You can’t un-ring a bell, but you might be able to un-hash an email, depending on whom you ask. In order for marketers to safely use hashes for targeted advertising, they must stay abreast of the ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

As the federal government comes under attack by increasingly sophisticated threat actors, encrypting data, hashing passwords and salting hashes are becoming more important.

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 ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

Despite being something of a cryptography veteran, SHA-1 hash algorithm faces an uncertain future as OpenSSH and Libssh choose to block it.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to retire it ...
