# Check if the input directory exists
if [ ! -d "$input_dir" ]; then
    echo "Error: Directory '$input_dir' does not exist."
    exit 1

# Compute the hash

# Print the hash
echo "SHA-256 Hash: $hash"

# Write the hash to the output file
echo "$hash" > "$output_file"

echo "Hash has been written to '$output_file'"
