OpenSSL

Platform/OpenSsl/ wraps OpenSSL for TLS transport and keyed at-rest crypto (OpenSSL documentation).

Fills the Stream role with TLS, and the SecurityPolicy role for at-rest integrity.

What it ships

Class	Role
SolidSyslogTlsStream	TLS stream — server-cert + hostname verification, cipher pinning, optional mutual TLS
SolidSyslogOpenSslHmacSha256Policy	at-rest HMAC-SHA256
SolidSyslogOpenSslAesGcmPolicy	at-rest AES-256-GCM

Requirements

OpenSSL 3.0 or later.
