crypto/keyring: `Keybase` interface gives way to its successor: `Keyring`. `LegacyKeybase` interface is added in order to guarantee limited backward compatibility with the old `Keybase` interface for the sole purpose of migrating keys across the new keyring backends. The package no longer depends on the `github.com/types.Config` singleton. `SupportedAlgos` and `SupportedLedgerAlgos` methods have been removed. The keyring just fails when trying to perform an action with an unsupported algorithm. crypto/ subdirs reorganization: `crypto/keys/hd` was moved to `crypto/hd`, which now groups together all HD wallets related types and utilities. client/input: * Removal of unnecessary `GetCheckPassword`, `PrintPrefixed` functions. * `GetConfirmation`'s signature changed to take in a io.Writer for better integration with `cobra.Command` types. client/context: * In-memory keyring is allocated in the context when `--gen-only` flag is passed in. `GetFromFields` does no longer silently allocate a keyring, it takes one as argument.
