GlideDigest not working to calculate MD5Hash

[kailashthiyagar]

Hi all,

I m using GlideDigest to caclulate MD5hash in my scoped application.. i m in Istanbul release. Here is the code which i m using to calculate MD5Hash.. It generates different value for MD5Hash for my file. Please help me to understand what i m doing wrong over here.

var attachmentSysid='';
var ga=new GlideRecord('sys_attachment');
ga.addQuery('table_sys_id',current.sys_id);
ga.query();
while(ga.next()){
attachmentSysid=ga.sys_id;
}
var inputStream = new GlideSysAttachment().getContentStream(attachmentSysid);
var digest = new GlideDigest();
var test=digest.getMD5Base64FromInputStream(inputStream);
gs.addInfoMessage(test);

This is the link i have referred

https://developer.servicenow.com/app.do#!/api_doc?v=jakarta&id=c_GlideDigestScopedAPI

And earlier i tried with GlideCheckSum but since it needs to be whitelisted in order for it to be used and also it will work only in scoped application, i happened to go with this approach.

Hi Kailash,

Can you add the message marked in bold? Let me know what results you get for both the gs.addInfo

1. var attachmentSysid='';  
2. var ga=new GlideRecord('sys_attachment');  
3. ga.addQuery('table_sys_id',current.sys_id);  
4. ga.query();  
5.  
6. while(ga.next()){  
7. attachmentSysid=ga.sys_id;  
8. }  
9.   gs.addInfoMessage('attachmentSysid is --------------'+attachmentSysid);
10. var inputStream = new GlideSysAttachment().getContentStream(attachmentSysid);  
11. var digest = new GlideDigest();  
12. var test=digest.getMD5Base64FromInputStream(inputStream);  
13. gs.addInfoMessage(test);

This is what i have observed.

attachmentSysid gives the sys id of the record in the "sys_attachment" table and it has the file which we attached.

I attached the file in one of the online site, it gives me the expected MD5 value. But through this method, i m getting different MD5Hash value..

If you would like to try it in my instance, here is the information

ServiceNow

UserID : admin

Password :

Table : MD5Hash. And you can check the assoiciated BusinessRule for that

Hi Kailash,

What is the expected MD5 value and for which file?
