## What it is
SwiftyRSA is a Swift library for RSA public/private key encryption and decryption on Apple platforms. It supports loading keys from PEM, DER, Base64, data, or SecKey references and encrypting/decrypting strings with PKCS1 padding.

## Use cases
- encrypt sensitive data like license numbers with an RSA public key in an iOS app
- decrypt RSA-encrypted payloads with a private key in Swift
- load PEM or DER public/private keys in an iOS or macOS app
- wrap SecKey references in a friendlier Swift API for RSA operations
- produce base64-encoded RSA ciphertext to send to a backend API

## When to choose
- you need RSA encryption/decryption in Swift on iOS, tvOS, watchOS, or macOS
- you want simple PEM/DER key loading and PKCS1 padding out of the box
- you need an Objective-C-compatible RSA pod

## When to avoid
- you need modern asymmetric crypto like Ed25519 or X25519 rather than RSA
- you need full TLS or certificate handling rather than raw RSA
- you are not on an Apple/Swift platform

## Facets
