README
A pure-PHP library for Secure RTP (SRTP) and SRTCP packet encryption and decryption. It supports the AES-CM and AES-GCM protection profiles used by WebRTC without requiring OpenSSL or libsrtp FFI bindings.
About this fork
This is the danog/php-rtc-srtp fork used by MadelineProto. It targets PHP 8.2+, replaces the upstream libsrtp binding with an RFC 3711/RFC 7714 implementation backed by phpseclib, and includes interoperability fixes verified against pion/srtp.
All internal Composer dependencies use their danog/php-rtc-* package names directly, so installing a component selects the maintained danog packages throughout the dependency graph.
Features
- AES-GCM and AES-CM encryption for RTP/RTCP packets
- HMAC-SHA1 authentication
- Replay protection
- Interoperable with standard WebRTC implementations
Requirements
- PHP ≥ 8.2
- phpseclib 3 (installed through Composer)
- Linux environment (Windows/macOS support planned)
