import "toolman.org/crypto/x509tools"

This package contains several x509-related helper functions not found in the standard library (albeit, perhaps they should be).

A non-trivial portion of this logic was take directly from the unexported side of the standard library's "crypto/x509" package -- therefore this package maintains the same copyright and license as the Go source code itself.

See the "LICENSE" file for more information.

Overview

Package x509tools provides various x509 related helper functions that are not found in the standard library.

Index

• func KeyUsageExtension(usage x509.KeyUsage) (pkix.Extension, error)
• func KeyUsageString(ku x509.KeyUsage) string
• type KeyUsage
  • func (ku KeyUsage) Extension() (pkix.Extension, error)
  • func (ku KeyUsage) String() string

Functions

func KeyUsageExtension

func KeyUsageExtension(usage x509.KeyUsage) (pkix.Extension, error)

KeyUsageExtension converts the provided x509.KeyUsage bitmask to a pkix.Extension representing those values. Note that the returned Extension alaways has its Critical flag set.

If a non-nil error is returned, it will come from an asn1 marshaling falure and the Extension value should be ignored.

func KeyUsageString

func KeyUsageString(ku x509.KeyUsage) string

KeyUsageString returns a string representation of the provided KeyUsage value. For KeyUsage values with multiple bit set, the resultant string will contain a pipe-separated list of strings.

Types

type KeyUsage

type KeyUsage x509.KeyUsage

KeyUsage is a convenience wrapper around x509.KeyUsage that provides the String and Extension methods.

func (KeyUsage) Extension

func (ku KeyUsage) Extension() (pkix.Extension, error)

Extension is a wrapper around this package's KeyUsageExtension function.

func (KeyUsage) String

func (ku KeyUsage) String() string

String implements the fmt.Stringer interface for type KeyUsage.
