+Pre-encoded steganography samples for testing the **Agent tab's Exhaustive Mode** and other decoder tools without having to encode files yourself.
+
+All new examples (Plinian divider series) encode the secret message:

+        roughly the size of a walnut, making it one of the least intelligent
+        dinosaurs relative to its body size.</p>

+(to write), is the practice of concealing messages within other non-secret data.
+
+## Ancient Origins
+
+The earliest recorded use of steganography dates back to **440 BC**, when
+Histiaeus shaved a slave's head, tattooed a message on his scalp, and waited
+for the hair to regrow before sending him as a messenger.
+
+<!-- base64:4oqw4oCiLeKAouKcp+KAoi3igKIt4qaRL0xcTy9WXEUvXFAvTFxJL05cWS/ippIt4oCiLeKAouKcp+KAoi3igKLiirE= -->
+
+## Digital Era
+
+Modern digital steganography encompasses a wide range of techniques:
+
+| Technique | Medium | Capacity | Stealth |
+|-----------|--------|----------|---------|
+| LSB Embedding | Images | High | Medium |
+| DCT Domain | JPEG | Medium | High |
+| Whitespace | Text | Low | High |
+| Zero-Width | Text | Low | Very High |
+| Audio LSB | Audio | Medium | High |
+| Metadata | Any | Low | Medium |
+
+## Tools
+
+**ST3GG (STEGOSAURUS WRECKS)** is an advanced steganography toolkit supporting
+15 channel presets, 8 bit depths, and 4 encoding strategies.

+\begin{abstract}
+This report presents a comparative analysis of ornithischian dinosaur specimens,
+focusing on body mass, encephalization quotient, and defensive adaptations.
+The Stegosaurus remains one of the most distinctive members of this clade.
+\end{abstract}
+
+\section{Introduction}
+
+The Ornithischia (``bird-hipped'' dinosaurs) represent one of the two major
+clades of dinosaurs, characterized by a pubis bone that points backward.
+This clade includes many well-known species including Stegosaurus,
+Triceratops, and Ankylosaurus.

+\end{tabular}
+\end{table}
+
+\section{Encephalization Quotient}
+
+The encephalization quotient (EQ) provides a measure of relative brain size:
+\begin{equation}
+EQ = \frac{E_{actual}}{E_{expected}} = \frac{E_{actual}}{0.12 \cdot M^{0.67}}
+\end{equation}
+where $E_{actual}$ is the actual brain mass and $M$ is body mass in kilograms.
+
+\section{Conclusion}
+
+Ornithischian dinosaurs show remarkable diversity in defensive adaptations,
+from the plates and spikes of Stegosaurus to the armored shell of Ankylosaurus
+and the horned frill of Triceratops.

+How to Identify Steganography        
+==============================   		  	
+ 	 	 			
+Steganography is the practice of hiding secret information within 		 	   
+ordinary, non-secret data or physical objects. Unlike cryptography, 		 	  	
+which makes data unreadable, steganography conceals the very 			 	  
+existence of the secret message. 		  	 	
+ 			  		
+Common techniques include: 			    
+- Least Significant Bit (LSB) embedding in images 		    	
+- Hiding data in audio frequency spectrums 		   		
+- Using invisible Unicode characters in text 		  	 	
+- Appending data after file end markers  	     
+- Encoding in metadata fields 		 	   
+ 		 	  	
+Detection methods include statistical analysis, visual inspection 		  	  
+of bit planes, frequency domain analysis, and file structure 		  	 	
+examination. Tools like ST3GG can automate this process. 			  		
+  	     
+The word steganography comes from the Greek words 'steganos' 			  		
+(meaning covered or hidden) and 'graphein' (meaning to write). 		  	 	
+ 		   		
+In the digital age, steganography has found applications in 			  	 
+digital watermarking, covert communication, and CTF challenges. 		  	 	
+ 			 	  
+Always remember: just because you can't see it doesn't mean 			  		
+it's not there. Hidden in plain sight is the ultimate disguise.

+approximately 155 to 150 million years ago. It is best known for its distinctive row of large,
+bony plates along its back and the sharp spikes on its tail, known as the thagomizer.
+
+Despite its massive size, the Stegosaurus had a remarkably small brain, roughly the size of a
+walnut. This has led to much speculation about how such a large animal could function with such
+limited cognitive capacity.
+
+The name "Stegosaurus" means "roof lizard" or "covered lizard," referring to the plates on its
+back, which were once thought to lie flat like roof tiles. Modern research suggests these plates
+were used for thermoregulation and display rather than defense.
