get_modulus: The ciphertext modulus

In openfhe.R: R Interface to the 'OpenFHE' Fully Homomorphic Encryption Library

The ciphertext modulus

Description

The modulus of an object, as a string of decimal digits, because it normally exceeds what an R number holds exactly.

Usage

get_modulus(x, ...)

Arguments

x	A CryptoContext or an ElementParams object.
...	Reserved for future method-specific arguments.

Details

For a CryptoContext or an ElementParams object it is the composite ciphertext modulus Q, the product of the RNS moduli. openfhe-python returns this value for a CryptoContext as a floating-point number; R returns it exactly.

Value

A character string of decimal digits.
