# Mac OS Native SSL: Secure Communication🔗ℹ

(require net/osx-ssl) | package: base

The net/osx-ssl module offers a fraction of the functionality of openssl and works only on Mac OS, but it has the advantage that it works before OpenSSL libraries are installed.

Added in version 6.3.0.12 of package base.

Like ssl-connect, but without support for client contexts.

Analogous to ssl-abandon-port.

> procedure (osx-ssl-output-port? v) → boolean?
> v : any/c

Returns #t of v is an SSL output port produced by osx-ssl-connect.

> procedure (osx-old-openssl?) → boolean?

Returns #t if the OpenSSL library currently accessed by openssl is too old, in which case osx-ssl-connect should be preferred.
