I'm looking at implementing a 64Bit AES symmetric encryption using the Security Builder API, though I'm having difficulty finding a working sample or piecing it together from the API reference.

Any ideas?

Hi,

I'm not sure what you mean by 64bit, AES is normally measured by key size, and the supported key sizes are 128,192 and 256 bits.

There's a good tutorial (showing SHA) here;

I think this code is really useful as it shows how to create the contexts and initialise the Security Builder code.

When doing AES, you generally,

create params

set key

begin

update * x

end

destroy the key

destroy the params
