Overview

Package aip is a library for working with Author Identity Protocol (AIP) in Go

If you have any suggestions or comments, please feel free to open an issue on this GitHub repository!

var Prefix = "15PciHG22SNLQJXMoSUaWVi7WSqc7hCfva"

Prefix is the Bitcom prefix used by AIP

Functions

func ValidateTapes 

func ValidateTapes(tapes []bpu.Tape) (bool, error)

ValidateTapes validates the AIP signature for a given []bob.Tape

Example

ExampleValidateTapes example using ValidateTapes() 

// Get BOB data from a TX
bobValidData, err := bob.NewFromString(sampleValidBobTx)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}

// Get from tape
if valid, err := ValidateTapes(bobValidData.Out[0].Tape); valid {
	fmt.Print("AIP is valid")
} else if err != nil {
	fmt.Printf("AIP is invalid: %s", err.Error())
}

Output:
AIP is valid

Types

type Aip 

type Aip struct {
	Algorithm                 Algorithm `json:"algorithm"`                   // Known AIP algorithm type
	AlgorithmSigningComponent string    `json:"algorithm_signing_component"` // Changes based on the Algorithm
	Data                      []string  `json:"data"`                        // Data to be signed or validated
	Indices                   []int     `json:"indices,omitempty"`           // BOB indices
	Signature                 string    `json:"signature"`                   // AIP generated signature
}

Aip is an Author Identity Protocol object

func NewFromAllTapes added in v0.3.2 

func NewFromAllTapes(tapes []bpu.Tape) []*Aip

NewFromAllTapes will create all AIP objects from a []bob.Tape

func NewFromTape added in v0.0.10 

func NewFromTape(tape bpu.Tape) (a *Aip)

NewFromTape will create a new AIP object from a bob.Tape Using the FromTape() alone will prevent validation (data is needed via SetData to enable)

Example

ExampleNewFromTape example using NewFromTape() 

// Get BOB data from a TX
bobValidData, err := bob.NewFromString(sampleValidBobTx)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}

// Get from tape given the AIP index
a := NewFromTape(bobValidData.Out[0].Tape[2])

fmt.Printf("address: %s signature: %s", a.AlgorithmSigningComponent, a.Signature)

Output:
address: 134a6TXxzgQ9Az3w8BcvgdZyA5UqRL89da signature: H+lubfcz5Z2oG8B7HwmP8Z+tALP+KNOPgedo7UTXwW8LBpMkgCgatCdpvbtf7wZZQSIMz83emmAvVS4S3F5X1wo=

func NewFromTapes added in v0.0.12 

func NewFromTapes(tapes []bpu.Tape) (a *Aip)

NewFromTapes will create a new AIP object from a []bob.Tape Using the FromTapes() alone will prevent validation (data is needed via SetData to enable)

Example

ExampleNewFromTapes example using NewFromTapes() 

// Get BOB data from a TX
bobValidData, err := bob.NewFromString(sampleValidBobTx)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}

// Get from tape given the AIP index
a := NewFromTapes(bobValidData.Out[0].Tape)

fmt.Printf("address: %s signature: %s", a.AlgorithmSigningComponent, a.Signature)

Output:
address: 134a6TXxzgQ9Az3w8BcvgdZyA5UqRL89da signature: H+lubfcz5Z2oG8B7HwmP8Z+tALP+KNOPgedo7UTXwW8LBpMkgCgatCdpvbtf7wZZQSIMz83emmAvVS4S3F5X1wo=

func Sign added in v0.0.10 

func Sign(privateKey *ec.PrivateKey, algorithm Algorithm, message string) (a *Aip, err error)

Sign will provide an AIP signature for a given private key and message using the provided algorithm. It prepends an OP_RETURN to the payload

Example

ExampleSign example using Sign() 

a, err := Sign(examplePrivateKey, BitcoinECDSA, exampleMessage)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}
fmt.Printf("address: %s signature: %s", a.AlgorithmSigningComponent, a.Signature)

Output:
address: 1DfGxKmgL3ETwUdNnXLBueEvNpjcDGcKgK signature: INQwm/7FV7S5wzDf4L+HayG8PVhenwgeZ0T5QuNnVGbtSe+7L+Um7lxcrjsj7eMi3N4K1dAOqrVbkESkQfV7odc=
Example (Paymail)

ExampleSign_paymail example using Sign() 

a, err := Sign(examplePrivateKey, Paymail, exampleMessage)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}
fmt.Printf("address: %s signature: %s", a.AlgorithmSigningComponent, a.Signature)

Output:
address: 031b8c93100d35bd448f4646cc4678f278351b439b52b303ea31ec9edb5475e73f signature: INQwm/7FV7S5wzDf4L+HayG8PVhenwgeZ0T5QuNnVGbtSe+7L+Um7lxcrjsj7eMi3N4K1dAOqrVbkESkQfV7odc=

func SignBobOpReturnData added in v0.0.10 

func SignBobOpReturnData(privateKey *ec.PrivateKey, algorithm Algorithm, output bpu.Output) (*bpu.Output, *Aip, error)

func SignOpReturnData(privateKey *ec.PrivateKey, algorithm Algorithm,
	data [][]byte) (outData [][]byte, a *Aip, err error)

SignOpReturnData will append the given data and return a bt.Output

func (*Aip) FromTape 

func (a *Aip) FromTape(tape bpu.Tape)

FromTape takes a BOB Tape and returns an Aip data structure. Using the FromTape() alone will prevent validation (data is needed via SetData to enable)

func (*Aip) SetDataFromTapes added in v0.0.12 

func (a *Aip) SetDataFromTapes(tapes []bpu.Tape, instance int)

SetDataFromTapes sets the data the AIP signature is signing

func (*Aip) Validate 

func (a *Aip) Validate() (bool, error)

Validate returns true if the given AIP signature is valid for given data

Example

ExampleAip_Validate example using Validate() 

a, err := Sign(examplePrivateKey, BitcoinECDSA, exampleMessage)
if err != nil {
	fmt.Printf("error occurred: %s", err.Error())
	return
}

if valid, err := a.Validate(); valid {
	fmt.Printf("valid signature: %s", a.Signature)
} else if err != nil {
	fmt.Printf("signature validation failed: %s", err.Error())
}

Output:
valid signature: INQwm/7FV7S5wzDf4L+HayG8PVhenwgeZ0T5QuNnVGbtSe+7L+Um7lxcrjsj7eMi3N4K1dAOqrVbkESkQfV7odc=

type Algorithm 

type Algorithm string

Algorithm is an enum for the different possible signature algorithms 

const (
	BitcoinECDSA         Algorithm = "BITCOIN_ECDSA"        // Backwards compatible for BitcoinSignedMessage
	BitcoinSignedMessage Algorithm = "BitcoinSignedMessage" // New algo name
	Paymail              Algorithm = "paymail"              // Using "pubkey" as aip.Address
)
