Am I Doing RSA Correctly?

I am trying to figure out how to complete RSA manually. I am trying to encode a simple block message (Mi). I used CrypTool to determine the encryption. When I "manually" computed the plaintext, I obtained a different number than what CrypTool provided. Can someone guide me? Am I doing the manual encryption for RSA correct?

• What is the integer $A$? Jun 16 at 15:03
• It could be also $Z$... Jun 16 at 15:09
• there are many textbook RSA example on internet, please refer to them. your Z is called ${\phi(n)}$ . and public exponent e is chosen as ${1<e<\phi(n)}$, and private exponent d is selected such that ${ed \equiv 1(mod(\phi(n))}$

• Just used the Cryptool Online RSA with your setup and got the $\color{red}{Red}$ numbers. What is your problem, then? Jun 16 at 18:20
• @kelalaka Thank you for the online resource! When I used CrypTool RSA Encryption and input the text MI, I receive the following: Numbers input in base 10 format: 360 / Encryption into ciphertext: 11,807. Why is there only one number?
