Struct AnonymizationPolicy 

pub struct AnonymizationPolicy {
    pub ip_mode: IpAnonymizationMode,
    pub mac_mode: MacAnonymizationMode,
    pub port_mode: PortAnonymizationMode,
    pub timestamp_mode: TimestampAnonymizationMode,
    pub tcp_seq_mode: TcpSeqAnonymizationMode,
    pub payload_mode: PayloadAnonymizationMode,
    pub crypto_pan_key: Option<[u8; 32]>,
    pub hash_salt: Option<[u8; 32]>,
}

Master anonymization policy.

Controls which cryptographic primitives and strategies are applied to each protocol field category during flow export.

Example

use stackforge_core::anonymize::AnonymizationPolicy;

// ML-optimized defaults: prefix-preserving IPs, hashed MACs,
// well-known ports preserved, epoch-shifted timestamps, payload stripped.
let policy = AnonymizationPolicy::ml_optimized();

Fields

ip_mode: IpAnonymizationMode

IP address anonymization strategy.

mac_mode: MacAnonymizationMode

MAC address anonymization strategy (applied if MAC data is present in flow metadata – currently informational for future packet-level anonymization).

port_mode: PortAnonymizationMode

Transport port anonymization strategy.

timestamp_mode: TimestampAnonymizationMode

Timestamp anonymization strategy.

tcp_seq_mode: TcpSeqAnonymizationMode

TCP sequence number anonymization strategy.

payload_mode: PayloadAnonymizationMode

Reassembled payload handling.

crypto_pan_key: Option<[u8; 32]>

32-byte key for Crypto-PAn. First 16 bytes = AES-128 key, last 16 bytes = padding material.

If None and ip_mode is CryptoPan, a random key is generated.

hash_salt: Option<[u8; 32]>

32-byte salt for consistent hashing (MAC addresses, connection IDs).

If None, a random salt is generated per engine session.

Implementations

impl AnonymizationPolicy

pub fn ml_optimized() -> Self

Policy optimized for machine learning on network flows.

• IPs: Crypto-PAn (preserves subnet topology)
• Ports: well-known destination ports preserved
• Timestamps: epoch shift (perfect ordering)
• TCP seq: random per-flow offset
• Payloads: fully truncated

pub fn maximum_privacy() -> Self

Maximum privacy policy. Generalizes all ports, hashes all MACs, and strips payloads.
