I like crypto. Need I say more?

comment How to compute 3P from elliptic curve where P is (28, 8)
Do you know how to add points? If so, $P+P+P=3P$

comment What are the advantages of Certificate Authority and Key Distribution Center over each other?
Can you explain what each means to you?

comment Small Prime Difference in RSA
@fgrieu, so the method I outlined is really no better than trial division, but fermat's method is. I hope you plan to write up an answer.

@fgrieu very interesting.

comment How Secure is a Pronounceable Password? In means of entropy
Do you have some pseudocode or anything on the method of generation? Once you know that, you can compute the entropy of the resulting passwords.

@Laura, I updated your question to hopefully make it more clear. I'll reopen. If I destroyed the original meaning of the question, please feel free to edit.

comment Small Prime Difference in RSA
The big benefit of this approach is that it works not just for a small $p-q$ difference, but also when $p-q$ might come from a small range of numbers (which could be fairly large themselves). For this specific question, starting at $\sqrt{n}$ is likely the better option, but I didn't want to steal your comment (which should be an answer) :)

comment Arranging Vigenere Cipher into columns
This question should be on StackOverflow as it is about programming and algorithms, not about cryptographic theory. I'll move it.

comment Implementation of garbled circuits using RSA
RSA typically isn't used for Yao's method. They define what they use for enc a little lower in the document

comment How do you test randomness?
Can you never prove pseudorandomness or do we just not know how? Existance of one-way functions would imply existence of pseudorandom generators right? It would also imply $P\neq NP$.

How many keys??
