comment Attack vectors introduced by compilers
@Martin Berger: I'm not aware of any compiler doing automatic memoization. I guess this would be a good question for Stack Overflow.

comment Is it fair to assume that SHA1 collisions won't occur on a set of <100k strings
You might find this Stack Overflow question and its answers useful stackoverflow.com/q/862346/57428 It uses MD5 in the same scenario, but based on the file contents.

comment What alphanumeric string length can be used to guarantee no hash collisions from CRC-64?
@brandx: You have two paths. Path 1 is to search for analysis of CRC64 specifically - maybe one can strictly prove something given how CRC64 works under the hood and how it treats data. Path 2 is to assume that CRC64 is like a crypto hash - hashes anything into random-looking stuff and then you can't have a guarantee unless you test an exact string set.
