Steghide features and specs

• Open-Source
  Steghide is open-source software, meaning its source code is freely available for inspection, modification, and redistribution. This transparency allows users to verify the security and functionality of the application, contributing to community trust and security auditing.
• Wide Range of File Support
  It supports a variety of carriers for embedding data, including BMP, JPEG, WAV, and AU files, which provides flexibility in selecting the appropriate file type for concealing information, enhancing usability.
• Data Encryption
  Steghide encrypts the hidden data with a passphrase using the Rijndael AES algorithm. This adds an additional layer of security, making it more difficult for unauthorized parties to access the hidden content.
• Compression
  The software includes built-in data compression, which can reduce the size of the data to be hidden, potentially allowing larger amounts of data to fit within a carrier file without noticeably affecting its size.
• Embedding Robustness
  Steghide uses statistical methods to detect parts of the medium that can be altered without being noticed by the human senses, which improves the robustness and undetectability of the hidden data.

Possible disadvantages of Steghide

• Limited to Command Line Interface
  Steghide primarily operates via a command-line interface, which can be a barrier for users who are not comfortable with text-based interactions and prefer graphical user interfaces for better usability.
• Lack of Active Development
  The project has not seen recent updates, which may mean it lacks newer features or optimizations and may have unresolved bugs or vulnerabilities, potentially affecting its security and functionality in modern systems.
• Specific Use Case
  Being specialized for steganography, Steghide may not support broader cryptographic needs that users might have, necessitating the use of additional software for tasks outside data hiding.
• File Type Limitations
  Despite supporting several file types, the limitation to BMP, JPEG, WAV, and AU files can be restrictive. Users wanting to use other file formats for data hiding might need to find other tools or convert files, which can add steps to their workflow.

AWS Lambda features and specs

• Scalability
  AWS Lambda automatically scales your application by running your code in response to each trigger. This means no manual intervention is required to handle varying levels of traffic.
• Cost-effectiveness
  You only pay for the compute time you consume. Billing is metered in increments of 100 milliseconds and you are not charged when your code is not running.
• Reduced Operations Overhead
  AWS Lambda abstracts the infrastructure management layer, so there is no need to manage or provision servers. This allows you to focus more on writing code for your applications.
• Flexibility
  Supports multiple programming languages such as Python, Node.js, Ruby, Java, Go, and .NET, which allows you to use the language you are most comfortable with.
• Integration with Other AWS Services
  Seamlessly integrates with many other AWS services such as S3, DynamoDB, RDS, SNS, and more, making it versatile and highly functional.
• Automatic Scaling and Load Balancing
  Handles thousands of concurrent requests without managing the scaling yourself, making it suitable for applications requiring high availability and reliability.

Possible disadvantages of AWS Lambda

• Cold Start Latency
  The first request to a Lambda function after it has been idle for a certain period can take longer to execute. This is referred to as a 'cold start' and can impact performance.
• Resource Limits
  Lambda has defined limits, such as a maximum execution timeout of 15 minutes, memory allocation ranging from 128 MB to 10,240 MB, and temporary storage up to 512 MB.
• Vendor Lock-in
  Using AWS Lambda ties you into the AWS ecosystem, making it difficult to migrate to another cloud provider or an on-premises solution without significant modifications to your application.
• Complexity of Debugging
  Debugging and monitoring distributed, serverless applications can be more complex compared to traditional applications due to the lack of direct access to the underlying infrastructure.
• Cold Start Issues with VPC
  When Lambda functions are configured to access resources within a Virtual Private Cloud (VPC), the cold start latency can be exacerbated due to additional VPC networking overhead.
• Limited Execution Control
  AWS Lambda is designed for stateless, short-running tasks and may not be suitable for long-running processes or tasks requiring complex orchestration.
