<pre>I think that there is a problem with generating "X-WOPI-Proof" header. It works
fine only for the 1st request. Then, it keeps returning the same value each
time. I managed to solve it by tweaking the SignProof method
(wsd/ProofKey.cpp):
std::string Proof::SignProof(const std::vectorchar>& proof) const
{
assert(m_pKey);
static Poco::Crypto::RSADigestEngine digestEngine(*m_pKey, "SHA256");
digestEngine.reset(); #this line fixed the issue
digestEngine.update(proof.data(), proof.size());
return BytesToBase64(digestEngine.signature());
}
I'm unsure if fully understand wopi proof key docs, so instead of creating a
merge request, I submit this bug.</pre>
