For what it's worth I can verify thefragile99's statement that the hash alone should be quite safe - a thief would need both the wallet file and the password/encryption key to be able to unlock it.  If you do go ahead with the suggestion (do your own research first), just make sure that the hash and result are being transmitted securely.

Unless you have some reason to suspect that someone else has a copy of the wallet then there should be minimal risk.

That said - I hope the computer in question is being kept offline!  Looking out for you, you've mentioned a relatively significant amount of numbers in this thread, you will be a target to unscrupulous types.  Please be careful.
