Hello everyone, I am trying to serialize and deserialize a CKKSRNS Context and keys.

I am able to do it with the context like this:

```auto
if (!Serial::SerializeToFile("crypto-context.txt", cryptoContext, SerType::BINARY)) {
    std::cerr << "Error writing serialization of the crypto context to crypto-context.txt" << std::endl;
}

```

and later, deserializing like this:

```auto
CryptoContext<DCRTPoly> cryptoContext;
if (!Serial::DeserializeFromFile("crypto-context.txt", cryptoContext, SerType::BINARY)) {
    cerr << "I cannot read serialization from " << "cryptocontext.txt" << endl;
}

```

I can do it with keys, too:

```auto
if (!Serial::SerializeToFile("key-public.txt", keyPair.publicKey, SerType::BINARY)) {
    std::cerr << "Error writing serialization of public key to key-public.txt" << std::endl;
}

```

Deserialization:

```auto
PublicKeyImpl<DCRTPoly> pk;

if (!Serial::DeserializeFromFile("key-public.txt", pk, SerType::BINARY)) {
    cerr << "Could not read public key" << endl;
}

```

But in documentations ([Here](https://openfhe-development.readthedocs.io/en/latest/sphinx_rsts/intro/using_the_library.html?highlight=serialization#serialization)), it says that there are various functions like `DeserializePublicKey`, `DeserializeSecretKey` and so on, but I am unable to find them.

Is my code correct?

Thank you!

Hi, your code is correct and you should keep using SerializeToFile() and DeserializeFromFile() . I will correct the documentation. Thank you for pointing that out.
