Privacy, rights, and limits
Most processing is designed to run in the browser whenever possible, which makes the tool useful for quick personal or work files. For sensitive, production, or regulated material, test with a sample first and confirm the target platform's format, size, and quality requirements.
Common questions
What is the difference between hashing and encryption?
Hashing is a one-way digest. Encryption is reversible when the correct key is available.
When should I use AES, DES, MD5, or SHA?
AES is suitable for symmetric encryption. DES is not recommended for high-security use. MD5 is only for low-risk checks, while SHA-256 is better for secure digests.
How should I store encryption keys?
Do not put keys in front-end code, screenshots, or public repositories. Production systems should use a secure key-management service.
