What are the difference between DES and RSA algorithm?

DES is a symmetric cryptographic algorithm, while RSA is an asymmetric (or public key) cryptographic algorithm. Encryption and decryption is done with a single key in DES, while you use separate keys (public and private keys) in RSA. DES uses 56-bit keys for encryption while RSA uses 2600-bits of KEY


What is Difference between DES and RSA algorithm?

1. RSA comes under Asymmetric and DES comes under Symmetric 2. RSA is more secure than DES.


Why the DES is slower in software?

I can only guess that you ask about the performance of the DES algorithm when implemented in software as opposed to hardware. Any algorithm that can be economically implemented in hardware will perform faster in hardware than software by orders of magnitude in the general case. Encryption algorithms such as DES are often based on a shift-combine-shift sequence, which is fairly easy to implement in hardware, but can take considerable processing time when implemented in software.

Why 48 bit key is USED in des algorithm?

The total key length for single DES is 56 bits. At the time, it was felt that was adequate so that someone could not easily guess what the key was. With automated approaches that has been shown to be too weak for good cryptoanalysis.

Which is better encryption algorithm among DES Blowfish and MD5?

MD5 isn't a encryption algorithm, it's a hashing algorithm. Encryption will 'hide' the meaning of the encrypted text, while MD5 will 'add up' all the text to come up with a number. This number can be compared to another time this file was 'added up', to provide a simple kind of check to see if the text has been changed or if it is the same.


What is the DES algorithm And what are its variants?

The original DES algorithm, I believe, did only two things bit shifting and bit substituion. It di these operations repeadtley and on a very nonlinear fashion. I guess kinda like putting scrabble letters in a bag and shaking them up. There are a couple variants I know of. Lucifer, which was developed by IBM in the 70s. And then there is Enigma.
