Encrypt / Decrypt AES-256 is kept for interoperability and maintenance workflows where exact AES behavior matters.
This page is for controlled use cases such as migrating data, verifying compatibility, or maintaining a legacy process that still depends on a known AES-256 implementation.
Use carefully
Only use compatibility crypto utilities when you understand the mode, key handling, and storage implications. New systems should use reviewed libraries, strong key management, and explicit security boundaries rather than ad hoc utility pages.
Supporting visuals
Compatibility work needs explicit boundaries, not a silent copy of old behavior.
Crypto helpers should stay documented, limited in scope, and easy to audit.
