comment Speed up modular exponentation with fixed base and modulus
I want to know this "How big is the gain and what resources are needed?" The explanation in the blog is too big for fast understanding.

comment Timing attack on modular exponentiation
I would like to see an answer how the knowledge of 1 bits would speed up breaking the modular exponentation.

comment What operations are used in symmetric cryptography and why?
@Reid dude, I know what they do. I asked what's the difference for using them in cryptographic algorithms. Why is + mod 32 used in MDx?

Reid, so can you try to explain the choise of operations in protocols you mentioned?

@Thomas ok, + doesn't invert itself, but it can be inverted with -. So what's the difference?

Both xor and addition with overflow are involutions, what's the difference?

comment Is triple des similiar to RSA in that they message size is limited to the key size?
@poncho lol block cipher must not be symmetric, should it?

One AES opeation can encrypt only one block, for every thing else you need modes of operations.

comment Which version(s) of SRP are in ISO/IEC 11770-4:2006?
If you consider you local network secure, you can use plain text :)

There is already TSL-SRP, what's the difference between it and ISO?
