I like crypto. Need I say more?

comment Is there any existing cipher capable of scaling from a 1 bit key up to a one-time-pad?
This doesn't really answer the question.

comment Problem in Entropy ?Please help me solve this
I'm voting to close this question as off-topic because it gives no explanation of what the OP has tried or where they are stuck. This is required as mentioned in the help center for these types of questions.

I marked this as a duplicate. If you feel that was incorrect, please update your question to state the difference in what you are asking vs what was asked/answered in the other question (and its answers).

Do you have any sources to back up your answer? I'm not so sure you are correct.

comment RSA: how does it work and how is it more secure than symmetric systems
You state in your question "how RSA is more secure than AES then". Sounds to me like you are asking for a comparison. If that is not your intent, I suggest you clarify the question.

comment RSA: how does it work and how is it more secure than symmetric systems
Comparing RSA to AES in terms of security is like comparing apples and oranges. They have very different benefits and use cases and are often used in conjunction, not as competitors.

comment how boolean functions can be converted into LSSS(LINEAR SECRET SHARING SCHEME)? Pls explain with example
Welcome to our site. In order for the site to be useful to you, you'll have to provide more context for your question. As is, it is impossible to tell what you are asking.

Could you provide more context for your questions?

comment Automated testing of cipher security for import/export compliance
Is your question something like this "given a set of formally specified regulations derived from law, can we verify that cryptographic cipher X (given it's mathematical representation or it's source code, or whatever, you should specify this), meets these regulations?"

comment If the ciphertext of Goldwasser-Micali has been falsified, what is the plaintext after decryption?
Are you interested in random bit flips or something more nefarious?
