Trait Encrypting 

pub trait Encrypting<'a> {
    type EncryptedForm: 'a + Serialize;

    // Required method
    fn encrypt(
        &'a self,
        cipher: &Aes256Gcm,
    ) -> CryptoKeystoreResult<Self::EncryptedForm>;
}

This trait produces an encrypted form of this struct, where all sensitive fields have been encrypted using the EncryptData helper.

This is quite likely to be handled automatically by a macro, depending on how annoying it is to implement everywhere.

Example

// Foo is an Entity
struct Foo {
    id: Vec<u8>,
    sensitive_data: Vec<u8>, // sensitive!
}

#[derive(serde::Serialize)]
struct EncryptedFoo<'a> {
    id: &'a Vec<u8>,
    sensitive_data: Vec<u8>,
}

impl<'a> Encrypting<'a> for Foo {
    type EncryptedForm: EncryptedFoo<'a>;

    fn encrypt(&'a self, cipher: &aes_gcm::Aes256Gcm) -> CryptoKeystoreResult<EncryptedFoo<'a>> {
        Ok(EncryptedFoo {
            id: &self.id,
            sensitive_data: self.encrypt_data(cipher, &self.sensitive_data)?,
        })
    }
}

This can then be used like:

let json = serde_json::to_string(&foo.encrypt(cipher)?)?;

Required Associated Types

type EncryptedForm: 'a + Serialize

This type must be serializable, but can depend on the lifetime of self to reduce copying.

Required Methods

fn encrypt( &'a self, cipher: &Aes256Gcm, ) -> CryptoKeystoreResult<Self::EncryptedForm>

Make an instance of the encrypted form of this struct, for which all sensitive fields have been encrypted.
