Re: Importing ECDSA public key from javascript/subtlecrypto

Hello Adam, Thanks for your reply. There are two issues with the pem-jwk package: 1) It's an npm-package and using browserify didn't seem to produce a usable file. 2) When you look into the code you see that it uses RSAPublicKey.encode, while I need ECDSA keys. I also looked into generating a crt from within PHP, but the standard is complex and I don't have the time nor skills at this time to build something like that myself.
