fhe_serialize(x, ...)

Arguments

x	A CryptoContext, PublicKey, PrivateKey, Ciphertext, EvalKey or EvalKeyMap, or a list of EvalKey objects (in memory only). For Binary FHE, a BinFHEContext, LWECiphertext, LWEPrivateKey, LWEPublicKey or RingGSWBTKey (to a file only).
...	Method arguments: filename, a path, or NULL (default) to serialize in memory; format, "binary" (default) or "json".
