' help' shows a list of subcommands or help for one subcommand.

It supports interactive mode, when you are prompted for password as well as

non-interactive mode where passwords are supplied via a given password file.
|

Non-interactive mode is only meant for scripted use on test networks or known
|
||||
safe environments.
|
||||
|
||||
Make sure you remember the password you gave when creating a new account (with
|
||||
either new or import). Without it you are not able to unlock your account.
|
||||
|
||||
Note that exporting your key in unencrypted format is NOT supported.
|
||||
|
||||
Keys are stored under <DATADIR>/keystore.
|
||||
It is safe to transfer the entire directory or the individual keys therein
|
||||
between ethereum nodes by simply copying.
|
||||
Make sure you backup your keys regularly.
|
||||
|
||||
In order to use your account to send transactions, you need to unlock them using
|
||||
the '--unlock' option. The argument is a space separated list of addresses or
|
||||
indexes. If used non-interactively with a passwordfile, the file should contain
|
||||
the respective passwords one per line. If you unlock n accounts and the password
|
||||
file contains less than n entries, then the last password is meant to apply to

all remaining accounts.

The account is saved in the newest version in encrypted format, you are prompted

The keyfile is assumed to contain an unencrypted private key in hexadecimal format.

[![Build
|
||||
Status](https://travis-ci.org/ethereum/go-ethereum.png?branch=master)](https://travis-ci.org/ethereum/go-ethereum)
|
||||
|
||||
The common package contains the ethereum utility library.
|
||||
|
||||
# Installation
|
||||
|
||||
As a subdirectory the main go-ethereum repository, you get it with
|
||||
`go get github.com/ethereum/go-ethereum`.
|
||||
|
||||
# Usage
|
||||
|
||||
## RLP (Recursive Linear Prefix) Encoding
|
||||
|
||||
RLP Encoding is an encoding scheme used by the Ethereum project. It
|
||||
encodes any native value or list to a string.
|
||||
|
||||
More in depth information about the encoding scheme see the
|
||||
[Wiki](http://wiki.ethereum.org/index.php/RLP) article.
|
||||
|
||||
```go
|
||||
rlp := common.Encode("doge")
|
||||
fmt.Printf("%q\n", rlp) // => "\0x83dog"
|
||||
|
||||
rlp = common.Encode([]interface{}{"dog", "cat"})
|
||||
fmt.Printf("%q\n", rlp) // => "\0xc8\0x83dog\0x83cat"
|
||||
decoded := common.Decode(rlp)
|
||||
fmt.Println(decoded) // => ["dog" "cat"]
|
||||
```
|
||||
|
||||
## Patricia Trie
|
||||
|
||||
Patricie Tree is a merkle trie used by the Ethereum project.
|
||||

||||
found on the [Wiki](http://wiki.ethereum.org/index.php/Patricia_Tree).
|
||||
|
||||
The patricia trie uses a db as backend and could be anything as long as
|
||||
it satisfies the Database interface found in `common/db.go`.
|
||||
|
||||
```go
|
||||
db := NewDatabase()
|
||||
|
||||
// db, root
|
||||
trie := common.NewTrie(db, "")
|
||||
|
||||
trie.Put("puppy", "dog")
|
||||
trie.Put("horse", "stallion")
|
||||
trie.Put("do", "verb")
|
||||
trie.Put("doge", "coin")
|
||||
|
||||
// Look up the key "do" in the trie
|
||||
out := trie.Get("do")
|
||||
fmt.Println(out) // => verb
|
||||
|
||||
trie.Delete("puppy")
|
||||
```
|
||||
|
||||
The patricia trie, in combination with RLP, provides a robust,
|
||||
cryptographically authenticated data structure that can be used to store
|
||||
all (key, value) bindings.
|
||||
|
||||
```go
|
||||
// ... Create db/trie
|
||||
|
||||
// Note that RLP uses interface slices as list
|
||||
value := common.Encode([]interface{}{"one", 2, "three", []interface{}{42}})
|
||||
// Store the RLP encoded value of the list
|
||||
trie.Put("mykey", value)
|
||||
```
|
||||
|
||||
## Value
|
||||
|
||||
Value is a Generic Value which is used in combination with RLP data or
|
||||
`([])interface{}` structures. It may serve as a bridge between RLP data
|
||||
and actual real values and takes care of all the type checking and
|
||||
casting. Unlike Go's `reflect.Value` it does not panic if it's unable to
|
||||
cast to the requested value. It simple returns the base value of that
|
||||
type (e.g. `Slice()` returns []interface{}, `Uint()` return 0, etc).
|
||||
|
||||
### Creating a new Value
|
||||
|
||||
`NewEmptyValue()` returns a new \*Value with it's initial value set to a
|
||||
`[]interface{}`
|
||||
|
||||
`AppendList()` appends a list to the current value.
|
||||
|
||||
`Append(v)` appends the value (v) to the current value/list.
|
||||
|
||||
```go
|
||||
val := common.NewEmptyValue().Append(1).Append("2")
|
||||
val.AppendList().Append(3)
|
||||
```
|
||||
|
||||
### Retrieving values
|
||||
|
||||
`Get(i)` returns the `i` item in the list.
|
||||
|
||||
`Uint()` returns the value as an unsigned int64.
|
||||
|
||||
`Slice()` returns the value as a interface slice.
|
||||
|
||||
`Str()` returns the value as a string.
|
||||
|
||||
`Bytes()` returns the value as a byte slice.
|
||||
|
||||
`Len()` assumes current to be a slice and returns its length.
|
||||
|
||||
`Byte()` returns the value as a single byte.
|
||||
|
||||
```go
|
||||
val := common.NewValue([]interface{}{1,"2",[]interface{}{3}})
|
||||
val.Get(0).Uint() // => 1
|
||||
val.Get(1).Str() // => "2"
|
||||
s := val.Get(2) // => Value([]interface{}{3})
|
||||
s.Get(0).Uint() // => 3
|
||||
```
|
||||
|
||||
## Decoding
|
||||
|
||||
Decoding streams of RLP data is simplified
|
||||
|
||||
```go
|
||||
val := common.NewValueFromBytes(rlpData)
|
||||
val.Get(0).Uint()
|
||||
```
|
||||
|
||||
## Encoding
|
||||
|
||||
Encoding from Value to RLP is done with the `Encode` method. The
|
||||
underlying value can be anything RLP can encode (int, str, lists, bytes)
|
||||
|
||||
```go
|
||||
val := common.NewValue([]interface{}{1,"2",[]interface{}{3}})
|
||||
rlp := val.Encode()
|
||||
// Store the rlp data
|
||||
Store(rlp)
|
||||
```

libsecp256k1
|
||||
============
|
||||
|
||||
[![Build Status](https://travis-ci.org/bitcoin/secp256k1.svg?branch=master)](https://travis-ci.org/bitcoin/secp256k1)
|
||||
|
||||
Optimized C library for EC operations on curve secp256k1.
|
||||
|
||||
This library is a work in progress and is being used to research best practices. Use at your own risk.
|
||||
|
||||
Features:
|
||||
* secp256k1 ECDSA signing/verification and key generation.
|
||||
* Adding/multiplying private/public keys.
|
||||
* Serialization/parsing of private keys, public keys, signatures.
|
||||
* Constant time, constant memory access signing and pubkey generation.
|
||||
* Derandomized DSA (via RFC6979 or with a caller provided function.)
|
||||
* Very efficient implementation.
|
||||
|
||||
Implementation details
|
||||
----------------------
|
||||
|
||||
* General
|
||||
* No runtime heap allocation.
|
||||
* Extensive testing infrastructure.
|
||||
* Structured to facilitate review and analysis.
|
||||
* Intended to be portable to any system with a C89 compiler and uint64_t support.
|
||||
* Expose only higher level interfaces to minimize the API surface and improve application security. ("Be difficult to use insecurely.")
|
||||
* Field operations
|
||||
* Optimized implementation of arithmetic modulo the curve's field size (2^256 - 0x1000003D1).
|
||||
* Using 5 52-bit limbs (including hand-optimized assembly for x86_64, by Diederik Huys).
|
||||
* Using 10 26-bit limbs.
|
||||
* Field inverses and square roots using a sliding window over blocks of 1s (by Peter Dettman).
|
||||
* Scalar operations
|
||||
* Optimized implementation without data-dependent branches of arithmetic modulo the curve's order.
|
||||
* Using 4 64-bit limbs (relying on __int128 support in the compiler).
|
||||
* Using 8 32-bit limbs.
|
||||
* Group operations
|
||||
* Point addition formula specifically simplified for the curve equation (y^2 = x^3 + 7).
|
||||
* Use addition between points in Jacobian and affine coordinates where possible.
|
||||
* Use a unified addition/doubling formula where necessary to avoid data-dependent branches.
|
||||
* Point/x comparison without a field inversion by comparison in the Jacobian coordinate space.
|
||||
* Point multiplication for verification (a*P + b*G).
|
||||
* Use wNAF notation for point multiplicands.
|
||||
* Use a much larger window for multiples of G, using precomputed multiples.
|
||||
* Use Shamir's trick to do the multiplication with the public key and the generator simultaneously.
|
||||
* Optionally (off by default) use secp256k1's efficiently-computable endomorphism to split the P multiplicand into 2 half-sized ones.
|
||||
* Point multiplication for signing
|
||||
* Use a precomputed table of multiples of powers of 16 multiplied with the generator, so general multiplication becomes a series of additions.
|
||||
* Access the table with branch-free conditional moves so memory access is uniform.
|
||||
* No data-dependent branches
|
||||
* The precomputed tables add and eventually subtract points for which no known scalar (private key) is known, preventing even an attacker with control over the private key used to control the data internally.
