# TO encrypt a message M using RSA cryptography with public jey pq and e, you use the formula ______, and to decrypt a message C, you use the forula____, where_____

To determine

To fill in the blanks of the statement “To encrypt a message M using RSA cryptography with public key pqande, you use the formula ______ and to decrypt a message C, you use the formula ______, where _______.”

Explanation

Given:

The statement “To encrypt a message M using RSA cryptography with public key pqande, you use the formula ______ and to decrypt a message C, you use the formula ______, where _______.”

To encrypt a message using RSA cryptography, break the message into blocks, each consisting of a single letter and find the numerical equivalent for each block.

The plaintext M in a block is converted into cipher text C by using the formula,

C=Me(modpq)

To decrypt a message using RSA cryptography, we use the formula,

M=Cd(modpq)

Where, disapositiveinverseforemodulo(p1)(q1)
