A 2nd script attempting to use a list of passwords against a gpg key (but I'm not sure if really guessing the gpg key password)

gistfile1.txt

#!/bin/bash

# File containing passwords to test
PASSWORD_FILE="password_combinationsZ2.txt"
# The key ID you want to test against
KEY_ID="1AB1E7A23BB73E4D" # Replace with your key ID (e.g., FA60B8E6A5A8D435)

if [ ! -f "$PASSWORD_FILE" ]; then
  echo "Password file not found: $PASSWORD_FILE"
  exit 1
fi

# Function to flush the GPG agent cache
flush_gpg_agent() {
  gpgconf --kill all
}

while IFS= read -r passphrase; do
  echo "Trying password: $passphrase"
  
  # Flush the GPG agent cache
  flush_gpg_agent

  # Test the passphrase with --passwd and --dry-run
  echo "$passphrase" | gpg --batch --pinentry-mode=loopback --passphrase-fd=0 --dry-run --passwd "$KEY_ID" --status-fd=1 2>/dev/null | grep -q "GOOD_PASSPHRASE"
  
  # Check if "GOOD_PASSPHRASE" was found in the output
  if [ $? -eq 0 ]; then
    echo "Success! Correct password is: $passphrase"
    exit 0
  fi
done < "$PASSWORD_FILE"

echo "No valid password found."
exit 1
