• Bumped einherjar dependencies (auth, contracts, core, web) to v1.1.0 via go get + go mod tidy. No code or API changes.

v1.0.0

Initial release.

Signers and Verifiers

• Verifier interface — Verify(tokenString string) (*jwt.Token, error)
• Signer interface — extends Verifier; adds Sign(claims jwt.Claims) (string, error)
• NewHMACSigner(secret []byte) Signer — HMAC-SHA256 (HS256)
• NewRSASigner(privateKey *rsa.PrivateKey) Signer — RSA-SHA256 (RS256); public key derived from private
• NewRSASignerFromPEM(pemKey []byte) (Signer, error) — parses PKCS#8 or PKCS#1 PEM
• NewRSAPublicKeyVerifier(publicKey *rsa.PublicKey) Verifier — verify-only; use when the service never issues tokens
• NewRSAPublicKeyVerifierFromPEM(pemKey []byte) (Verifier, error) — parses PKIX or PKCS#1 PEM
• NewECSigner(privateKey *ecdsa.PrivateKey) Signer — ECDSA; algorithm auto-detected from curve (P-256→ES256, P-384→ES384, P-521→ES512)
• NewECSignerFromPEM(pemKey []byte) (Signer, error) — parses PKCS#8 PEM
• NewECPublicKeyVerifier(publicKey *ecdsa.PublicKey) Verifier — EC verify-only
• NewECPublicKeyVerifierFromPEM(pemKey []byte) (Verifier, error) — parses PKIX PEM
• All Verify implementations use jwt.WithJSONNumber() — preserves large int64 bitmasks through JSON round-trip

Token issuance

• TokenConfig struct — AccessTTL time.Duration, RefreshTTL time.Duration, Issuer string
• TokenPair struct — AccessToken string, RefreshToken string, ExpiresIn int64
• IssueTokenPair(signer, uid, customClaims, cfg) (TokenPair, error) — signs access + refresh pair; customClaims merged at top level of access token; refresh token carries only sub/iss/iat/exp/jti/fam

Token refresh

• Blacklist interface — IsRevoked(ctx, jti) (bool, error) + Revoke(ctx, jti, ttl) error; satisfied by cache-valkey via duck typing
• ErrTokenRevoked — sentinel error; use errors.Is(err, authjwt.ErrTokenRevoked) to detect replay attacks
• RefreshTokenPair(ctx, signer, refreshToken, bl, cfg, customClaims) (TokenPair, error) — validates token, checks blacklist, revokes old JTI, issues new pair; customClaims re-embedded in new access token

HTTP middleware

• AuthMiddleware(logger, verifier, publicPaths) func(http.Handler) http.Handler — verifies Bearer tokens; calls authmw.SetTokenData on success; routes 401 through httputil.Error; publicPaths support path.Match wildcards
