)

const (
	// PluginFactoryName is the factory name for BCCSP plugins

Functions

func GetBCCSP

func GetBCCSP(name string) (bccsp.BCCSP, error)

GetBCCSP returns a BCCSP created according to the options passed in input.

func GetBCCSPFromOpts

func GetBCCSPFromOpts(config *FactoryOpts) (bccsp.BCCSP, error)

GetBCCSPFromOpts returns a BCCSP created according to the options passed in input.

func GetDefault

func GetDefault() bccsp.BCCSP

GetDefault returns a non-ephemeral (long-term) BCCSP

func InitFactories

func InitFactories(config *FactoryOpts) error

InitFactories must be called before using factory interfaces It is acceptable to call with config = nil, in which case some defaults will get used Error is returned only if defaultBCCSP cannot be found

Types

type BCCSPFactory

type BCCSPFactory interface {

	// Name returns the name of this factory
	Name() string

	// Get returns an instance of BCCSP using opts.
	Get(opts *FactoryOpts) (bccsp.BCCSP, error)
}

BCCSPFactory is used to get instances of the BCCSP interface. A Factory has name used to address it.

type DummyKeystoreOpts

type DummyKeystoreOpts struct{}

type FactoryOpts

type FactoryOpts struct {
	ProviderName string      `mapstructure:"default" json:"default" yaml:"Default"`
	SwOpts       *SwOpts     `mapstructure:"SW,omitempty" json:"SW,omitempty" yaml:"SwOpts"`
	PluginOpts   *PluginOpts `mapstructure:"PLUGIN,omitempty" json:"PLUGIN,omitempty" yaml:"PluginOpts"`
}

FactoryOpts holds configuration information used to initialize factory implementations

func GetDefaultOpts

func GetDefaultOpts() *FactoryOpts

GetDefaultOpts offers a default implementation for Opts returns a new instance every time

func (*FactoryOpts) FactoryName

func (o *FactoryOpts) FactoryName() string

FactoryName returns the name of the provider

type FileKeystoreOpts

type FileKeystoreOpts struct {
	KeyStorePath string `mapstructure:"keystore" yaml:"KeyStore"`
}

Pluggable Keystores, could add JKS, P12, etc..

type GMFactory

type GMFactory struct{}

GMFactory is the factory of the guomi-based BCCSP.

func (*GMFactory) Get

func (f *GMFactory) Get(config *FactoryOpts) (bccsp.BCCSP, error)

Get returns an instance of BCCSP using Opts.

func (*GMFactory) Name

func (f *GMFactory) Name() string

Name returns the name of this factory

type InmemKeystoreOpts

type InmemKeystoreOpts struct{}

InmemKeystoreOpts - empty, as there is no config for the in-memory keystore

type PluginFactory

type PluginFactory struct{}

PluginFactory is the factory for BCCSP plugins

func (*PluginFactory) Get

func (f *PluginFactory) Get(config *FactoryOpts) (bccsp.BCCSP, error)

Get returns an instance of BCCSP using Opts.

func (*PluginFactory) Name

func (f *PluginFactory) Name() string

Name returns the name of this factory

type PluginOpts

type PluginOpts struct {
	// Path to plugin library
	Library string
	// Config map for the plugin library
	Config map[string]interface{}
}

PluginOpts contains the options for the PluginFactory

type SWFactory

type SWFactory struct{}

SWFactory is the factory of the software-based BCCSP.

func (*SWFactory) Get

func (f *SWFactory) Get(config *FactoryOpts) (bccsp.BCCSP, error)

Get returns an instance of BCCSP using Opts.

func (*SWFactory) Name

func (f *SWFactory) Name() string

Name returns the name of this factory

type SwOpts

type SwOpts struct {
	// Default algorithms when not specified (Deprecated?)
	SecLevel   int    `mapstructure:"security" json:"security" yaml:"Security"`
	HashFamily string `mapstructure:"hash" json:"hash" yaml:"Hash"`

	// Keystore Options
	Ephemeral     bool               `mapstructure:"tempkeys,omitempty" json:"tempkeys,omitempty"`
