Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):
- brain/ LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
dispatch, A51 channels, and the OSINT cluster
- knowledge/ LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
MITRE ATT&CK data
- reference/ defensive threat-reference (C3, shhbruh doc) + AdaYaml parser
License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.
Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

API Reference: Implementing AES Encryption for Data at Rest
cryptography Library - AESGCM
from cryptography.hazmat.primitives.ciphers.aead import AESGCM
import os
key = AESGCM.generate_key(bit_length=256)
aesgcm = AESGCM(key)
nonce = os.urandom(12) # 96-bit nonce, NEVER reuse
ciphertext = aesgcm.encrypt(nonce, plaintext, associated_data)
plaintext = aesgcm.decrypt(nonce, ciphertext, associated_data)
Key Derivation - PBKDF2
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC
from cryptography.hazmat.primitives import hashes
kdf = PBKDF2HMAC(
algorithm=hashes.SHA256(),
length=32, # 256-bit key
salt=os.urandom(16),
iterations=600_000, # NIST 2024 recommendation
)
key = kdf.derive(password.encode())
Encrypted File Format
[salt: 16 bytes][nonce: 12 bytes][ciphertext + tag: variable]
| Field | Size | Purpose |
|---|---|---|
| Salt | 16 bytes | PBKDF2 salt (random per file) |
| Nonce | 12 bytes | GCM nonce (random per encryption) |
| Ciphertext | Variable | Encrypted data + 16-byte auth tag |
AES Modes Comparison
| Mode | AEAD | Nonce Size | Use Case |
|---|---|---|---|
| GCM | Yes | 12 bytes | File/network encryption |
| CBC | No | 16 bytes | Legacy, disk encryption |
| CTR | No | 16 bytes | Streaming |
| XTS | No | 16 bytes | Full disk encryption |
Fernet (High-Level API)
from cryptography.fernet import Fernet
key = Fernet.generate_key()
f = Fernet(key)
token = f.encrypt(b"data")
plaintext = f.decrypt(token)
