certificate base64/hex code doesn't contain the private key error #64

Mounika80244 commented 3 years ago

I got the certificate from the token as a hex code ,so i need to use this certificate to sign a pdf in back end (.net C#). but I got error private key is missing. I have a doubt that always certificate from the token does not has private key or I made mistake somewhere else . Additional information: I got the details of the certificate from its hex code , but while signing only its showing No private key error I am using hwcrypto.js for getting certificate from USB token.

Certificates don't contain private keys but public keys, by design. Use the sign() method to sign.

@martinpaljak (Use the sign() method to sign.) I need to add signature to a pdf .here sign() method returns hex value of signature only.
