Need a good book on cryptography, which one would you recommend?

Question

Books

I would like to read one, but a good book. I believe that there are hundreds or thousands of books in every field, but only a few really worth reading. I need advice on these units.
I want a book that is as useful as possible, small, but capacious. The goal is to be aware of the basic algorithms, fundamentals, encryption keys, EDS, etc., to know how it works, weak and strong points. It is for self-development that I want to be in the subject, this is far from my specialization, so I would not want to read three-volume books for years either. Thank you.

Answer 1

Schneier, Applied Cryptography.
