The SDK gives you many different ways to create and access wallets. Let's explore these different approaches in the following sub-chapters.
Note: Keep in mind that you should never share your private/secret key. And in the case of wallets that were derived from a mnemonic phrase, never share your mnemonic phrase.

Wallet::encrypt
to encrypt its content first before saving it to disk.
