Wallets and (un)compressed keys

[ArpFlush]

Hello everyone,

Can someone list me what (desktop) wallets use uncompressed private keys (and which ones use compressed pk's)?
If I'm correct, a client that uses uncompressed keys (Electrum) can't import compressed keys, right? because you will end up with a different bitcoin address.

Thanks ;-)

Most wallets should now generate compressed keys. If the wallet can export the private key in WIF (Wallet Import Format) you can see by the prefix whether the public key should be hashed compressed or not. Prefixes starting with 5 are for uncompressed keys while L and K are for compressed keys.

Generally speaking all wallets should be able to handle both compressed and uncompressed pubkeys.

The only wallet I know of that only supports uncompressed keys is armory. All other wallets that I know of are able to support both types.

Good to know that, thanks all.
