Android Question <DigestValue> and <SignatureValue>

[Angelo Messina]

this time I have a problem with writing digital files with the digital signature and
I asked you if you could give me some indication about how to get:
<SignedInfo><CanonicalizationMethod Algorithm = "http://www.w3.org/TR/2001/REC-xml-c14n-20010315" />
<SignatureMethod Algorithm = "http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" />
<Reference URI = "">
<Transforms>
<Transform Algorithm = "http://www.w3.org/2000/09/xmldsig#enveloped-signature" />
</ Transforms>
<DigestMethod Algorithm = "http://www.w3.org/2001/04/xmlenc#sha256" />
<DigestValue> xxxxxx </ DigestValue>
<SignedInfo> <SignatureValue> yyyyyyyy </ SignatureValue>

I have to get xxxxxx and yyyyyyyyy

thank you!

The question is not very clear. You can use MessageDigest from the Encryption library to calculate the signature: https://www.b4x.com/android/help/encryption.html#messagedigest
