Everybody is suggesting electrum... Altough it is a great choice (i'm using electrum and multibit HD myself), i don't think they have the option to import private keys... At least not from the GUI, maybe there's a python script that allows you to do this, but i'm not really aware of one.
I think their keys are always generated from the seed, so no "outside" keys can be imported...
There would be 2 options:
- use bitcoin core (and download the full blockchaing). It allows you to import your private keys. It might not be 100% safe, since you exported your keys from a website!
- download electrum, just run it, generate a seed, generate new keys and addresses, and transfer the bitcoins you have in blockchain to the new address. This is the safest option imo, unless your address from blockchain is known as a tipjar, or a public address that receives frequent coins... In that case you're more or less stuck with the first option.
it does have the option to import and even export. I used to export my key from the blockchain and add it to electrum. and you can do vice versa too! I think their keys are always generated from the seed, so no "outside" keys can be imported...
