[RFC idea] DTLS support in ext/openssl (Openssl\Dtls)
A PHP internals RFC proposal to add DTLS (Datagram TLS, the UDP counterpart of TLS) support to ext/openssl. The author proposes a transport-agnostic Openssl\Dtls class using memory BIOs, allowing applications to control packet flow for protocols like WebRTC, DTLS-SRTP, and CoAP. A working proof-of-concept with .phpt tests already exists. The proposal raises open questions about API design (enums vs int constants, object vs PEM string inputs, DtlsDatagram wrapper), whether DTLS belongs in core or userland/FFI, and how to handle the HelloVerifyRequest DoS mitigation. A community member suggests using proper PHP types (enums, typed objects) instead of raw strings and ints throughout the API.
