Missing certificate chain and invalid JSON is produced with a dangling comma

[manuelbua]

I encountered an error while parsing the JSON produced by tls-scan and pinpointed it to a case where the certificate chain is missing from the JSON output and a dangling comma is left before closing the JSON object.

{ "host": "18.236.255.249", "ip": "18.236.255.249", "port": 443, "elapsedTime": 571, "tlsVersion": "TLSv1.2", "cipher": "ADH-AES256-SHA          SSLv3 Kx=DH       Au=None Enc=AES(256)  Mac=SHA1", "tempPublicKeyAlg": "DH", "tempPublicKeySize": 2048, "secureRenego": true, "compression": "NONE", "expansion": "NONE", "sessionLifetimeHint": 300, "x509ChainDepth": -1, "verifyCertResult": true, "verifyHostResult": false, "ocspStapled": false, }

To reproduce what i'm seeing you can try the following:

echo '18.236.255.249' | tls-scan | jq
parse error: Expected another key-value pair at line 1, column 441
