RSA Calculator

Instructions

• If c = the coded item;  m = your secret key;  and n,r = the public key;  enter c ^ m MOD r and press the "=" key.
• NOTE: If the encoded number is 000, the decoded number will be r. No need to use the calculator.
• Always press the "CLEAR" key after decoding a number and before moving to the next number in the sequence.
• NOTE: If the encoded number has a left zero, do not enter the zero. If the result is a two digit number, add a left zero.
• Separate the decoded string of numbers into two digit segments.
• To convert a two digit ASCII code to a letter press the "Num -> Letter" key
• Record the result.
• Always press the "CLEAR" key after converting a number and before moving to the next two digit segment.
• Continue this process to convert the number string into a readable message.
