Windows Native SSL: Secure Communication🔗ℹ

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.

procedure
(win32-ssl-connect hostname
port-no
[ client-protocol])
→
(and/c input-port? win32-ssl-port?)
(and/c output-port? win32-ssl-port?)
  hostname : string?
  port-no : (integer-in 1 65535)
   client-protocol :
(or/c 'secure 'auto
      'sslv2-or-v3 'sslv2 'sslv3 'tls 'tls11 'tls12)
= 'auto

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

procedure
(win32-ssl-abandon-port in) → void?
in : (and/c win32-ssl-port? output-port?)

Analogous to ssl-abandon-port.

procedure
(ports->win32-ssl-ports input-port
output-port
#:encrypt protocol
[ #:hostname hostname])
→
(and/c input-port? win32-ssl-port?)
(and/c output-port? win32-ssl-port?)
  input-port : input-port?
  output-port : output-port?
   protocol :
(or/c 'secure 'auto
      'sslv2-or-v3 'sslv2 'sslv3 'tls 'tls11 'tls12)
  hostname : (or/c #f string?) = #f

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.
