Security

/ˌeɪtʃ-tiː-tiː-piː-ˈɛs/

n. “Talk securely or don’t talk at all.”

HTTPS, short for Hypertext Transfer Protocol Secure, is the secure version of HTTP, the foundational protocol of the web. It wraps standard web communication in an encrypted layer, usually via TLS, ensuring that data exchanged between a browser and server remains private and tamper-resistant.

/ˌpɒliˈwʌn-θɜːrtiː-fʌɪv/

n. “A tiny guardian watching every bit.”

Poly1305 is a cryptographic message authentication code (MAC) algorithm created by Daniel J. Bernstein, designed to verify the integrity and authenticity of a message. Unlike encryption algorithms that hide the content, Poly1305 ensures that data has not been tampered with, acting as a digital seal that can detect even a single-bit change in a message.

/ˈtʃɑː-tʃɑː-twɛn-ti/

n. “Fast. Portable. Secure — even when the hardware isn’t helping.”

ChaCha20 is a modern stream cipher designed to encrypt data quickly and securely across a wide range of systems, especially those without specialized cryptographic hardware. Created by Daniel J. Bernstein as a refinement of the earlier ChaCha family, ChaCha20 exists to solve a practical problem that older ciphers struggled with: how to deliver strong encryption that remains fast, predictable, and resistant to side-channel attacks on ordinary CPUs.

/ˈwaɪərˌɡɑːrd/

n. “Small, sharp, and unapologetically modern.”

WireGuard is a next-generation virtual private network protocol designed to do one thing extremely well: create fast, secure encrypted tunnels without dragging decades of legacy complexity along for the ride. Where older VPN systems grew layered, configurable, and occasionally fragile, WireGuard arrived with a different philosophy — fewer options, fewer lines of code, and far fewer places for mistakes to hide.

/ˈoʊpən-viː-piː-ɛn/

n. “A private tunnel built out of public roads.”

OpenVPN is an open-source virtual private networking protocol and software suite designed to create secure, encrypted connections across untrusted networks. It exists to solve a simple but dangerous problem: the internet is shared, noisy, and hostile, yet people still need to move private data across it without being watched, altered, or impersonated.

/ˌaɪ-piː-ˈɛsɛk/

n. “The armored lanes of your network traffic.”

IPSec, or Internet Protocol Security, is a suite of protocols designed to secure IP communications by authenticating and encrypting each IP packet in a data stream. It operates at the network layer, meaning it can protect all traffic crossing an IP network, from simple emails to complex enterprise applications. Its primary goals are confidentiality, integrity, and authenticity of the data in transit.

/ˌviː-piː-ˈɛn/

n. “Your private highway across the public internet.”

A VPN, or Virtual Private Network, is a technology that creates a secure, encrypted tunnel between your device and a remote server, allowing data to travel safely over untrusted networks like the internet. By masking your IP address and encrypting your traffic, VPNs protect your online identity, prevent eavesdropping, and can bypass geographic restrictions on content.

/ˌiː-siː-diː-ɛs-eɪ/

n. “Sign it once, prove it forever.”

ECDSA, or Elliptic Curve Digital Signature Algorithm, is a cryptographic signature scheme built on ECC principles. It allows someone to sign a message, document, or piece of data in a way that anyone else can verify the authenticity using the signer’s public key, while the private key remains secret. Unlike traditional signatures, ECDSA is compact, efficient, and provides strong security even with smaller key sizes.

/ˌiː-siː-diː-eɪtʃ/

n. “Shaking hands securely, without meeting.”

/ˌiː-siː-ˈsiː/

n. “Small curves, big security.”

ECC, or Elliptic Curve Cryptography, is a public-key cryptography system that uses the mathematics of elliptic curves over finite fields to create secure keys. Unlike traditional algorithms like RSA, which rely on the difficulty of factoring large integers, ECC relies on the hardness of the elliptic curve discrete logarithm problem. This allows ECC to achieve comparable security with much smaller key sizes, improving performance and reducing computational load.
