Cryptography has crept into everything, from web browsers and email programs to cell phones, bank cards, cars and even into medical implants. Thus, an increasing number of people have to understand how crypto schemes work and how they can be used in practice. We wanted to create a book that teaches modern applied cryptography to readers with a technical background but without an education in pure mathematics.  

Irresponsible ownership of data is the cause of many leaked emails, data, and other damaging information. Securing a user’s personal information is the job of software developers. If you, as a developer, can decrypt the information stored in the database of the system you are working on, then so can anyone else. In Cryptography in .NET Succinctly, Dirk Strauss will take readers through generating cryptographic signatures, hashing and salting passwords, and when and how to use symmetric vs. asymmetric encryption. 

The Blockchain is to Bitcoin as gold is to jewelry. 

SHA-1 Has Been Compromised In Practice
The CWI Institute and Google have successfully demonstrated a practical SHA-1 collision attack by publishing two unique PDF files that produce the same hash value.
 

Microsoft,Google and Mozilla will stop SHA-1 SSL cert support from 2017
