You can now define optional fields. These do not encrypt when NULL is provided as a value. Instead, they become an unencrypted NULL. EncryptedRow: - foo, OptionalText - bar, OptionalText Plaintext: ['foo' => 'abc', 'bar' => null] Ciphertext: ['foo' => /* encrypted */, 'bar' => null] These are called "optional" types to disambiguate with NULL support. This matters because Boolean fields always supported NULL under-the-hood. ## Types Mapping with Optional - Boolean: - (true) -> (ciphertext) - (false) -> (ciphertext) - (null) -> (ciphertext) - Integer: - (int) -> (ciphertext) - (null) -> TypeError - Float: - (float) -> (ciphertext) - (null) -> TypeError - JSON: - (json) -> (ciphertext) - (null) -> TypeError - Text: - (string) -> (ciphertext) - (null) -> TypeError - OptionalBoolean: - (true) -> (ciphertext) - (false) -> (ciphertext) - (null) -> (null) - OptionalInteger: - (int) -> (ciphertext) - (null) -> (null) - OptionalFloat: - (float) -> (ciphertext) - (null) -> (null) - OptionalJSON: - (json) -> (ciphertext) - (null) -> (null) - OptionalText: - (string) -> (ciphertext) - (null) -> (null)
