flutter_eddsa 0.0.9

Flutter FFI plugin for Ed25519 digital signatures and X25519 Diffie-Hellman key exchange. High-performance Curve25519 cryptography via native C.

0.0.9

• Rewrote example app: step-by-step interactive demo covering key generation, Ed25519 signing, signature verification (including tamper detection), and X25519 Diffie-Hellman key exchange. All key and signature values are selectable and copyable.
• Added educational "color metaphor" page showing how DH key exchange works visually, accessible via the info button in the demo app.
• Added pub.dev version and pub points badges to README.
• Fixed installation snippet version constraint in README.

0.0.5

• Removed EddsaUtils.bytesFromString and EddsaUtils.stringFromBytes — not needed for cryptographic operations. Use dart:convert's utf8.encode/utf8.decode for text encoding.

0.0.4

• Relicensed from GPL-3.0 to MIT.

0.0.3

• Fixed license.

0.0.2

• Improved README: added Diffie-Hellman concept explanation with ASCII diagram and KDF note.
• Replaced example app with a focused Diffie-Hellman demo for pub.dev Example tab.

0.0.1

• Initial release.
• Ed25519 digital signatures: key derivation, signing, and verification.
• X25519 Diffie-Hellman key exchange.
• Ed25519 ↔ X25519 key conversion for both public and secret keys.
• Cryptographically secure random key generation via Random.secure().
• Native FFI implementation — no platform-channel overhead.
• Supports Android, iOS, macOS, Linux, and Windows.
