Today we'll use the XTEA encryption/decryption code we loaded last time. It's a simple tool, and easy to use for small projects without terribly solid encryption needs. To get started, just use code like this: The first 16 characters are your key:
cipher := 'this is my string for encryption/decryption'
xteaEncryptWithKey: 'my encryption key'.
That encrypts; you can inspect the cipher to see the binary data. Next, use the same key to decrypt it:
plain := cipher xteaDecryptWithKey: 'my encryption key' 'this is my string for encryption/decryption'
That's it - for simple use cases, that's all you need.
