Problem 44961. RSA decryption
Decrypt a large integer string using RSA decryption given the public key (n) and private key (d). Convert the large integer decryption into an output message string with UTF-8 representation.
Example:
encrypted_message = '158037161019988039882393476857386648994978438821991287680442802412825849535544067751541256843540494019';%input n='418336393847020647250825879743341651032293545176800777981294580200903315345456262337972725306797613061';%input d='8444986024072025211908427894173383040354675378319105204646840203847580180874615752845913488969020869';%input decrypted_message = 'I like to swim!';%output

David -- Good problem. I got sidetracked by the fact that the arguments 'd' and 'n' in the solution template are reversed from the order that they are provided in the test problems.
Sorry, I did not mean to do that. Fixed.
Similar to the first https://www.mathworks.com/matlabcentral/cody/problems/44959-rsa-encryption-using-public-key It is necessary to convert the number obtained back from base 256 to base 10.
