Aes

Advanced Encryption Standard (AES) is a cryptographic block cipher algorithm.

Des

Data Encryption Standard (DES) is a cryptographic block cipher algorithm.



Faster slower current

Example

"Personally i would recommend using aes as its very easy to implement and with its being sensitive personal data would provide enough encryption to keep people out unlike something like des"

from question  

What is the most appropriate encryption for a small to medium companys' MSSQL database

"Aes is the current preferred symmetric encryption algorithm;des is not longer recommended for new work and has some known weak keys"

from question  

Encrypt 8 byte string / base64 encode / max length 20 bytes

"This shows that the timings are sensitive to buffering and that aes is faster than des"

from question  

Copying bytes from FileInputStream to CipherOutputStream (or vice versa) extremely slow

"Using des assuming it s a little faster than aes and requires a smaller key and"

from question  

Avoiding line breaks in encrypted and encoded URL string

"If aes is negotiated it s faster than des and 3des used by default by older applications"

from question  

Using pscp.exe for sftp transfer is very slow compared to filezilla

"Aes can be even much faster than des or 3des when the cpu supports aes-ni"

from question  

Fast, simple to use symmetric cipher for integer encryption in Java

"Des turned out to be even slower than aes but for my current requirements a much simpler algorythm rc4 is sufficient"

from question  

Speed up android DES encryption/decryption

"Des is usually substantially slower than aes on modern hardware and has keys that are far too short for modern use"

from question  

How to encrypt video from url and save encrypted video to device's SD Card

"Aes will indeed yield a considerably faster result than des"

from question  

Advise on file encryption performance in Java

Secure use aes

Example

"But don t use des it is not secure use aes it is no more difficult to use and is secure"

from question  

Encryption and Decryption in Text Files Java

"Des is not considered secure anymore you should always avoid using it;aes is still considered safe you could use 256 bits keys"

from question  

Strongest cipher available to use with C/C++?

"Des is extremely easy to crack nowadays;please use aes or at least 3des if aes is not available"

from question  

DES encryption and cipher modes

"And no des is not secure and in fact has been in brute-force range for at least a decade depending on attacker capabilities;it has been deprecated since about 1999 in favor first of triple-des formally tdea and then aes and was officially withdrawn about 2005 as i recall"

from question  

Java Decryption - Input length must be multiple of 8 when decrypting with padded cipher

"Use aes - using des isn t any easier than aes"

from question  

Java - Decryption : javax.crypto.BadPaddingException

"To start with aes rijndael is definitely recommended in favor of des as the encryption algorithm;des is not considered secure enough any longer"

from question  

String encryption PHP/Java

"Also see why aes is more secure than des"

from question  

Which encryption AES/DES should i use for private key for ssl certificate?

"Sorry - triple des is no longer considered best practices;aes is simply a better algorithm so if you can use it then you should"

from question  

Which is the best encryption mechanism, Triple DES or RC4?

"I ve read that aes encryption is more secure than the triple des encryption ms is using in their example above"

from question  

VB.NET Encryption using a password

Size known theoretical

Example

"According to this analysis aes rijndael-128 is more than twice as fast as des 3des with a bigger key size more secure"

from question  

Fast, simple to use symmetric cipher for integer encryption in Java

"Note that the effective key size of aes is larger than triple des"

from question  

Triple DES encryption on C# and PHP yields different results

"Triple des is generally better but there are some known theoretical attacks;if you have a choice of cipher you might want to look at aes instead"

from question  

DES Encryption

Others

Example

Edit 3des is better than des in the sense that it s significantly more secure but still less secure than aes but it performance is of necessity significantly worse than aes des or twofish because you re essentially applying des three times

from question  

DES encrypt but Fortify report Weak Encryption on PHP 5.5.22

Which steps of aes encryption makes it less vulnerable than des

from question  

Why is AES more secure than DES?

Turns out this was a hardware failure the aes commands need more power than the des crypto1 ones 50 more which the antenna failed to deliver at the reading range i was testing with

from question  

DESfire EV1 AES authentication no reply

Though it s unrelated to your actual question des is generally slower than aes at least in software so unless you really need to keep the key small aes is almost certainly a better choice

from question  

Avoiding line breaks in encrypted and encoded URL string

If you used aes then you might see a better speedup over the des 3des observations

from question  

Hyper-threading Performance Comparison

Ek3 dk2 ek1 plaintext that is the definition of triple des 3des not des that is encrypt plaintext with des as with key 1 decrypt that result with key 2 encrypt that result with key 3 3des or triple des encrypts three time with des;so aes would be ek plaintext with aes
