The longer key will make the decryption procedure a bit slower even in the
passphrase attacks, but a very weak passphrase (using a very common
passwords) is still a trivial exercise to crack.

Am I right in assuming that an encrypted file/email is only as secure as the
passphrase used for the private key? i.e. If i use the passphrase 'password'
then does it become irrelevant what key size I use to encrypt the data?

If someone can please briefly explain this to me I would be much
appreciative.

Thanks.
