UmbraCryptoService Module¶

The UmbraCryptoService module provides cryptographic operations and services for the UmbraCore framework.

Overview¶

UmbraCryptoService implements secure cryptographic functions required for encrypting and decrypting data, generating secure keys, and providing other essential cryptographic operations needed by the UmbraCore framework.

Features¶

Secure encryption and decryption operations
Cryptographic key generation and management
Password hashing with modern algorithms
Secure random data generation
Digital signature verification

Usage¶

import UmbraCryptoService

// Create a crypto service instance
let cryptoService = UmbraCryptoService()

// Generate a secure key
let key = try cryptoService.generateKey(
    strength: .high,
    purpose: .encryption
)

// Encrypt sensitive data
let encryptedData = try cryptoService.encrypt(
    data: sensitiveData,
    using: key,
    algorithm: .aes256GCM
)

// Decrypt the encrypted data
let decryptedData = try cryptoService.decrypt(
    data: encryptedData,
    using: key,
    algorithm: .aes256GCM
)

Integration¶

UmbraCryptoService integrates with:

SecurityTypes for core security primitives
SecurityProtocolsCore for protocol conformance
UmbraKeychainService for secure key storage
UmbraCore for high-level security operations

Security Considerations¶

Implements industry-standard cryptographic algorithms
Uses secure key management practices
Implements key rotation capabilities
Provides secure memory handling for sensitive data
