Download the certificate from the browser
The certificate is in PEM format, a human readable format (base64) but also sometimes with CRLF line endings

Convert the certificate to a DER format (binary)

openssl x509 -in certificate.pem -out certificate.der -outform DER

Run sha256sum on the DER file
```
sha256sum certificate.der
```
Compare the hash with the one from the browser
Now the public key (which is inside the certificate)

Extract the public key from the certificate

openssl x509 -in certificate.der -pubkey -noout | openssl enc -base64 -d > publickey.der

Run sha256sum on the public key
```
sha256sum publickey.der
```
Compare the hash with the one from the browser
