ASP Classic - convert base64binary string to byte array

Question

I am trying to convert a base64binary string to a byte array in classic ASP. StrConv() doesn't exist in ASP.

My objective is to take the base64binary string received from a web service call, and write the binary format to a file.

thanks,
-m

When faced with a similar situation some time ago, I used MSXML to convert the data to a byte array before saving it to a file. You will need version 3 or higher.

To do this you would:

Load the data with MSXML
Set the node's dataType property to bin.base64
Read the binary data from the node using the nodeTypedValue property
To save the file you can use the ADODB.Stream component.

A few links on how the to this are below.
