0.2.0 #

  • Added a minimal ASN.1 DER reader (package:boring/asn1.dart) for decoding the application-specific payloads of X.509 extensions:
    • Asn1Reader, Asn1Value, Asn1Class, Asn1Tag, and Asn1Exception.
    • Decodes strings, integers, booleans, object identifiers, and nested constructed elements, including long-form lengths and context-specific tags.
  • Added X.509 v3 extension support to X509Certificate:
    • extensions enumerates every extension with its OID, short name, criticality, and raw DER payload.
    • getExtension(oid) and getExtensionString(oid) look up an extension by dotted-decimal OID, transparently unwrapping DER-encoded ASN.1 strings and falling back to raw UTF-8 payloads.
    • subjectAlternativeNames and issuerAlternativeNames decode GeneralName entries, with emailAddresses, dnsNames, and uris convenience getters.
    • keyUsage, extendedKeyUsage, isCertificateAuthority, and subjectKeyIdentifier.
  • Added X509Oid constants for standard X.509 extensions, Certificate Transparency SCTs, and all Sigstore Fulcio OIDC extensions (1.3.6.1.4.1.57264.1.*), plus KeyUsage bit constants.
  • Added a Project Wycheproof conformance test suite (tool/run_conformance_tests.sh) covering AEAD, Ed25519, ECDSA, RSA, HKDF, and HMAC.
  • Added GitHub Actions CI running formatting, analysis, unit tests, and the conformance suite.

0.1.0 #

  • Initial release of package:boring.
  • High-performance cryptography and PKI powered by BoringSSL with Dart Native Assets.
  • Isolated symbols with bssl_dart prefix to guarantee 100% collision-free execution alongside Flutter and Dart VM internal BoringSSL.
  • Cryptographic primitives:
    • CSPRNG (BoringRand.secureRandom)
    • Digests (BoringDigest: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, streaming DigestContext)
    • HMAC (BoringHmac: SHA-256, SHA-384, SHA-512, streaming HmacContext)
    • HKDF (BoringHkdf: extract, expand, deriveBits)
    • AEAD (BoringAead: AES-128-GCM, AES-256-GCM, ChaCha20-Poly1305, XChaCha20-Poly1305)
    • Ed25519 (BoringEd25519: keypair generation, sign, verify)
    • Asymmetric Keys (BoringPrivateKey, BoringPublicKey: RSA, ECDSA P-256/P-384/P-521, PKCS#8 & SPKI DER/PEM)
  • PKI & X.509:
    • Certificate parsing (X509Certificate: DER and PEM, metadata getters, public key extraction)
    • Chain verification (X509Verifier: trust store management, intermediate chain resolution, time-based verification)
