Before we get a hundred posts about SHA-1 being "broken" would eveyrbody
please read:

and maybe *ALL* the contributions way down at the bottom of the original
post link?
You're still looking at thousands of years or millions of dollars to break
SHA-1 if you want to start TODAY.
The wise reader will put "Upgrade to SHA-256" on their "ToDo" list and go
back to work now. :-)
Though I did find the post to add meta-data such as the character
distribution to the hash interesting...
The odds on a SHA-1 being the same for two plain-texts *AND* having the
same number of E's in the plain-texts? Really really really low, seems to
me.
