AI Analysis
●●SolidSlickNiche Gem
Local-only steganography with AES-256 encryption beats server-side tools on privacy.
Strengths
- •PBKDF2 with 100k iterations adds real brute-force resistance to the encryption layer.
- •Visual pixel bit demo educates users on how LSB manipulation actually works.
- •Zero network requests architecture guarantees files never leave the user's browser.
Weaknesses
- •LSB steganography is statistically detectable by dedicated steganalysis tools regardless of encryption.
- •Embedding large files bloats the PNG size significantly compared to standard attachments.
