hi can someone tell me the difference as i see giganews has 256 bit encryption, but i am with newsdemon who offers 128bit encryption. will it still do the job and keep information transferred secure and private?

ok so 128bit encyption is good enough then for newsgroups?
if it isnt good enough you have bigger problems. either nobody is snooping on you and it does no matter or you are being spied on and that means bigger problems
I had to re-read on current cryptography to be able to respond to this post. Currently, the industry standard is 128 bit SSL. AES uses the Rijndael cipher which at >128 bit keys has been shown to be secure. For example, "The design and strength of all key lengths of the AES algorithm (i.e., 128, 192 and 256) are sufficient to protect classified information up to the SECRET level. TOP SECRET information will require use of either the 192 or 256 key lengths. The implementation of AES in products intended to protect national security systems and/or information must be reviewed and certified by NSA prior to their acquisition and use." — [4] (Quoted from http://en.wikipedia.org/wiki/Advance...ption_Standard.)
128 bit SSL would take 2^120 bit operations to compute all the possibilities to crack. I'm sure the NSA or other similar agency would find better use to devote their computer resources then one user downloading from usenet. :)

lol thanks for the info fletcher
No problem. Encryption is always a fun topic.Quote:
