SOAP主体的XML签名

I'm implementing a client for a WS which requires soap:body to be signed. The application is written in Go so I would prefer to avoid linking to C.

The biggest issue is: how to calculate SHA256? What should be the input of digest algorithm? I assume that "/CJj9686ARgbV/YmDrr+1yhcaJuXu022cADK/M8efQs=" is a SHA256 result that is later signed. I tried many variations of canonicalized XML but none of them results in this hash.

Here is an example of correct SOAP message

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

    Finally, I found how to get all values.

    1. Canonicalize XML element defined in <SignedInfo><Reference>. In this case it's the <soap:Body> element. Canonicalization adds just soap namespace and adds closing tags. I'm generating these in Go and Go never generates self-closing tags.
    2. Calculate hash from a string representation of canonicalized <soap:Body> as it will be sent in a request.
    3. Add calculated digest into <DigestValue> of corresponding <Reference>.
    4. Canonicalize <SignedInfo> and calculate hash of it.
    5. Sign this hash and add value to <SignedValue>.

    I know that this is not a general approach but it should work for me. C14N is not necessary because Go can produce the same result if you pay attention to attributes order and manually add namespaces.
