dartage 0.2.0

Pure Dart implementation of the age v1 file format with native and extensible recipients, passphrases, post-quantum hybrids, and streaming.

Changelog

0.2.0

• Replaced the mutable string-based API with AgeRecipient, AgeIdentity, immutable AgeStanza, and typed native key classes.
• Added scrypt, ML-KEM-768 + X25519, P-256 tag, and ML-KEM-768 + P-256 tag recipients.
• Added bounded streaming encryption, decryption, and ASCII armor while keeping buffer convenience methods on the same pipeline.
• Added configurable header and scrypt resource limits and reorganized public error codes.
• Pinned and enabled the complete C2SP CCTV age corpus and expanded age-encryption 0.3.0 interoperability coverage.
• Added 0.1.x migration and security documentation.

0.1.1

• Patch release to verify automated pub.dev publishing from GitHub Actions using OIDC. There are no API or runtime behavior changes.

0.1.0

• Initial extraction from the dotweave CLI, where this code has been in production use.
• age v1 encryption and decryption with X25519 recipients, ASCII armor, identity/recipient key handling, and STREAM payload framing.
• scrypt (passphrase) recipients are explicitly rejected rather than partially handled.
• Verified against a 30-vector fixture corpus and, in the tagged interop suite, against the reference age-encryption npm implementation.

Initial public release. The API is expected to change before 1.0.
