You are talking about making a combined hash function from MD5 and SHA-1. Keep in mind that it is not trivial. For instance, if you just output both SHA-1 and MD5, you are actually only as strong as the weakest hash function (trivially for preimage, but also true for collisions, see [1]).

If you are interested in hash function combiners, have a look at Robust Multi-Property Combiners for Hash Functions [2], a recent paper on the topic. It aims at getting several properties at the same time (preimage resistance, collision resistance). For simpler schemes with a single property, just explore the bibliography at the end of the paper.

What you are saying is completely irrelevant, because we are talking about checksumming data, not hashing passwords.

Good link, thanks for sharing :)

Edit: the actual figure is 90%

For other people struggling to read this comment: "(" is on the same key as "5" on Azerty keyboards.

It's also a capital 9. I'm so ashamed. The number is supposedly 90%.

Oh, my bad, I got confused with the brackets (which are not on a digit key). I really should have checked. See, we all make mistakes!

Did you know you can edit your post? I think yours deserve it.

It appears that after a certain amount of time the edit capability is unavailable.

Ideas that might help:

* set all redundant accounts to redirect mail to a main one

* do write the identifiers and passwords on paper notes, and have her keep them, for instance, inside her wallet

In short: because measuring effects the information, tampering cannot be concealed.

Thanks for the link!

However, it seems like the page linked in the post is not available anymore.

Well, you are talking about a gap of 14 years: the site's been reorganised since then, but all the content is still there.

I think this can be described as the ongoing eternal september [1].

It might be useful to allow changing one's guess. It's pretty annoying when you misclick in the middle of the map and cannot pick the correct location.
