Functions

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 FactoryOpts

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

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 `yaml:"KeyStore"`
}

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

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?)
	Security     int               `json:"security" yaml:"Security"`
	Hash         string            `json:"hash" yaml:"Hash"`
	FileKeystore *FileKeystoreOpts `json:"filekeystore,omitempty" yaml:"FileKeyStore,omitempty"`
}

SwOpts contains options for the SWFactory
