Validate XML Signature

Hi,

I am trying to validate incoming XML signature to check the integrity of the message. Following is the example of XML Signature which contains the information of algorithms in transformation tags, applied to content (before applying Hash method) mentioned in Reference URI tag. After transformation, hashing will be done on the transformed content to create signature value using public key(certificate).

<ds:Signature xmlns:ds="www.w3.org/.../xmldsig

<ds:SignedInfo>

<ds:CanonicalizationMethod Algorithm="www.w3.org/.../xml-exc-c14n

<ds:SignatureMethod Algorithm="www.w3.org/.../xmldsig

<ds:Reference URI="#pfx3f1d777f-1644-ad18-6a15-68af4ed0a9a1">

<ds:Transforms>

<ds:Transform Algorithm="www.w3.org/.../xmldsig

<ds:Transform Algorithm="www.w3.org/.../xml-exc-c14n

</ds:Transforms>

<ds:DigestMethod Algorithm="www.w3.org/.../xmldsig

<ds:DigestValue>DigestValue</ds:DigestValue>

</ds:Reference>

</ds:SignedInfo>

<ds:SignatureValue>SignatureValue</ds:SignatureValue>

<ds:KeyInfo>

<ds:X509Data>

<ds:X509Certificate>Certificate</ds:X509Certificate>

</ds:X509Data>

</ds:KeyInfo>

</ds:Signature>

I am unable to apply algorithms for Canonicalization method and transformation (enveloped-signature, xml-exc-c14n#") on content. Is there any way to apply transformations in OpenEdge?

Or is there any other way available to validate the signature in OpenEdge?

OE version 11.4

Thanks in advance.
