# The Ghidra application establishes the default SSLContext for all
# secure client connections based upon Java's default TLS protocol enablement.  
# Setting this property will restrict the enabled TLS protocol versions for 
# all secure network connections.  Specifying multiple protocols must be
# comma-separated (e.g., TLSv1.2,TLSv1.3).  See https://java.com/en/configure_crypto.html 
# for details on configuring Java's cryptographic algorithms.

# Force PKI server authentication of all HTTPS and Ghidra Server connections by

# Enable verbose logging for network SSL/TLS negotiations.
# This can be very useful when troubleshooting SSLHandshakeException failures which can 
# manifest with very cryptic messages.  All Ghidra Server communications rely on secure
# SSL/TLS connections.  This VMARG should only be uncommented while actively troubleshooting
# since it will log a significant amount of data.

# The following property will limit the number of processor cores that Ghidra

# The following property is a way to exactly specify the number of processor

# Settings directory used by the application to store application settings and data that persist

# are required to be absolute paths. The current user name may be incorporated into the settings
# directory's name if the settings directory lives outside of the user's home directory.  The
# settings directory will be selected based on the following rules, in order of precedence:
# 1. System.getProperty("application.settingsdir")/[user-]<application>/<application>_<version>
# 2. System.getenv("XDG_CONFIG_HOME")/[user-]<application>/<application>_<version>
# 3. A platform specific default location:

# directory lives outside of the user's home directory. The cache directory will be selected based
# on the following rules, in order of precedence
# 1. System.getProperty("application.cachedir")/[user-]<application>
