## Windows Native SSL: Secure Communication

(require net/win32-ssl) | package: base

The net/win32-ssl module offers a fraction of the functionality of openssl and works only on Windows, but it has the advantage that it works before OpenSSL libraries are installed.

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

Analogous to ssl-abandon-port.

Analogous to ports->ssl-ports.

If hostname verification is enabled via 'secure, the peer server’s certificate is checked against hostname.

Changed in version 6.3.0.12 of package base: Added the #:hostname argument.

> procedure (win32-ssl-port? v) → boolean?
> v : any/c

Returns #t of v is an SSL port produced by win32-ssl-connect or ports->win32-ssl-ports.

> value win32-ssl-available? : boolean?

A boolean value that reports whether the Windows native SSL library was successfully loaded. Calling win32-ssl-connect, etc. when this value is #f will raise an exception.
