What file is needed to decrypt HTTPS?

Explanation:
Decrypting HTTPS in Wireshark requires the TLS session keys that were used to encrypt the traffic. Those keys are written by the client into a log file when TLS key logging is enabled. The standard file name/browser-provided path for this log is SSLKEYLOGFILE, which you point to via an environment variable so the browser can write the keys there. Wireshark can read this key log to derive the symmetric encryption keys and decrypt the TLS records, letting you view the HTTPS payload. The other suggested file names aren’t standard or supported for TLS key logging, so they won’t enable decryption.
