Option to avoid line breaks in base64 (xmlSecBase64SetDefaultLineSize)

I had a problem where a signature breaks because of line breaks.
(this shouldn't fail, but I'm using an external service that I can't change)

The solution is found here:
https://www.aleksey.com/pipermail/xmlsec/2010/008921.html

For testing I added this in function PyXmlSec_Init (main.c):
xmlSecBase64SetDefaultLineSize(0);
and added this include
#include <xmlsec/base64.h>

This works for me.

Maybe this could be an option in python-xmlsec?

@r03 I like this suggestion. The linked PR adds a new function xmlsec.base64_line_size():

import xmlsec

# get the current setting
current_size = xmlsec.base64_default_line_size()

# set new size
xmlsec.base64_default_line_size(0)

It'd be great if you can try installing from the PR branch and confirm it works as intended!

Sorry. I’m no longer working on that project (it’s finished) and can’t really test. But your fix looks nice. Thanks!!
