xmlsec1- SignatureValue splitting across multiple lines - change setting to output as single line

[mueller68]

I am trying to sign an XML document for use in a program which is closed source and I cannot change how it is written.

Existing xml-signed files have all of the values for the on a single line.

When I generate a signed document using xmlsec1 on Fedora linux, it is generating the file, but the is split across 3 lines with the line feed at the end. I believe that manually changing it to a single line will invalidate it when it does the check, so I’m trying to generate it from xmlsec1 without the line feed. So I am trying to see if there is a setting or a way I can get it to output into a single line.

I am using RSA1024 Key Length

For example, it is outputting with these line feeds:

What I want is the output to look like:

What can I do to prevent it from splitting across multiple lines because of the length of the string?

I've added a command line option --base64-line-size in PR #706 and you can set it to some very large value (e.g. --base64-line-size 123456789) to disable line breaks.

It will be included in the next release or you can build the xmlsec library and command line tool from master after I merge the PR shortly.
