The Public and Private Key pair comprise of two uniquely related cryptographic keys. Below is an example of a Public Key: 3048 0241 00C9 18FA CF8D EB2D EFD5 FD37 89B9 E069 EA97 FC20 5E35 F577 EE31 C4FB C6E4 4811 7D86 BC8F BAFA 362F 922B F01B 2F40 C744 2654 CODD 2881 D673 CA2B 4003 C266 E2CD CB02 0301 0001 (1) Explain the definition for both Public and Private Key.

It's hard to say without knowing what one is. In a few words, please explain.
Decode the number using the given private key. Decode the number M = 15 using the private key d = 53 and n= 77. Assume you are decoding the number using the RSA cryptosystem. Note: You can use the Modular Exponentiation calculator to help with the calculation.
In a RSA cryptosystem, a participant uses two prime numbers p and qis 17 and 11 respectively to generate his/her public key and privat keys. If the public key of participant is 7 and cipher text(C) is 11, then the original message(M) is. Correct answer will be appreciated , else downvoted.
