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. While you're at it, what character set? UTF-8? UCS-16? ... Or was the string NUL-terminated, with the NUL included in the signature? Sadly there's lot of room for variation. And are you in fact in possession of the right signature key? Some folks might even return the signature in little-endian form, or for that matter the public key. -- Viktor.
