I am looking to take an Intro to Cryptography course and picked up a copy of the textbook, titled "Understanding Cryptography" by Paar/Pelzl.[1] I've seen a lot of debate on cryptography books on HN and am wondering what the opinion is about this textbook before I crack it open and start studying.<p>[1] http://www.springer.com/computer/security+and+cryptology/book/978-3-642-04100-6
