add a stronger encryption for private internet access

i was wondering that if you guys can make a stronger encryption for private internet access like instead of having aes 256 bit can it go higher and have aes 512 bit as one of the features of private internet access.

    AES does not support a 512 bit key size (128, 192, 256)

    The only way to do this is cascading ciphers. Look at other cryptographic projects like Truecrypt to see how that works.

    You can do AES-256 twice for AES-256*2=512. But it would likely be safer to use different ciphers to add up to whatever strength you want. AES-256+BF-128+Serpent-128=512.

    It's fine to do cascades on storage media, but please don't do this for stream ciphers (data transfers).

    I agree that this is a bad idea. But people want sports cars with five hundred horsepower to drive through the school zones at fifteen miles per hour. Likewise people want crazy strong encryption.

    Cascading ciphers are not yet implemented. And they are not needed. So far no-one has ever managed to brute force a single solitary 128 bit AES or Blowfish cipher key. Not even once. And it is not really a concern to obsess about. It will never happen.

    If you think your data is in need of more security, use 256 bit AES and be happy. You absolutely do not need 512 bits of encryption.

    Here is an article I post on these forums every time this comes up.

    The short version is that your encryption is never going to break. Period.
