 ## From entropy to mnemonic secrets
 
-The value to be encoded as the master secret must be a multiple of 16 bits. This is typically a wallet entropy, but we do not restrict the usage in any way. The master secret is divided into N Shamir parts and M specifies how many of those parts do we need to reconstruct the master secret. We use GF(256) as the underlying field. We consider the master secret in a form which includes its own checksum:
