Mnemonic is a Go library which which generates mnemonics, which is a way of representing a large randomly-generated number as a sequence of words. A mnemonic gives us a convenient way to store this number, these words then may be used to create a seed. For example we could represent a 128 bit number as the following sequence of words:
"window pig filter walk eye damage arena turtle loyal lobster live act"
The greater the number the larger the sequence of words will be, a 256 bit number would generate a sequence of 24 words.
$ go get github.com/umahmood/mnemonic
package main
import (
"fmt"
"github.com/umahmood/mnemonic"
)
func main() {
m, err := mnemonic.New(mnemonic.DefaultConfig) // default 128 bits
if err != nil {
// ...
}
words, err := m.Words()
if err != nil {
// ...
}
fmt.Println(words)
}
Output:
[wild cause filter walk eye damage arena turtle loyal lobster live add]
Specifying a non-default config.:
m, err := mnemonic.New(mnemonic.Config{
Bits: 256, // must be a multiple of 32
})
You can specify a passphrase which will be used in generating a seed:
m, err := mnemonic.New(mnemonic.Config{
Bits: 256,
Passphrase: "To the moon!",
})
