Why RSA Decryption process takes longer time than the Encryption process?

Question

I have some idea that it is due to some complex calculation, but i want to know about what exactly happens which takes long time than the corresponding encryption process. Any l

Answer 1

The encryption power is usually chosen to be a prime of the form 2^n+1 (17, 63357) which requires a relatively few multiplication operations. The decryption value will be a much larger number as a consequence, and thus take more work to compute.
