Mnemonic Sentences

7 declarations

typetype Entropy = ByteString

Random data used to create a mnemonic sentence. Use a good entropy source. You will get your coins stolen if you don't. You have been warned.

typetype Mnemonic = Text

Human-readable mnemonic sentence.

typetype Passphrase = Text

Optional passphrase for mnemnoic sentence.

typetype Seed = ByteString

Seed for a private key from a mnemonic sentence.

valuetoMnemonic :: Entropy -> Either String Mnemonic

Provide intial Entropy as a ByteString of length multiple of 4 bytes. Output a Mnemonic sentence.

valuefromMnemonic :: Mnemonic -> Either String Entropy

Revert toMnemonic. Do not use this to generate a Seed. Instead use mnemonicToSeed. This outputs the original Entropy used to generate a Mnemonic sentence.

valuemnemonicToSeed :: Passphrase -> Mnemonic -> Either String Seed

Get a 512-bit Seed from a Mnemonic sentence. Will validate checksum. Passphrase can be used to protect the Mnemonic. Use an empty string as Passphrase if none is required.
