Algorithms Used In Keygloo

In the late 1970s, an algorithm known as DES (Data Encryption standard) came into wide use for protecting financial, educational and other information. Later, during the 1990’s, this algorithm gave way to 3DES which is essentially DES carried over 3 times.

In the very recent past, even 3DES was felt to be too anachronistic and was retired. It was replaced by another algorithm called AES (Advanced Encryption Standard). All three are symmetric algorithm. AES can take key sizes of 128, 160, 192, 224 and 256 bits.

Keygloo uses AES – 256 bit to encrypt messages. You can read more on the AES algorithm by perusing the FIPS – 197(Federal Information Processing Standard) document available online.Around the same time, more specifically in 1977, three people, namely, Ron Rivest, Adi Shamir and Len Adleman came up with a public key encryption algorithm.

  

 

They called it RSA, fittingly. Public key algorithms, although useful for encrypting messages are seldom used for the purpose due to the complex resource feeding computations involved in the algorithm. However, they are a perfect fit for secure key exchanges.

The RSA algorithm can use keys of the order of 1024 bits to 4096 and even more if computing power so facilitates. However, even in the current times, 1024 bits is deemed adequate to protect information given the present computing power. So Keygloo uses 1024-bit RSA algorithm to encrypt the 256-bit AES key thus ensuring secure key exchange. Should computing power increase, Keygloo will keep up with the pace of advancing technology and increase its key size.
