impl CKKSEncryptor

pub fn homomorphic_length(&self, encrypted_poly: &Polynomial) -> usize

Function to calculate the homomorphic length of an encrypted string. This is the number of non-zero coefficients in the encrypted polynomial.

pub fn concatenate_encrypted_strings( &self, encrypted_poly1: &Polynomial, encrypted_poly2: &Polynomial, ) -> Polynomial

Function to concatenate two encrypted strings by combining their encrypted polynomials. This will create a new polynomial containing the coefficients of both encrypted strings.

pub fn extract_encrypted_substring<R>( &self, encrypted_poly: &Polynomial, range: R, ) -> Polynomial

where R: RangeBounds<usize>,

Extracts a substring from an encrypted string, using Rust range syntax.

• encrypted_poly: The encrypted string as a polynomial.
• range: A range representing the indices to extract (e.g., 0..3, 3.., ..5).
