FGLPROFILE entries

The fglprofile entries relating to Genero Web Services are divided between five categories: security, basic or digest HTTP authentication, proxy configuration, server configuration, and XML cryptography.

HTTPS and password encryption

The following table lists the FGLPROFILE file entries specifying the security certificates and algorithms the Web Services client uses for HTTPS and password encryption. These entries specify how an application using the low-level com or xml APIs performs secured communications.
Important: On iOS platform the security entries are not available because iOS SSL/TLS layer is used. However, you can configure the following security Web Services FGLPROFILE entries for GMI mobile devices: security.global.ca, security.global.ca.lookuppath, and security.global.systemca.
Note: Any entry defining a file on disk, for example security.global.ca, xml.keystore.calist, etc., can be set with a relative or an absolute path. If set as relative, the file is located based on the current execution directory. The recommended practice is to specify an absolute path in case fglrun is not always executed from the same directory.
Table 1. Security Configuration FGLPROFILE entries
Entry Description
security.global.script File name of a script executed each time a password of a private key is required by the client. The security script accepts one argument corresponding to the file name of the private key for which the password is required, and must return the correct password or the client stops. For script examples, see Windows® Password Script Example or UNIX™ Password Script Example. This entry cannot be used if security.global.agent is set.
security.global.agent Port number where the fglpass agent is waiting for requests. It returns the password that grants access to a private key when needed by a BDL application. The DVM and the fglpass agent perform authentication and exchange encrypted data over the local host network only. Refer to Using the password agent for details. This entry cannot be used if security.global.script is set.
security.global.agent.gid Set this entry as true to specify agent authentication based on OS user group. This entry is only for UNIX platforms. For more details, see Use the password agent.
security.global.protocol
Important: Since GWS version 3.10.22 this entry is no longer supported. Protocol defaults to the OpenSSL engine preference.

The SSL/TLS protocol to use for secured communications.

Possible values are:

  • TLSv1.2

  • TLSv1.1

  • TLSv1 (version 1.0)

  • SSLv3

  • SSLv23 (The default, enabling all supported protocols)
security.global.ca File name of the Certificate Authority list, with the concatenated PEM-encoded third party X.509 certificates considered as trusted, and in order of preference.
security.global.ca.lookuppath A list of directories containing certificate authorities. Genero Web Services will load the CA from the directories in this list. The entry is a list of directories separated by a semicolon.
security.global.windowsca If set to true, build the Certificate Authority list from the Certificate Authorities stored in the Windows key store. This entry is only valid on Windows systems where security.global.ca is not set.
security.global.cipher The list of encryption, digest, and key exchange algorithms the client is allowed to use during a secured communication. If this entry is omitted, all algorithms are supported. For more details about cipher, refer to www.openssl.org.
security.global.certificate File name of the PEM-encoded client X.509 certificate to be used for any secured connection if not redefined in a specific server configuration.
security.global.privatekey

File name of the PEM-encoded private key associated to the above X.509 certificate and to be used for any secured connection if not redefined in a specific server configuration.

If the PEM file is password protected, you need to use the security.global.script or security.global.agent entries to supply the passphrase to decrypt the private key.
security.global.keysubject The subject string of a X.509 certificate and its associated private key registered in the Windows key store to be used for any secured connection if not redefined in a specific server configuration. This entry is valid only on Windows systems.
security.global.systemca When set to true, the Certificate Authority is loaded from the key store on Mac® OSX or Windows systems, and from a predefined directory on Unix/Linux®. If set to false, the Certificate Authority is not loaded from the system-default location. Default is true. This entry is only valid where security.global.ca is not set.
security.global.ocsp.enable If set to true, once the server has been validated against local certificate authority, an additional request is performed to the certificate issuer's URL to ensure that no certificate has been revoked at time of connection. Default value is false (no additional request is done)
security.global.ocsp.url Instead of checking revocation to the URL inside the issuer's certificate, you can specify a fixed URL where all OCSP requests will be sent.

For example:

security.global.ocsp.url = "http://any_url"

By default, this entry is not set and the URL inside the certificate is used.
security.idsec.certificate File name of the PEM-encoded client X.509 certificate.
security.idsec.privatekey

File name of the PEM-encoded private key associated to the above X.509 certificate.

If the PEM file is password protected, you need to use the security.idsec.script or security.idsec.agent entries to supply the passphrase to decrypt the private key.
security.idsec.keysubject The subject string of a X.509 certificate and its associated private key registered in the Windows key store. This entry is valid only on Windows systems.
Note:
  1. The idsec keyword must be replaced with your own identifier, and all necessary entries must be set. See FGLPROFILE setting.
  2. If an entry is defined more that once, only the last occurrence is taken into account.

Basic or digest HTTP authentication

The following table lists the FGLPROFILE entries that specify the login and password to use in the case of HTTP authentication to a server or a proxy. The entries also specify the login and password to use in an application using the low-level com or xml API.

Table 2. HTTP basic or digest Authentication FGLPROFILE entries
Entry Description 
authenticate.ident.login
 The login identifying the client to a server during HTTP Authentication. 
authenticate.ident.password
 The password validating the login of a client to a server during HTTP Authentication. As passwords are never recommended to be in clear text, you must encrypt them with the fglpass tool. For more information, see FGLPROFILE password encryption. 
authenticate.ident.realm
 The string identifying the server to the client during HTTP Authentication. If the string does not match the server's string, authentication fails. This parameter is optional, but it is recommended that you check the server identity, especially if the server's location is suspicious. 
authenticate.ident.scheme
 One of the following strings representing the different HTTP Authentication mechanisms.
  • Anonymous (default value) - The client does not know anything about the server, and performs a first request to retrieve the server authentication mechanism. It then uses the login and password to authenticate to the server using the Basic or Digest mechanism, depending on the server's returned value.
  • Basic - The client authenticates itself to the server at first request, by sending the login and the password using the Basic authentication mechanism.
  • Digest - The client performs a first request without any login and password, to retrieve the server information before authenticating itself to the server in a second request using the Digest mechanism.
Note:
  1. The ident keyword must be replaced with your own identifier, and all necessary entries must be set. See FGLPROFILE setting.
  2. If an entry is defined more that once, only the last occurrence is taken into account.

Proxy configuration

The following table lists the FGLPROFILE entries that specify how the Web Services client communicates with a proxy. The entries specify the way an application using the low-level com or xml API communicates with a proxy.

Table 3. Proxy Configuration FGLPROFILE entries
Entry Description 
proxy.http.location
 Location of the HTTP proxy defined as host:port or ip:port. If the port is omitted, the port 80 is used. 
proxy.http.list
 The list of beginning host names, separated with semicolons, for which the Web Services client does not go via the HTTP proxy. 
proxy.http.authenticate
 The HTTP Authenticate identifier the Web Services client uses to authenticate itself to the HTTP proxy. 
proxy.https.location
 Location of the HTTPS proxy defined as host:port or ip:port. If the port is omitted, the port 443 is used 
proxy.https.list
 The list of beginning host names, separated with semicolons, for which the Web Services client does not go via this HTTPS proxy. 
proxy.https.authenticate
 The HTTP Authenticate identifier the Web Services client uses to authenticate itself to the HTTPS proxy.
Note: If an entry is defined more that once, only the last occurrence is taken into account.

IPv6 configuration

The following table lists the FGLPROFILE entries that specify how the Web Services client uses the IPv6 network protocol.

Table 4. IPv4 and IPv6 FGLPROFILE entries
Entry Description 
ip.global.version
 Defines the IP version to be used. Possible values are "4" (IPv4) or "6" (IPv6). By default, when this entry is not defined, the WS library will try to use IPv6 and fallback to IPv4, depending on the operating system. 
ip.global.v6.interface.name
Important: This entry is not supported on Microsoft™ Windows platforms.
 Defines the name of the network interface to be used for IPv6 link-local addresses. For example, this entry can get values such as "eth0", "en0", "ethernet_5". 
ip.global.v6.interface.id
 Defines the id of the network interface to be used for IPv6 link-local addresses. For example, this entry can get values such as "1", "2", "11".
Note: If an entry is defined more that once, only the last occurrence is taken into account.

Server configuration

The following table lists the FGLPROFILE entries that specify the correct way a Web Services client connects to an end point (usually a server). Notice that the entries specify also the way an application using the low-level com or xml API connects to an end point.

Table 5. Server Configuration FGLPROFILE entries
Entry Description 
ws.ident.url
 The end point URL of the server.

See Using * wildcards in server URLs.

 
ws.ident.regex.url
 A regular expression to define all possible URLs that can be used in this server configuration.
Note: If the ws.ident.url is defined, the regex.url entry is ignored.

This regex entry follows W3C rules as described in https://www.w3.org/TR/xmlschema-2/#regexs

See Using regular expressions in server URLs.

 
ws.ident.cipher
 The list of encryption, digest and key exchange algorithms the client is allowed to use during a secured communication to that server. It overwrites the global definition. 
ws.ident.verifyserver
 If set to true, the client performs a strict server identity validation. If not fulfilled, it stops the communication; otherwise no server identity verification is performed. The default value is true. 
ws.ident.security
 The security identifier the client uses to perform an HTTPS communication to the server. 
ws.ident.authenticate
 The HTTP authenticate identifier the client uses to authenticate itself to the server.
Note:
  1. The ident keyword must be replaced with your own identifier. All necessary entries, depending on the remote server's configuration, must be set. See FGLPROFILE setting.
  2. You can use the unique identifier in the .4gl code instead of the server URL, with the alias:// prefix. For example, alias://ident.
  3. If an entry is defined more that once, only the last occurrence is taken into account.

XML configuration

The following table lists the FGLPROFILE entries that control XML to Genero values conversion, and XML cryptography key or certificate mapping.

Table 6. XML configuration FGLPROFILE entries
Entry Description 
xml.keystore.calist
 The list of PEM-encoded third party X.509 certificates, separated with semicolons, of the Certificate Authority considered as trusted, in order of preference. 
xml.keystore.x509list
 The list of PEM-encoded third party X.509 certificates, separated with semicolons, to be used to find out the correct X.509 certificate when getting an incomplete one in a XML signature or an encrypted XML document. 
xml.ident.key
 The file name of a cryptography key. For instance RSA.pem, DSA.der or HMAC.bin. 
xml.ident.x509
 The file name of a cryptography x509 certificate. For instance Cert.crt. 
xml.serializer.supportEmptyStrings

Controls empty string XML nodes conversion to Genero STRING values.

The default is false, empty XML tags are converted to NULL.

If set to true, an empty XML tag is converted to an empty STRING value. As result, in Genero, the LENGTH() function will return zero and the IS NULL comparison operator will evaluate to FALSE.

Note that this entry only works for the STRING data type, and if the tag is not present, the STRING is set to NULL.

 
xml.signature.prefix = { "prefix" | "<none>" }

Defines the prefix for an XML Signature.

Use "<none>" to specify no prefix.

By default, the XML Signature prefix is "dsig".

 
xml.encryption.prefix = { "prefix" | "<none>" }

Defines the prefix for an XML Encrypted data.

Use "<none>" to specify no prefix.

By default, the XML Encrypted data prefix is "xenc".
Note:
  1. The ident keyword must be replaced with your own identifier. See FGLPROFILE sample 2.
  2. You can use the unique identifier in the .4gl code instead of the filename.
  3. If an entry is defined more that once, only the last occurrence is taken into account.
