Pretty Good Privacy (PGP) sounds complicated, but it's actually the most elegant solution to a fundamental problem: how do you communicate securely with someone you've never met, over a network you don't trust? This is the exact challenge facing every user of Torzon Market, and PGP is our answer.
What is PGP and Why Does It Matter?
At its core, PGP is a cryptographic system that combines symmetric and asymmetric encryption to provide both confidentiality and authentication. When you generate a PGP key pair, you create two mathematically linked keys: a public key that you share with the world, and a private key that you guard with your life. Anyone can use your public key to encrypt a message that only you can decrypt with your private key. Conversely, you can use your private key to digitally sign a message, allowing anyone with your public key to verify that the message genuinely came from you and hasn't been tampered with.
For Torzon Market users, this dual functionality is critical. When you place an order, your shipping address must be encrypted with the vendor's public key. This ensures that even if the Torzon Market database is compromised, or if law enforcement seizes the servers, your personal information remains protected. Only the vendor, holding the corresponding private key, can decrypt and read your address. This is end-to-end encryption in its purest form—no intermediary, not even the platform itself, can access your sensitive data.
PGP Implementation on Torzon Market
We mandate the use of GnuPG 2.3.7 or later, the free and open-source implementation of the OpenPGP standard. We require 4096-bit RSA keys for all user accounts registered after February 2024. While 2048-bit keys are still considered secure for most purposes, we believe in future-proofing our security architecture. A 4096-bit RSA key provides a significantly larger security margin against advances in computational power and cryptanalysis.
Every vendor on Torzon Market must upload their PGP public key during registration. This key is displayed prominently on their profile page and is cryptographically signed by the platform to prevent key substitution attacks. When you navigate to a vendor's page, you should independently verify the key fingerprint against multiple sources—never trust a single source for critical security information.
Key Management Best Practices
Your private key is the crown jewel of your Torzon Market security. If it is compromised, an attacker can decrypt all past communications encrypted with your public key and impersonate you by signing messages. Here are our recommended best practices:
- Generate Keys Offline: Create your PGP key pair on an air-gapped computer that has never and will never connect to the internet. This eliminates the risk of keyloggers or malware stealing your private key during generation.
- Use Strong Passphrases: Your private key should be protected by a passphrase of at least 20 characters, combining random words, numbers, and symbols. Use a diceware passphrase generator for maximum entropy.
- Backup Securely: Store encrypted backups of your private key in multiple physical locations. Use encrypted USB drives or printed paper backups stored in secure locations. Never store unencrypted backups in cloud storage or on internet-connected devices.
- Key Rotation: Rotate your PGP keys every 12-18 months. This limits the window of vulnerability if a key is ever compromised. When rotating, securely delete old private keys using tools like
shredon Linux or secure erase utilities on other platforms. - Revocation Certificates: Generate and store a revocation certificate when you create your key pair. This allows you to invalidate your public key if your private key is ever compromised. Store the revocation certificate separately from your private key.
Digital Signatures and Message Authentication
PGP's signature capability is just as important as its encryption function. When Torzon Market publishes a list of verified mirror links, that list is signed with the platform's official PGP key. Before trusting any link, you must verify this signature. The verification process proves three things:
- Authenticity: The message was created by someone who possesses the private key corresponding to the published public key.
- Integrity: The message has not been altered since it was signed. Even a single character change will cause signature verification to fail.
- Non-Repudiation: The signer cannot later deny having created the message, as only they possess the private key required to generate that specific signature.
Similarly, vendors should sign all communications with buyers. This prevents impersonation attacks where a third party poses as a vendor to extract sensitive information or redirect payments. Always verify signatures before trusting any message claiming to be from a vendor or the Torzon Market administration. See our detailed PGP tutorial for step-by-step verification instructions.
PGP Limitations and Operational Security
While PGP is powerful, it's not a magic bullet. The cryptography is sound, but implementation and operational security are where most failures occur. Common mistakes include:
- Compromised Systems: If you generate or use your PGP keys on a malware-infected computer, all bets are off. Attackers can log your passphrase, copy your private key, or intercept messages before encryption.
- Metadata Leakage: PGP encrypts the content of messages, but not metadata like sender, recipient, timestamp, or message size. This metadata can still reveal patterns of communication.
- Forward Secrecy: Standard PGP does not provide forward secrecy. If your private key is compromised, all past messages encrypted with the corresponding public key can be decrypted. This is why key rotation is so important.
