I like crypto. Need I say more?

This question appears to be off-topic because it is looking for software recommendations.

They are different but related somewhat.

I'm going to close as unclear until you can add more detail. See Poncho's comment for specifically what you should add.

comment Is the Vigenère Cryptosystem malleable?
What research have you done? Also, can you give your (mathematical) description of vigenere?

comment How is security of server's RSA private key is ensured?
How and where the private key is stored depends on how you configured the system. Additionally, each service may have it's own preferred place to store a private key. This question should be on our sister site Security.SE. Our site deals with more theoretical aspects of crypto. That site deals with more practical aspects. I'll migrate it.

I've moved your question to Security.SE as it will be a better location for this question.

comment Maturity of searchable encryption schemes
What research have you done? I would consider this a "basic level" question which the help center as this to say about: "However, please provide an indication of what you are not understanding/need clarification on and your attempts at solving it, so we have a clear indication of where you are stuck."

comment Cracking RSA with Small exponent 5
n is 1024 bits. If n was generated properly, you won't be factoring it any time soon.

comment Cracking plain RSA by factoring the modulus n
Since we don't really do code review here or help debug, I haven't looked at your code really. I can give a suggestion, however. Take a look at this answer on a previous question.

With how small the parameters are, just use brute force.

comment Decrypt with only the cipher file and the key?
Hmm, based on the information you've given us, try every cipher/mode combination known to man (from the most probable to the least). Also known as, brute-force.

List questions are often closed as off-topic here. There have been some exceptions. I'll let the community decide on this one.
