I am not going to lie, this is for a class project but I am lost and can't figure out where things are going wrong. We were tasked with coding an RSA algorithim based off a lab we previously did in class. The lab and project description can be found …

Microsoft first started warning people that the there was going to be an important change to Windows' certificate requirements back in June. A change that is designed to improve security across the Windows platform by way of increasing the RSA key length to a minimum of 1024 bits for certificates …

hello,I Need RSA system code with javascript ,i heared there're some rsa libraries in the internet , i looked for it , and i found some thing but it's not what i look for , i look for library applied (PKCS #1 v2.1) or (PKCS 12 v1.0),i have project and …

So I'm trying to write this program in C that will take a message the user types in and encrypt it using an RSA public key that the user supplies. I know there are encryption functions and libraries in C but I want to actually recreate the algorithm in code …

I am implementing RSA in C++ and here's my design(code structure). *keygen.h* namespace rsa{ class keygen{ public: //Constructor keygen(size); //Generate keys void generate(); //Getters string gete(){ return xyz; } .. .. .. private: //initializes bignums void initall(); keygen(){} //Private Member variables goes here } } *prime.h* namespace rsa{ //First 100 …

I have been programming in C++ for a while now. I heard about RSA Encryption algorithm, and i have read many online sites on how it works. But i still cant grasp how the algorithm works. i have tried to make programs with RSA, but they doesnt encrypt. If you …

Hi trying to recover an RSA encrypted 5 character word using a forward search dictionary attack in Python but having difficulty. The word was encrypted in 2 24 bit blocks (3648141 5604637) padding last block with a space e = 5 n = 21508387 table = {} for ptext in …

I am working for encryption and decryption using rsa algorithm ,and adding my own concept in rsa, after rsa and padding i m getting a string like- 100011234A12300A12A231A234A981A for different input output string is increase... Is there any technique by use of that i can compact this string [ then …

Hi I have a problem with RSA encryption/decription of txt files, I have one method to create a pair of RSA keys and save them into a file, then i made two methods, one for encryt and one for decrypt, encrypt method works fine, but when I want to decrypt …

Hi, I need to find p,q and e values for RSA. Here is a simple & short description of RSA. [QUOTE]Your enter a word (actually it is a sentence but for now a word) then program will convert letters to numbers (like a=1 m=13 etc.) and group them. Use with …

Some might argue that it has been a bad year for encryption. After all, just as the last decade was ending came reports that the algorithm that is used to encrypt GSM mobile phone calls (as used by some 4 billion people around the world) had been cracked wide open. …

How would one calculate the number of bytes of plaintext that could be encrypted as a single block given the key size? And how could you then calculate the number of bytes of cipher text that can be decrypted in a single block given the same key size because I …
