I am currently writing my master-thesis and I want to state in a subsection, that a one way hash function is not a method of encryption. But because it is a thesis, I must supply a scientific source for such a statement. My first guess was "Applied Cryptography" from Bruce Schneier, but he never explicitly says, that a one way hash function is not a method of encryption.

Can anyone give my a hint where I should look for a solid quote? Internet articles are not allowed in this thesis, a book or scientific paper would be great.


hope this helps! :)

"Hashing is not encryption, but actually a result from an algorithm."

Oracle PL/SQL Programming By Steven Feuerstein, Bill Pribyl (page 939)

"Hashing is not encryption because you can't decipher the original value from the hash value."

MSDN magazine, Volume 18, Issues 7-12 (page 55)

"Technically, hashing is not encryption ..."

"Hashing is not encryption"

  • $\begingroup$ Thanks, that's perfect! Exactly what I needed. A shame I do not have enough reputation yet to vote this up. $\endgroup$ – Demento Apr 8 '11 at 12:45

    $\begingroup$ Seriously, you don't need a source for this statement! It's like saying a real number has no imaginary part. It's obvious, and the one-sentence explanation should be enough. If I was reading a thesis where this was cited from somewhere I would smile and think "that's odd". $\endgroup$ – Glen Wheeler Apr 8 '11 at 19:13

You don't need a source because hashing is by definition not reversible, therefore it is by definition not encryption. As a source for that statement goes, any book which covers hashing or cryptography would do (like the one you suggest).
