The tool uses automatic on-the-fly encryption with AES 256
bit key length.
This table includes speed measurements for common algorithms, such as AES with a 256
bit key in output feedback mode (OFB) (see [19]), the RC4 stream cipher (see [8]), and the Salsa20 (see [20]) stream cipher and the HC128 stream cipher (see [21]), together with our proposal.
The cipher takes 128
bit key and 128 bit initialization vector (IV).
Each uses a standard 128
bit key. In the export version, this key is not reduced in length.
A 56
bit key creates 72 quadrillion possible combinations.
In addition to those elements, the keyed rounds use 32
bit key multiplication, data-dependent rotations, and key addition.
"Forty
bit key technology is adequate to stop someone from nicking US$50 off your bank account but not for protecting industrial secrets and medical records," says Whitfield Diffie, a widely respected expert on cryptography and an engineer at Sun Microsystems.
