crypto.LedgerShowAddress() is a ledger specific function
and should takes acc address prefix instead of depending
on a sdk.Config singleton.
crypto/keys/mintkey:
- decryptPrivKey() return error instead of os.Exit()ing.
- encryptPrivKey() should panic instead of os.Exit() when
bcrypt.GenerateFromPassword() call fails so that the
caller is given a chance to recover().
crypto/keys:
- SignWithLedger() does not need to be method of
baseKeybase. Method receiver is unused.
- ledgerInfo objecta may be pointers, type switch
should handle both to avoid panics.
- keyringKeybase should not provide Update() at all.
More test cases are added to increase package crypto
and subpackages overall coverage.
