ZScaler issues inserting company certificate mid-transit of a TLS tunnel
# SSL Cert issues
Need to get the .crt file for ZScaler. Can be done with an OpenSSL command or by asking IT for a copy.
## Extracting the cert(?)
```
openssl x509 -inform DER -in /mnt/d/eset.cer -out ./ZscalerRootCertificate-2048-SHA256.crt
```
## Installing the cert
```
sudo cp ZscalerRootCertificate-2048-SHA256.crt /usr/local/share/ca-certificates/
sudo update-ca-certificates
```
