In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

It is always important to verify whether the large file you downloaded is the file you expected to download or not. This is because files may change in some way from the original while downloading.

In the past, we’ve talked about several free tools designed for calculating hashes and generating Checksum files. Most lack many features, and some have an ancient-looking user interface, which is ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

Often, files that are distributed over the Internet are provided with a checksum number for security and file validity. While they are not needed, some people may wish to verify their downloads with ...

Imagine taking a block of data and turning it into a unique string of characters. Like giving it a digital nickname that never changes (unless the data does!). That’s a hash. Whether the original data ...

Cryptographic hash functions are crucial in ensuring the security and integrity of information across diverse industries. They protect sensitive financial transactions in banking, verify data ...
