A stable Rust library for hiding and extracting secret messages within images using steganography.
Steganography is a Rust library that allows developers to hide and extract secret messages within image files using steganography techniques. It solves the problem of covert data transmission by embedding information in the alpha channel of images, making it invisible to casual observers. The library provides tools for encoding messages into images and decoding them back, ensuring data integrity and simplicity.
Rust developers working on security, privacy, or multimedia applications that require hidden data storage or transmission, such as in digital watermarking or secure messaging tools.
Developers choose this library for its stable Rust implementation, straightforward API focused on alpha channel manipulation, and efficiency in handling image-based steganography without external dependencies.

Specifically designed for embedding data in the alpha channel, preserving visual integrity by leveraging transparency changes, as demonstrated in the encode_alpha() and decode_alpha() methods in the README examples.
Offers clear Encoder and Decoder structs with straightforward methods, making integration easy, evidenced by the concise code snippets for encoding and decoding messages.
Built in Rust, ensuring memory safety and efficient image processing, supported by the use of Cargo for dependency management and Rust's standard libraries.
Includes practical examples like example_encode and example_decode, accelerating development by providing ready-to-run code that demonstrates core functionality.
Only supports steganography via the alpha channel, restricting use to image formats with transparency and lacking alternative data hiding methods for broader applications.
The library lacks advanced error recovery, as seen in the decode example where manual filtering of alpha values is required, which could lead to data loss or corruption if not handled carefully.
Focuses solely on data hiding without encryption, meaning hidden messages are vulnerable to extraction if the steganography technique is discovered, limiting use in high-security scenarios.
