## What it is
CryptoSwift is a pure Swift library providing standard cryptographic algorithms including AES, ChaCha20, SHA family hashes, HMAC, and CRC. It offers convenient Swift extensions and streaming APIs across Apple platforms, Linux, and Android.

## Use cases
- encrypt and decrypt data with AES in Swift
- compute SHA-256 or MD5 hashes of strings or files
- generate HMAC signatures for API authentication
- implement ChaCha20 stream cipher encryption
- calculate CRC32 checksums in Swift
- hash passwords and verify digests cross-platform on Linux

## When to choose
- you need pure Swift crypto without C dependencies like CommonCrypto
- you want convenient String/Data extensions for hashing and encryption
- you target Apple platforms plus Linux or Android with one codebase
- you need streaming or incremental hash/cipher updates

## When to avoid
- you need formally audited or constant-time crypto for highly sensitive production secrets
- you only need Apple-platform crypto and can use the system CommonCrypto/CryptoKit
- you need advanced protocols like TLS, certificates, or public-key infrastructure
- you require FIPS-validated implementations

## Facets
- artifact type: library
- maturity: active
- function: cryptography, security, serialization
- domain: security, developer-tools, cross-platform
- platform: cross-platform
- tags: aes, hashing, hmac, chacha20, pure-swift, digest, ciphers, sha3, swift-package-manager, macos, ios, linux, android, swift
