I'm not familiar with this term "key stretching" is this the same thing as "work factor" in bcrypt/blowfish?

- dsacco 9y agoNo, "work factor" is a term that (roughly) describes how computationally expensive brute-forcing the digest will be. They're associated terms, but it would be more accurate to think of the work factor as the final result of the key stretching process.
- bogomipz 9y agoAh I see, it's concerned with low entropy. I believe this paper might be the origin of the term(correct me if I'm wrong.) I thought it was a good read if anyone else is interested: https://www.schneier.com/academic/paperfiles/paper-low-entropy.pdf https://www.schneier.com/academic/paperfiles/paper-low-entro...
