A lot of people casually uses several technical terms. But not everyone is aware of the original meanings of such terms.
People tend to use these terms frequently, but, in several cases, they cannot provide any explanation for those terms. DES and AES are two such terms.
Key Takeaways
- AES is a more secure encryption algorithm than DES.
- AES has a larger key size and operates faster than DES.
- DES is an outdated encryption algorithm and should be used for something other than modern security applications.
Des vs Aes
DES is an older encryption standard that was developed in the 1970s. It uses a 56-bit key to encrypt data in blocks of 64 bits. AES is a newer encryption standard that was introduced in 2001. It uses a variable-length key (128-bit, 192-bit, or 256-bit) to encrypt data in blocks of 128 bits.
The term DES is the short format of the Data Encryption Standard. The word encryption standard is quite familiar among people, as many have at least heard about it.
People have a vague idea of these encryption standards. DES was created back in 1976 when computers were relatively new.
The term AES is the short format for Advanced Encryption Standard. The word encryption standard is quite familiar among people, as many have at least heard about it.
People have a vague idea of these encryption standards. AES was created in 1999, around the time computer was famous.
Comparison Table
| Parameters of Comparison | Des | Aes |
|---|---|---|
| Abbreviation | AES is the acronym for Advanced Encryption Standard. | The critical length of DES is 56 bits. |
| Creation | It was created in the year 1976. | It was created in the year 1999. |
| Key length | The key length of DES is 56 bits. | The key length is 128 bits, 192 bits, and 256 bits. |
| Security | It is not so secure and can be broken easily. | It is much more secure. |
| Encryption | It can encrypt up to 64 bits of just plain text. | It can encrypt up to 128 bits of just plain text. |
What is Des?
The term DES is used widely in the areas of encryption and technology—the word DES can be abbreviated into Data Encryption Standard.
As the name suggests, it is a type of data encryption that was in use. This type of DES was created in the year 1976.
It was when computers were just introduced. Also, access to a computer was limited to a few people.
The DES is relatively older than others.
The term DES has gone quite out of use in the recent past. People are aware of the encryption standards.
But they do not understand how exactly these standards work and the differences. As a person interested in tech, it is necessary to understand the fundamental differences that power the DES and the AES.
The DES is much older, so the technicalities of that are low compared to our times.
The critical length of the Data Encryption Standard is just 56 bits. It can encrypt up to 64 bits of plain text as the input. Under the DES, a block is encrypted with data in the size of 64 bits per block.
It is also not so secure and can be broken without any struggle. DES is much slower than the new standards, and was designed by the prominent tech corporation IBM.
What is Aes?
The term AES is used widely in the areas of encryption and technology. AES can be abbreviated as Advanced Encryption Standard.
As the name suggests, it is a type of data encryption.
AES was created in the year 1999. It was when computers were popular worldwide and accessible to everyone.
The AES is relatively newer than the DES.
The term AES remains a vital part of the encryption standards today. People are aware of the encryption standards.
But they do not understand how exactly these standards work and the differences. As a person interested in tech, it is necessary to understand the fundamental differences that power the DES and the AES.
The AES is much newer,, so the technicalities are relatively better than the DES.
The critical length of the Advanced Encryption Standard can be 128 bits, 192 bits, or 256 bits. It can encrypt up to 128 bits of plain text as the input.
Under the AES, a block is encrypted with data in the size of 128 bits per block. It is pretty secure and cannot be broken easily.
AES is much faster than the previous standards. Vincent Rijmen and Joan Daemen designed it.
Main Differences Between Des and Aes
- The abbreviation of the word DES is Data Encryption Standard. The abbreviation of the word AES is Advanced Encryption Standard.
- The DES was created in 1976 when the computer was unavailable or accessible to everyone. The AES DES was created in 1999 when computers were famous and accessible.
- The security of this old DES system is poor and can be broken. The AES is far more secure and cannot be broken easily.
- The DES was designed by the prominent company IBM. The AES was designed by two people, Vincent Rijmen and Joan Daemen.
- The old DES is slow with the process. The AES is relatively faster with the process.
I’ve put so much effort writing this blog post to provide value to you. It’ll be very helpful for me, if you consider sharing it on social media or with your friends/family. SHARING IS ♥️
The comparison table is extremely helpful in understanding the key differences between DES and AES. The details regarding key length, security, and encryption process are well presented and easy to comprehend.
The article clearly emphasizes the importance of understanding the differences between DES and AES in the context of encryption. The historical and technical aspects are effectively explained, making it easier to appreciate the significance of AES over DES.
I believe the article offers a great starting point for anyone seeking to delve into encryption standards. By highlighting the outdated nature of DES and the superior features of AES, it reflects the evolution of technology in the realm of encryption.
The content feels slightly repetitive, especially in the ‘What is Des?’ and ‘What is Aes?’ sections. It might benefit from condensing the information into a more concise format while maintaining clarity and depth.
The article serves as a beneficial source of knowledge regarding encryption standards. However, the brief historical overview of DES and AES could be enriched with additional factual context to further enhance its educational value.
Although the article does well in explaining the differences, it lacks a broader perspective on the future of encryption standards. It would have been interesting to explore potential advancements or upcoming trends in this field.
The article provides a very informative and detailed explanation of the differences between DES and AES encryption algorithms. It helps better understand their characteristics and benefits. Very well written!
I strongly agree! This article is very insightful and contains useful knowledge for those interested in encryption. They provided a comprehensive comparison of DES and AES, leaving no room for questions.
