RSA

Java implementation for RSA algorithm. Including: Encryption, Decryption, Mathematical attack and Chosen Ciphertext attack. Along with some graphs for Encryption time against Key size and Crack time for Mathematical attack against Key size.

For building most files a simple javac followed by java is sufficient. For graphs, linking to javafx is required.

Usage

RSA.java:

java RSA <message> <key size>

Example:

$ java RSA 123456 256

public  = 65537
private = 918350825889598730612884754855286080917835737783369769299975325737606264193
modulus = 54516266373484268123348395089629423809448476484967370282562576602408890372079
encrypted = 46353133933985245905238077722508135821614726273880596199400531980279236036366
decrypted = 123456

MathAttack.java:

java MathAttack <message> <key size>

Example:

$ java MathAttack 123456 32

public  = 65537
private = 1226056193
modulus = 1466595643
message = 123456
cracked = 123456
Success!

ChosenCipherTextAttack.java:

java ChosenCipherTextAttack <message> <key size>

Example:

$ java ChosenCipherTextAttack 123456 1024

public  = 65537
private = 18725573098282057244897358153609925053050495690862598717210115559334053351344819648420601502408121192262001478573674857473591526979794008658916281245684773816744056269983906210157316300544025352055843690934468591313777508110799963553777942491089970930306683239774692307635088881873551518602009366229193917309
