[openssl-users] Verifying RSA-SHA1 signature?

[Nikolay Kudryavtsev]

Good question!

The canonical representation is just a single string of data. I've tried 
asking that third party whether they have any line endings at the end 
when they sign it, but received no usable answer. So the most probable 
is no line endings. I've tried all 3 options, gonna try again just in case.
