Discuss the value of cryptography methodology and the various uses to ensure the integrity of data.

Cryptography is incredibly valuable because it allows for us to take data and hide it while it is moving from one place to another. The value is that it is scrambled or moved around and then sent to its destination where it can then be turned back into its original message. The point of this is to help prevent attackers from stealing data from the network while it is in transit. The main types of encryptions are symmetric, asymmetric, and data hashing. The differences are that symmetric will use the same key that was used to encrypt the message to decrypt it. Asymmetric encryption will require two different keys to decrypt the data. Hashing is where a piece of data is put through an algorithm and is then sent to its destination.

Hello Jacob,

I briefly read about hashing and was a little confused on the process. I think in your explanation you did a great job of simplifying the method of hashing. Asides from the key another difference in symmetric and asymmetric is asymmetric provides two types of permutations where as symmetric only provides 1.

Cryptography Methodologies are essential to every company using Internet accessible devices. There are several different types of methodologies used in cryptography. Each type of encryption should be used for specific scenarios. Some of the most common types of encryptions are asymmetric encryption, symmetric encryption, Data encryption standard and advanced encryption standard. These encryptions alongside algorithm’s facilitate the protection of our data. When trying to encrypt large bulks of data or protecting payment information in the form of credit cards, companies typically use symmetrical encryptions. Symmetric encryption allows the system to move faster than asymmetric when trying to process information at higher speeds. Symmetric encryption allows safety of the data using a one key encryption. Symmetric encryption requires the same key used to encrypt the message also be used to decrypt the message. The message is sent using permutations. Using the same key for encrypting and decrypting can cause potential security risk as explained in article from Key Factor “people (or technology) who want to correspond via symmetric encryption must share the key to do so, and if the channel used to share the key gets compromised, so does the entire system for sharing secure messages since anyone with the key can encrypt or decrypt those communications.” When to use symmetric encryption vs. asymmetric encryption (2023) When security is a top priority and time constraints are not as huge of an issue asymmetric encryption is used. Asymmetric encryption provides more security than symmetric. With asymmetric encryption two distinct types of permutations are used whereas with symmetrical encryption only one type of permutation is used. Asymmetric encryption is used for things like digital signatures, block chains, and public key infrastructures.

Hi Latoya, you have a TON of great information here. I also mentioned the symmetric encryption because I believe it is one of the most important ones we could have mentioned here. I like how you mentioned so much detail over the symmetric encryption as well.

[Amy Hastings]

Cryptography is very useful and also very important because it helps protect your data secretly by using special keys. It is also only accessible to people who are given the authorization to access this information. This is good because it ensures the safety of the data in things like emails and others. The various uses would be the symmetric cryptography meaning it is shared by the encryption as well as the decryption and that lets the data move between different platforms safely. Another is the asymmetric cryptography because this one is for the public and the private use but only those authorized can get into the private one while everyone else can only use the public one letting them communicate between each other but in a safe manner.

[Jacob Mannon]

Amy,

I think you did a good job explaining cryptographic keys. I like your example of emails. It seems that phishing and email scams are so common now that having encrypted emails is almost a must. Everyone has to protect their data and web usage, so encryption is an excellent tool to have.

Cryptography is crucial for securing data and ensuring its integrity by transforming readable data into an unreadable format using encryption algorithms. This process protects information from unauthorized access and tampering, ensuring that only authorized parties can access and modify the data. Key cryptographic methods include encryption, which secures data both at rest and in transit, which generate unique hash values to verify data integrity; digital signatures, which authenticate the sender and confirm that the data has not been altered; and key management, which involves the secure generation, distribution, and storage of cryptographic keys. These techniques collectively safeguard sensitive information, maintain data integrity, and build trust in digital communications and transactions.

Hello Braden,
After reading your discussion post, I thought you did a great job explaining what cryptography is and how it’s being used to secure data. I also liked how you chose to talk about the encryption side of cryptography because it’s a great way for people to secure their data from hackers.

[Jason Springer]

Cryptography is a method used to protect data by converting it into a secret form so that only authorized users can access or understand it. This method is valuable because it ensures the integrity, confidentiality, and authenticity of information, which are crucial in today’s digital world. By using cryptography, sensitive data—such as passwords, bank transactions, and private communications—can be kept secure from unauthorized access and tampering. One key application is in verifying the integrity of data. Digital signatures, for example, help ensure that the information hasn’t been altered during transmission. If someone tries to change the data, the digital signature will no longer match, indicating a potential security breach. Overall, cryptography plays a critical role in protecting personal and organizational data from cyberattacks, ensuring that sensitive information remains private and trustworthy. It builds trust in digital systems, making it essential for online activities like banking, shopping, and communications.
