How does this skill handle SIP Digest Authentication?

It provides ready-to-use TypeScript implementations for the HTTP Digest challenge-response flow, including A1/A2 hash calculations, nonce generation, and credential response verification.

Does it support modern hashing algorithms?

Yes, the skill includes logic for both the standard MD5 algorithm and the more secure SHA-256 variant for SIP authentication.

Can I use this for both client and server development?

Absolutely. It contains patterns for clients to respond to challenges and for servers/registrars to issue challenges and verify incoming credentials.

Is TLS support included for SIPS?

Yes, the skill provides architectural patterns and best practices for implementing TLS encryption to enable secure SIPS signaling.

Security & Testing

Implements secure SIP authentication mechanisms and encryption patterns for VoIP applications and infrastructure.

About

This skill empowers developers to build secure VoIP systems by providing standardized implementations for SIP authentication and encryption. It covers the full lifecycle of SIP security, from generating HTTP Digest challenges and calculating responses to implementing TLS-based SIPS communication. Whether you are building a SIP client, server, or proxy, this skill provides the domain-specific logic needed to handle credentials, nonces, and secure headers while following industry best practices for telecommunications security and registration protection.
