Encryption

Hi All

Which one Encryption is best to use to encrypt data (large data)which is fast and secure? Give me some reference for this.


Thanks in advance

All depends on the type of data you wish to protect: The type of data will ultimately determine the complexity of encryption/decryption you wish to use.

Blowfish provides an adequate level of encryption/decryption and which can be found in the following link:

AES (Advanced Encryption Scheme) is a recent and very secure encryption scheme and I'm sure there are lots of fast implementations for it. Just do a search for it on Google.

AES (http://csrc.nist.gov/CryptoToolkit/aes/) is the encryption scheme used by the US goverment. Nobody managed to crack it so far.

Crypto++® Library 5.2.1 (http://www.eskimo.com/~weidai/cryptlib.html)

and the AES was written by belgian people at the university I studied :) :wave:
It was called Rijndael when it was developed and it was for a contest. Every participant could write their own encryption system and try to break the other systems. In the end Rijndael was chosen as the best one and became the new US goverment AES.

Don't be so sure. Security is a reactive process, you always come to know when it is breached. A secuirty system may be compromised, but unawared. Although its offtopic, but I heard a software company, that went out of business because there security system was compromised for 3 months and they come to know after that. The speciality of the software company was...err...."security systems".

I know myself that none reported so far that AES is breached but....thats the nature of security systems. Just my 2 cents ;)

True, every encryption can theoretical be hacked, however, AES hasn't been hacked as far as I know.
The only truly unbreakable encryption system is quantum encryption which can't be hacked because it would violate the laws of physics :wave: Anyway, this is way too off topic....
