A comprehensive TypeScript security library providing cryptographic primitives and utilities with a focus on type safety, security, performance, and modern best practices.
-
🔒 Cryptographic Primitives
- AES encryption (128/192/256-bit) with multiple modes (ECB, CBC, CFB, OFB, CTR, GCM)
- SHA-2 family hash functions (SHA-256, SHA-384, SHA-512)
- HMAC message authentication
- RSA encryption and signing
- Ed25519 digital signatures
-
🛡️ Secure Random Number Generation
- Fortuna CSPRNG implementation
- Multiple entropy sources
- Automatic reseeding
- Browser and Bun / Node.js support
-
📜 Certificate Management
- X.509 certificate handling
- PEM encoding/decoding
- Certificate signing request (CSR) creation
- Certificate chain validation
-
🔐 TLS/SSL Support
- TLS protocol implementation
- Secure socket connections
- Certificate-based authentication
- Modern cipher suite support
-
🎯 Type Safety
- Full TypeScript support
- Comprehensive type definitions
- Strict type checking
- Modern ES6+ features
-
🧰 Utilities
- Base-N encoding (Base64, Base58, etc.)
- ASN.1 encoding/decoding
- BigInteger arithmetic
- Buffer manipulation
# bun
bun install ts-security
# npm
npm install ts-security
# pnpm
pnpm install ts-securityAfter installing the package, you can import and use the various cryptographic functions:
import {
aes,
ed25519,
hmac,
pki,
random,
rsa,
sha256,
sha512,
tls
} from 'ts-security'
// AES Encryption
const cipher = aes.createCipher('AES-GCM', key)
cipher.start({ iv })
cipher.update(data)
const encrypted = cipher.finish()
// SHA-256 Hashing
const md = sha256.create()
md.update('Hello, World!')
const hash = md.digest().toHex()
// Secure Random Numbers
const bytes = random.getBytesSync(32)
// RSA Key Generation
const keypair = rsa.generateKeyPair({ bits: 2048 })
// Digital Signatures
const signature = ed25519.sign(message, privateKey)
const isValid = ed25519.verify(signature, message, publicKey)
// Certificate Operations
const cert = pki.createCertificate()
cert.publicKey = keypair.publicKey
cert.sign(keypair.privateKey)
// TLS Connections
const connection = tls.connect({
server: host,
port: 443,
caStore: [/* trusted certificates */]
