because one only has to break into this single system, and all the data will be at their disposal. A higher risk will be posed once this singular cryptosystem is put in place as compared to the numerous ones we currently have.
As cryptographic keys are becoming harder and harder to break, the hackers are also using more cunning ways to crack the codes. The regular update and checks for any new threats should be done as regularly as possible to reduce this. The length of the cryptographic keys makes the private keys very important. However, these private keys often get lost in the public key cryptography system. The loss of these keys causes unrest because the keys may fall in the hands of the wrong people.
