It will decrypt the keyJSON with the given passphrase and on successful decryption it will encrypt the key with the given newPassphrase and store it in the keystore. Example (the address in question has privkey `11...11`): {"jsonrpc":"2.0","method":"clef_import","params":[{"address":"19e7e376e7c213b7e7e7e46cc70a5dd086daff2a","crypto":{"cipher":"aes-128-ctr","ciphertext":"33e4cd3756091d037862bb7295e9552424a391a6e003272180a455ca2a9fb332","cipherparams":{"iv":"b54b263e8f89c42bb219b6279fba5cce"},"kdf":"scrypt","kdfparams":{"dklen":32,"n":262144,"p":1,"r":8,"salt":"e4ca94644fd30569c1b1afbbc851729953c92637b7fe4bb9840bbb31ffbc64a5"},"mac":"f4092a445c2b21c0ef34f17c9cd0d873702b2869ec5df4439a0c2505823217e7"},"id":"216c7eac-e8c1-49af-a215-fa0036f29141","version":3},"test","yaddayadda"], "id":4}
func (*UIServerAPI) ImportRawKey ¶

func (*UIServerAPI) OpenWallet ¶
func (s *UIServerAPI) OpenWallet(url string, passphrase *string) error
OpenWallet initiates a hardware wallet opening procedure, establishing a USB connection and attempting to authenticate via the provided passphrase. Note, the method may return an extra challenge requiring a second open (e.g. the Trezor PIN matrix challenge). Example {"jsonrpc":"2.0","method":"clef_openWallet","params":["ledger://",""], "id":6}
func (*UIServerAPI) SetChainId ¶
func (s *UIServerAPI) SetChainId(id math.HexOrDecimal64) math.HexOrDecimal64

ValidateTransaction(selector *string, tx *SendTxArgs) (*ValidationMessages, error) }
Validator defines the methods required to validate a transaction against some sanity defaults as well as any underlying 4byte method database.
Use fourbyte.Database as an implementation. It is separated out of this package to allow pieces of the signer package to be used without having to load the 7MB embedded 4byte dump.
