Keccak256 calculates and returns the Keccak256 hash of the input data.

NewCipherText creates a new Ciphertext instance with encryption of the provided value.

NewCipherTextFromBytes creates a new Ciphertext from its byte representation.

NewCipherTextTrivial creates a new Ciphertext using trivial encryption - trivial encryption is used to encrypt "public" constants to inject into FHE operations.

NewKeccakState creates a new KeccakState.

NewRandomCipherText creates a random Ciphertext - only not really.

For now track this in a global, but this is kind of messy.

Ciphertext represents the encrypted data structure.
