Classes

ASECiphertextKEM: This class represents the ciphertext for the ASE KEM scheme. It contains a polynomial vector u and a polynomial v.
ASECombinedCipher: Final class for the combined ciphertext It contains the KEM ciphertext, nonce, ciphertext, AAD, and salt
ASEKeyPair: This class represents the key pair for the ASE KEM scheme. It contains a public key and a private key.
ASEPrivateKey: This class represents the private key for the ASE KEM scheme. It contains a polynomial vector s.
ASEPublicKey: This class represents the public key for the ASE KEM scheme. It contains a list of polynomial vectors A and a polynomial b.

decryptString(ASECombinedCipher cc, ASEPrivateKey sk) → Future<String>: Decrypts a string using the hybrid PKE scheme It uses the private key (sk) to generate a shared secret and then uses AES-GCM to decrypt the ciphertext (ct)
deserializeCombinedCipher(String path) → ASECombinedCipher: Deserializes the combined ciphertext from a JSON file The file should contain a JSON object with the keys 'kemCt', 'nonce', 'ciphertext', and 'salt'.
deserializePublicKey(String path) → ASEPublicKey: Deserializes the public key from a JSON file The file should contain a JSON object with the keys 'A' and 'b'.
encryptString(String pt, ASEPublicKey pk) → Future<ASECombinedCipher>: Encrypts a string using the hybrid PKE scheme It uses the public key (pk) to generate a shared secret and then uses AES-GCM to encrypt the plaintext (pt)
serializeCombinedCipher(ASECombinedCipher cc) → String: Deserializes the public key from JSON format
serializePublicKey(ASEPublicKey pk) → String: Serializes the public key to JSON format
