Cryptic

Keeps your secrets. Cryptic is a monad for encrypting and decryptic data. To use cryptic you must select a crypto and a serializer.

Cryptic supports several crypto libraries and serializers, select the modules you nedd or write your own

Module	Supports
crypto-javax	AES, RSA
crypto-bouncycastle	ECIES (Elliptic curve)
serialization-fst	FST

Installation

sbt

"scalacrypto" %% "core" % "1.0.0"
"scalacrypto" %% "serialization-fst" % "1.0.0"

To use AES or RSA

"scalacrypto" %% "crypto-javax" % "1.0.0"

Usage

Import base package and syntax extension:

import cryptic._
import cryptic.syntax._

Define your data types:

case class EmailAddress(literal: String)
case class User(id: Long, email: Encrypted[EmailAddress])

Encrypt your data using convenient syntax (a crypto and a serializer must be available):

import java.security.{KeyPair, PrivateKey, PublicKey}
import cryptic.serialization.Fst._
import cryptic.syntax._
import cryptic.crypto.ECIES

// We need an implicit public key to enable encryption
private val keyPair: KeyPair = ECIES.keygen(256)
implicit private val publicKey: PublicKey = keyPair.getPublic

val user = User(123, EmailAddress("odd@example.com").encrypted)

Access your data in encrypted form (can be done without crypto/serializer):

val bytes: Array[Byte] = user.email.bytes

Transform your data (can be done without crypto/serializer):

val lowered = user.email.
    map(_.copy(literal = _.literal.toLower))

Run your staged transformations (a crypto and a serializer must be available):

import cryptic.crypto.RSA._
import cryptic.serialization.Fst._

val user2 = user.copy(
  email = lowered.run())

Decrypt your transformed data (a crypto and a serializer must be available):

import cryptic.crypto.RSA._
import cryptic.serialization.Fst._

val emailInLower = user2.email.decrypted
