Parameter	Description	Example	Flags
curl	The CURL session handle.	$curl
Value	The file path for the certificates.	"/test.pem"
Encoding	The text encoding for text parameter. Default is UTF-8. Possible encoding names: ANSI, ISO-8859-1, Latin1, Mac, Native, UTF-8, DOS, Hex, Base64 or Windows. More listed in the FAQ.	"UTF8"	Optional

Result

Returns "OK" on success.

Description

Sets a path to find certificate file.
Pass a string naming a file holding one or more certificates to verify the peer with. This makes sense only when used in combination with the CURL.SetOptionVerifyPeer option. If CURL.SetOptionVerifyPeer is zero, CURL.SetOptionCAINFO need not even indicate an accessible file.

This option is by default set to the system path where libCURL's cacert bundle is assumed to be stored, as established at build time.

When built against NSS, this is the directory that the NSS certificate database resides in.

Starting with version 8.0 the plugin will always use UTF-8 encoding for file path on Linux and macOS. For macOS we also do the unicode character normalization for file names for you.

Examples

Enables verification and uses cacert.pem file for certificates:

MBS( "CURL.SetOptionCAINFO"; $curl; $cacertPath )
MBS( "CURL.SetOptionSSLVerifyHost"; $curl; 2 )
MBS( "CURL.SetOptionSSLVerifyPeer"; $curl; 1 )

Use FileMaker's root file in CURL:

Set Variable [ $curl ; Value: MBS("CURL.New") ]
#
If [ MBS("IsIOS") ]
# look for path to certificate file
Set Variable [ $path ; Value: Substitute(MBS("Folders.UserDocuments"); "/Documents"; "/Library/Application Support/FileMaker/iOS/1.0/root.pem") ]
If [ MBS("Files.FileExists"; $path) ]
# use in CURL
Set Variable [ $r ; Value: MBS( "CURL.SetOptionCAINFO"; $curl; $path) ]
Else
Show Custom Dialog [ "File not found." ; $path ]
End If
Else If [ MBS("IsMacOSX") ]
# look for path to certificate file
Set Variable [ $path ; Value: Substitute(MBS("Folders.UserDocuments"); "/Documents"; "/Library/Application Support/FileMaker/Shared/17.0/root.pem") ]
If [ MBS("Files.FileExists"; $path) ]
# use in CURL
Set Variable [ $r ; Value: MBS( "CURL.SetOptionCAINFO"; $curl; $path) ]
Else
Show Custom Dialog [ "File not found." ; $path ]
End If
Else If [ MBS("IsWindows") ]
# look for path to certificate file
Set Variable [ $path ; Value: Substitute(MBS("Folders.UserDocuments"); "\Documents"; "\AppData\Local\FileMaker\FileMaker Pro Advanced\17.0\root.pem") ]
If [ MBS("Files.FileExists"; $path) ]
# use in CURL
Set Variable [ $r ; Value: MBS( "CURL.SetOptionCAINFO"; $curl; $path) ]
Else
Show Custom Dialog [ "File not found." ; $path ]
End If
Else If [ MBS("IsLinux") ]
# look for path to certificate file
Set Variable [ $path ; Value: "/FileMakerData/Extensions/OpenSSL/root.pem" ]
# use in CURL
Set Variable [ $r ; Value: MBS( "CURL.SetOptionCAINFO"; $curl; $path) ]
End If
