Functions ¶

Types ¶

func GenPrivKey ¶

func GenPrivKey() *PrivKey

GenPrivKey generates a new ed25519 private key. It uses OS randomness in conjunction with the current global random seed in tendermint/libs/common to generate the private key.

func GenPrivKeyFromSecret ¶

func GenPrivKeyFromSecret(secret []byte) *PrivKey

GenPrivKeyFromSecret hashes the secret with SHA2, and uses that 32 byte output to create the private key. NOTE: secret should be the output of a KDF like bcrypt, if it's derived from user input.

func (*PrivKey) Bytes ¶

func (privKey *PrivKey) Bytes() []byte

Bytes returns the privkey byte format.

func (*PrivKey) Descriptor ¶

func (*PrivKey) Descriptor() ([]byte, []int)

func (*PrivKey) Equals ¶

func (privKey *PrivKey) Equals(other cryptotypes.LedgerPrivKey) bool

Equals - you probably don't need to use this. Runs in constant time based on length of the keys.

func (*PrivKey) GetKey ¶

func (m *PrivKey) GetKey() crypto_ed25519.PrivateKey

func (*PrivKey) Marshal ¶

func (m *PrivKey) Marshal() (dAtA []byte, err error)

func (PrivKey) MarshalAmino ¶

func (privKey PrivKey) MarshalAmino() ([]byte, error)

MarshalAmino overrides Amino binary marshalling.

func (PrivKey) MarshalAminoJSON ¶

func (privKey PrivKey) MarshalAminoJSON() ([]byte, error)

MarshalAminoJSON overrides Amino JSON marshalling.

func (*PrivKey) MarshalTo ¶

func (m *PrivKey) MarshalTo(dAtA []byte) (int, error)

func (*PrivKey) MarshalToSizedBuffer ¶

func (m *PrivKey) MarshalToSizedBuffer(dAtA []byte) (int, error)

func (*PrivKey) ProtoMessage ¶

func (*PrivKey) ProtoMessage()

func (*PrivKey) PubKey ¶

func (privKey *PrivKey) PubKey() cryptotypes.PubKey

PubKey gets the corresponding public key from the private key.

Panics if the private key is not initialized.

func (*PrivKey) Reset ¶

func (m *PrivKey) Reset()

func (*PrivKey) Sign ¶

func (privKey *PrivKey) Sign(msg []byte) ([]byte, error)

Sign produces a signature on the provided message. This assumes the privkey is wellformed in the golang format. The first 32 bytes should be random, corresponding to the normal ed25519 private key. The latter 32 bytes should be the compressed public key. If these conditions aren't met, Sign will panic or produce an incorrect signature.

func (*PrivKey) Size ¶

func (m *PrivKey) Size() (n int)

func (*PrivKey) String ¶

func (m *PrivKey) String() string

func (*PrivKey) Type ¶

func (privKey *PrivKey) Type() string

func (*PrivKey) Unmarshal ¶

func (m *PrivKey) Unmarshal(dAtA []byte) error

func (*PrivKey) UnmarshalAmino ¶

func (privKey *PrivKey) UnmarshalAmino(bz []byte) error

UnmarshalAmino overrides Amino binary marshalling.

func (*PrivKey) UnmarshalAminoJSON ¶

func (privKey *PrivKey) UnmarshalAminoJSON(bz []byte) error

UnmarshalAminoJSON overrides Amino JSON marshalling.

func (*PrivKey) XXX_DiscardUnknown ¶

func (m *PrivKey) XXX_DiscardUnknown()

func (*PrivKey) XXX_Marshal ¶

func (m *PrivKey) XXX_Marshal(b []byte, deterministic bool) ([]byte, error)

func (*PrivKey) XXX_Merge ¶

func (m *PrivKey) XXX_Merge(src proto.Message)

func (*PrivKey) XXX_Size ¶

func (m *PrivKey) XXX_Size() int

func (*PrivKey) XXX_Unmarshal ¶

func (m *PrivKey) XXX_Unmarshal(b []byte) error

type PubKey ¶

type PubKey struct {
	Key crypto_ed25519.PublicKey `protobuf:"bytes,1,opt,name=key,proto3,casttype=crypto/ed25519.PublicKey" json:"key,omitempty"`
}

PubKey defines a ed25519 public key Key is the compressed form of the pubkey. The first byte depends is a 0x02 byte if the y-coordinate is the lexicographically largest of the two associated with the x-coordinate. Otherwise the first byte is a 0x03. This prefix is followed with the x-coordinate.

func (*PubKey) Address ¶

func (pubKey *PubKey) Address() crypto.Address

Address is the SHA256-20 of the raw pubkey bytes.

func (*PubKey) Bytes ¶

func (pubKey *PubKey) Bytes() []byte

Bytes returns the PubKey byte format.

func (*PubKey) Descriptor ¶

func (*PubKey) Descriptor() ([]byte, []int)

func (*PubKey) Equals ¶

func (pubKey *PubKey) Equals(other cryptotypes.PubKey) bool

func (*PubKey) GetKey ¶

func (m *PubKey) GetKey() crypto_ed25519.PublicKey

func (*PubKey) Marshal ¶

func (m *PubKey) Marshal() (dAtA []byte, err error)

func (PubKey) MarshalAmino ¶

func (pubKey PubKey) MarshalAmino() ([]byte, error)
