Cryptic - keeps your secrets
summary
Cryptic is a Scala library that encrypts individual fields via an Encrypted-typeclass and defers transformations until explicit decryption using staged operations so map/flatMap build without exposing keys. It provides codecs (upickle, chill, FST) and requires an encrypt/decrypt function (currently synchronous) so you can plug AES, RSA, ECC and an AES/RSA hybrid; manifests store non-secret metadata like key IDs and key maps allow per-entity key usage. Toy ciphers illustrate APIs; real implementations hide Java crypto details.
