This library serves to digitally sign an XML document. It has one function: signDoc that takes 10 parameters to be set first and the function is then called.
For the time being it supports the "PKCS12" store type. Other types are not tested.
Paramaters and function:
-XmlDocDir : Directory of the xml document to be signed.
-XmlDocName : Name of the xml document to be signed.
-keyStoreDir : Directory of the keystore file.
-keyStoreName : Name of the keystore file.
-SignedDocDir : Direcory of the signed XML document generated.
-SignedDocName : Name of the signed XML document generated.
-keyAlias : Alias used in generating the keystore file.
-keyPassword : the key passord used in generating the keystore file.
-StorePassword : the key passord used in generating the keystore file.
-keystoreType : the keystore type used in generating the keystore file, e.g., PKCS12.
First the additional jar files are:
jsr105-api-1.0.1.jar, xmlsec-1.3.0.jar, commons-io-2.16.1.jar, xml-apis-1.4.01.jar, commons-logging-1.2.jar
Get them and add them to the additional libraries folder. (zip size is too large to upload here).
Before setting the paramaters and calling signDoc, check and request permission (PERMISSION_WRITE_EXTERNAL_STORAGE)
and add the following to the manifest file:
An example code:
The signed XML document should be found in the specified directory (DirInternal).
It can work in b4j also but I did not test it

Before setting the paramaters and calling signDoc, check and request permission (PERMISSION_WRITE_EXTERNAL_STORAGE)
and add the following to the manifest file:
XML:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>)An example code:
B4X:
Dim rp As RuntimePermissions
If rp.Check(rp.PERMISSION_WRITE_EXTERNAL_STORAGE) = False Then
rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
If Result = False Then
ToastMessageShow("Permission denied. The app cannot function without this permission.", True)
Activity.Finish
Return
End If
End If
Dim signXML1 As signXML
signXML1.keyAlias= "XXXXXXXXXXXXX"
signXML1.keyPassword="XXXXXXXXXXXXX"
signXML1.StorePassword="XXXXXXXXXXXXXX"
signXML1.keystoreType="XXXXXX"
File.Copy(File.DirAssets,"invoice.xml",File.DirInternal,"invoice.xml")
File.Copy(File.DirAssets,"keystore.p12",File.DirInternal,"keystore.p12")
signXML1.keyStoreDir=File.DirInternal
signXML1.keyStoreName="xxxxxx.p12"
signXML1.XmlDocDir= File.DirInternal
signXML1.XmlDocName="xxxxx.xml"
signXML1.SignedDocDir=File.DirInternal
signXML1.SignedDocName="signedxxxxxx.xml"
signXML1.SignDocIt can work in b4j also but I did not test it
