Package doh implements client operations for DoH (DNS over HTTPS) lookups. It implements looking up the following records:

• A

• AAAA

• CNAME

• MX

• NS

• TXT

• SRV

• SOA

• PTR

Package credentials provides types for retrieving credentials from credentials sources.

This package implements a functionality of managing the registration, marshaling, and unmarshaling of encoded types. It helps when types are sent over a ttrpc/GRPC API and marshaled as a protobuf Any.

This Package provides facilities for running metamorphic, property-based testing. By running logically equivalent operations with different conditions, metamorphic tests can identify bugs without requiring an oracle.

This package provides a HTTP client functionality that can be used across various Sakura Cloud APIs (IaaS, ObjectStorage, PHY, etc.).

Package token is variant of the stdlib package token with types FileSet and Token removed.

This package provides an interface for implementing milter mail filters for Go.

Package httpcache provides a http.RoundTripper implementation that works as a mostly RFC 7234 compliant cache for HTTP responses. It is only suitable for use as a "private" cache (i.e. for a web-browser or an API-client and not for a shared proxy).

This package provides a partial Go implementation of the Remote Call Procedure libraries, presented in @urlhttp://pubs.opengroup.org/onlinepubs/9629399/,CDE 1.1: Remote Procedure Call.

Package manager provides utilities to upload and download objects from S3 concurrently. Helpful for when working with large objects.

This package providies itegration tests module for k8s.io/kube-openapi.

This package contains several lexers and parsers written in Go.

This package provides packet processing capabilities for Go.

certmagic provides API for TLS Automation with full control over almost every aspect of the system.

Main features:

• Fully automated certificate management including issuance and renewal, with support for certificate revocation. Also works in conjunction with your own certificates.

• Wildcard certificates.

• One-line, fully managed HTTPS servers, with HTTP->HTTPS redirects.

• Multiple issuers supported: get certificates from multiple sources/CAs for redundancy and resiliency.

• Solves all 3 common ACME challenges: HTTP, TLS-ALPN, and DNS (and capable of others.)

• Robust error handling:

  • Challenges are randomized to avoid accidental dependence and rotated to overcome certain network blockages.

  • Robust retries for up to 30 days.

  • Exponential backoff with carefully-tuned intervals.

  • Retries with optional test/staging CA endpoint instead of production, to avoid rate limits.

• All libdns DNS providers work out-of-the-box.

• Pluggable storage backends (default: file system) and key sources.

• Automatic OCSP stapling.

• Distributed solving of all challenges (works behind load balancers.)

• Supports on-demand issuance of certificates.

• Optional event hooks for observation.

• One-time private keys by default (new key for each cert) to discourage pinning and reduce scope of key compromise.

• Works with any certificate authority (CA) compliant with the ACME specification RFC 8555.

• Must-Staple (optional; not default.)

• Full support for draft-ietf-acme-ari (ACME Renewal Information; ARI) extension.

GoBGP is an BGP implementation.

This package provides a Go language implementation of the QUIC network protocol.

This package provides a Go SDK based on the official APIs of Alibaba Cloud OSS.

ACMEz is a lightweight, fully-compliant RFC 8555 (ACME) implementation, that provides an API for getting certificates. ACMEz is suitable for large-scale enterprise deployments. It also supports common IETF-standardized ACME extensions.

This module has two primary packages:

• acmez is a high-level wrapper for getting certificates. It implements the ACME order flow described in RFC 8555 including challenge solving using pluggable solvers.

• acme is a low-level RFC 8555 implementation that provides the fundamental ACME operations, mainly useful if you have advanced or niche requirements.

Main features:

• Go API that thoroughly documented with spec citations.

• Structured error values (problems as defined in RFC 7807.)

• Smart retries (resilient against network and server hiccups.)

• Challenge plasticity (randomized challenges, and will retry others if one fails.)

• Context cancellation (suitable for high-frequency config changes or reloads.)

• Highly flexible and customizable.

• External Account Binding (EAB) support.

• Tested with numerous ACME CAs (more than just Let's Encrypt.)

• Implements niche aspects of RFC 8555 (such as alt cert chains and account key rollover.)

• Efficient solving of large SAN lists (e.g. for slow DNS record propagation.)

• Utility functions for solving challenges: device attestation challenges (draft-acme-device-attest-02), RFC 8737 (tls-alpn-01 challenge), RFC 8823 (email-reply-00 challenge; S/MIME.)

• ACME Renewal Information (ARI) support (draft-ietf-acme-ari-03.)

Package smithyotelmetrics implements a Smithy client metrics adapter for the OTEL Go SDK.

Package websocket implements the @urlhttps://rfc-editor.org/rfc/rfc6455.html,RFC 6455 WebSocket protocol.

This package provides a a drop-in replacement to github.com/pkg/errors and Go's standard errors package. It also provides of error objects, in ways suitable for distributed systems with mixed-version software compatibility.

Package sqs provides the API client, operations, and parameter types for Amazon Simple Queue Service.

Package kinesis implements a batch producer built on top of the official AWS SDK.

The dnsutils package provides a Go function to return a map of Service Records (SRV) in the order they should be used for a given service, protocol and name. The order is determined by the records' priority and randomized selection based on their relative weighting. This package is useful for network applications that require accessing services using SRV records.
