SSL (Secure Socket Layer)

What is SSL?

Secure Socket Layer (SSL) is a cryptographic protocol designed to secure communication over networks, primarily the internet. It provides:

Encryption – Data is encrypted end-to-end to prevent eavesdropping.
Authentication – Verifies server identity via digital certificates (e.g., issued by Let’s Encrypt or DigiCert).
Data Integrity – Ensures transmitted data isn’t altered in transit.

From SSL to TLS

Modern systems use Transport Layer Security (TLS), the successor to SSL (deprecated due to vulnerabilities like POODLE). Key versions:

TLS 1.2 (widely adopted)
TLS 1.3 (faster, more secure, drops legacy cipher suites)

How SSL/TLS Works

Handshake Phase:

Client sends supported cipher suites (e.g., AES256-GCM-SHA384).
Server responds with a certificate and selects a cipher.
Keys are exchanged (via RSA or ECDHE).

Encrypted Session: Application data (e.g., HTTP requests) is encrypted.

SSL Fingerprinting & Anti-Detect Browsers

Browsers reveal SSL/TLS fingerprints through:

Supported cipher suites (e.g., Chrome vs. Firefox differences).
TLS extensions (e.g., ALPN, SNI).
Signature algorithms (e.g., SHA-256).

Why it matters for FlashID:
Anti-detect browsers must mimic real devices by replicating unique SSL fingerprints. FlashID dynamically adjusts these parameters to:

Avoid detection (e.g., blocking by websites analyzing TLS handshakes).
Prevent linkage of multiple accounts via shared browser signatures.

Common SSL/TLS Use Cases

HTTPS websites (SSL certificates padlock in browsers).
VPNs & secure email (e.g., SMTP over TLS).
API security (e.g., OAuth 2.0 with TLS encryption).
