# How Can I import Multibit Private Key into Electrum or Blockchain.com

(Asked by: username_0 on 2021-03-05)

I am having trouble importing a multibit private key into electrum and blockchaing.com. The key is declared invalid.

the key looks like this

U2FsdGVkX1+vNknxxxxxxxxxxxxxxU/KiWdlFKlBCv0y613C+rP2t3JMGnuR2xxxxxxxxk/gNe9S
lvv/OJQGbRJ4qP07m3CII4FLvovMg71F8cXSav15QeIxxxxxxxxf

Is this the entire key?
Or
Do I extract segments from the key above? What segment?

The presence of '/' and '+' indicate that your key is encoded in [Base64](https://en.wikipedia.org/wiki/Base64)

It is likely that the wallets you mention need the key to be presented in [Wallet Import Format (WIF)](https://en.bitcoin.it/wiki/Wallet_import_format)

For example, [Importing your private keys into Electrum](https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/) says

> Electrum supports mini private keys and full sized keys in Wallet Import Format (WIF).

also [How to import keys to Blockchain.info?](https://allprivatekeys.com/how-to-import-private-keys) says

> You can enter WIF (Wallet Import/Export Format) or compressed private key.

I would decode the Base64 into Hexadecimal and then follow the procedure described for WIF.
