order to force libcurl enums of being type int (the pragma disposition in use
before inclusion is restored before resuming the including unit compilation).
- Three SSL implementations were present in libcurl. Nevertheless, none of them
-is available on OS/400. To support SSL on OS/400, a fourth implementation has
-been added (qssl.[ch]). There is no way to have different certificate stores
-for CAs and for personal/application certificates/key. More, the SSL context
-may be defined as an application identifier in the main certificate store,
-or as a keyring file. As a consequence, the meaning of some fields have been
-slightly altered:
-_ The "certificate identifier" is taken from CURLOPT_SSLCERT if defined, else
-from CURLOPT_CAINFO.
-_ The certificate identifier is then used as an application identifier in the
-main certificate store. If successful, this context is used.
-_ If the previous step failed, the certificate identifier is used as the file
-name of a keyring. CURLOPT_KEYPASSWD is used here as the keyring password.
-_ The default ca-bundle (CURLOPT_CAINFO) is set to the main certificate store's
-keyring file name: this allows to use the system global CAs by default. (In that
-case, the keyring password is safely recovered from the system... IBM dixit!)
+ Two SSL implementations are available to libcurl on OS/400: QsoSSL which is
+obsolescent, does not support asynchronous I/O and only allows a single SSL
+context within a job, and GSKit that does not suffer from these limitations
+and is able to provide some information about the server certificate.
+ Both implementations of SSL are working on "certificate stores" or keyrings,
+rather than individual certificate/key files. Certificate stores, as weel as
+"certificate labels" are managed by external IBM-defined applications.
+ There are two ways to specify an SSL context:
+- By an application identifier.
+- By a keyring file pathname and (optionally) certificate label.
+ To identify an SSL context by application identifier, use option
+SETOPT_SSLCERT to specify the application identifier.
+ To address an SSL context by keyring and certificate label, use CURLOPT_CAINFO
+to set-up the keyring pathname, CURLOPT_SSLCERT to define the certificate label
+(omitting it will cause the default certificate in keyring to be used) and
+CURLOPT_KEYPASSWD to give the keyring password. If SSL is used without
+defining any of these options, the default (i.e.: system) keyring is used for
+server certificate validation.
