[naviserver-devel] WebAuthn for NaviServer - ns_crypto::md with PEM as string

[Wolfgang W. <wol...@di...>]

Dear all,

I am currently writing a client for integrating webauthn into 
naviserver. It's a bunch of Javascript, a lot of encoding/decoding and 
some crypthography.

The various kinks are ironed out, and I can register users and verify 
webauthn.get responses.

Here's my question: I am using

::ns_crypto::md string -digest sha256 -verify ${req}.pem -signature 
$signature -binary $data_to_sign

to verify the signature of the data I get from the webauthn provider.

For this I currently write the .pem file to disk (after conversion from 
.der to .pem). Is it possible to circumvent this? We store the public 
key data in the database and it would be nice to use it as string.

Thanks for your input,

Wolfgang Winkler
