Error with verifier.verify

[calvinmetcalf]

ah that's the issue, browserify/parse-asn1#6 is the pull that fixes cert parsing which I need to rebase and merge

[calvinmetcalf]

sorry for taking so long to get back to you

• what format is the awsPublicCertificateRSA in? is the first line start with BEGIN and the last line with END ?

• what happends when you change your code to be

const verifier = crypto.createVerify('RSA-SHA256');
verifier.update(oraclize_doc, 'base64');
awsSignatureValid = verifier.verify(awsPublicCertificateRSA, awsSignature, 'base64');

• Can you provide the stack trace for the error?

The certificate is valid, correctly formatted with '-----BEGIN' and 'END'. (Working with crypto in node, and jsrsasign on browser).

Using the code you provided, I got:

TypeError: Cannot read property '2' of null

Note, this issue can be closed, as my workaround has been to just use the jsrsasign library on the browser-side.

not debating that it is correctly formatted, just wondering if the format is one we don't support, what is the full top line ?

No problem, here is exactly how it is formatted.
