func ArmoredPublicKey

func ArmoredPublicKey(entity *openpgp.Entity) (string, error)

func EntityFromSecring

func EntityFromSecring(keyId, keyFile string) (*openpgp.Entity, error)

EntityFromSecring returns the openpgp Entity from keyFile that matches keyId. If empty, keyFile defaults to osutil.SecretRingFile().

func GenerateNewSecRing

func GenerateNewSecRing(secRing string) (keyId string, err error)

GenerateNewSecRing creates a new secret ring file secRing, with a new GPG identity. It returns the public keyId of that identity. It returns an error if the file already exists.

func KeyIdFromRing

func KeyIdFromRing(secRing string) (keyId string, err error)

KeyIdFromRing returns the public keyId contained in the secret ring file secRing. It expects only one keyId in this secret ring and returns an error otherwise.

func NewEntity

func NewEntity() (*openpgp.Entity, error)

NewEntity returns a new OpenPGP entity.

func ParseArmoredPublicKey

func ParseArmoredPublicKey(r io.Reader) (shortKeyId, armoredKey string, err error)

ParseArmoredPublicKey tries to parse an armored public key from r, taking care to bound the amount it reads. The returned shortKeyId is 8 capital hex digits. The returned armoredKey is a copy of the contents read.

func VerifyPublicKeyFile

func VerifyPublicKeyFile(file, keyid string) (bool, error)

func WriteKeyRing

func WriteKeyRing(w io.Writer, el openpgp.EntityList) error

type CachingEntityFetcher

type CachingEntityFetcher struct {
	Fetcher EntityFetcher
	// contains filtered or unexported fields
}

func (*CachingEntityFetcher) FetchEntity

func (ce *CachingEntityFetcher) FetchEntity(keyId string) (*openpgp.Entity, error)

type EntityFetcher

type EntityFetcher interface {
	FetchEntity(keyId string) (*openpgp.Entity, error)
}

type FileEntityFetcher

type FileEntityFetcher struct {
	File string
}

func FlagEntityFetcher

func FlagEntityFetcher() *FileEntityFetcher

func (*FileEntityFetcher) FetchEntity

func (fe *FileEntityFetcher) FetchEntity(keyId string) (*openpgp.Entity, error)

type SignRequest

type SignRequest struct {
	UnsignedJSON string
	Fetcher      blob.Fetcher
	ServerMode   bool // if true, can't use pinentry or gpg-agent, etc.

	// Optional signature time. If zero, time.Now() is used.
	SignatureTime time.Time

	// Optional function to return an entity (including decrypting
	// the PrivateKey, if necessary)
	EntityFetcher EntityFetcher

	// SecretKeyringPath is only used if EntityFetcher is nil,
	// in which case SecretKeyringPath is used if non-empty.
	// As a final resort, we default to osutil.SecretRingFile().
	SecretKeyringPath string
}

func (*SignRequest) Sign

func (sr *SignRequest) Sign() (signedJSON string, err error)

type VerifyRequest

type VerifyRequest struct {
	CamliSigner     blob.Ref
	CamliSig        string
	PublicKeyPacket *packet.PublicKey

	// set if Verify() returns true:
	PayloadMap  map[string]interface{} // The JSON values from BPJ
	SignerKeyId string                 // e.g. "2931A67C26F5ABDA"

	Err error // last error encountered
	// contains filtered or unexported fields
}

See doc/json-signing/* for background and details on these variable names.

func NewVerificationRequest

func NewVerificationRequest(sjson string, fetcher blob.Fetcher) (vr *VerifyRequest)

func (*VerifyRequest) FindAndParsePublicKeyBlob

func (vr *VerifyRequest) FindAndParsePublicKeyBlob() bool

func (*VerifyRequest) ParsePayloadMap

func (vr *VerifyRequest) ParsePayloadMap() bool

func (*VerifyRequest) ParseSigMap

func (vr *VerifyRequest) ParseSigMap() bool

func (*VerifyRequest) Verify

func (vr *VerifyRequest) Verify() bool

TODO: turn this into (bool, os.Error) return, probably, or *Details, os.Error.

func (*VerifyRequest) VerifySignature

func (vr *VerifyRequest) VerifySignature() bool
