Security firm Mandiant has released a database that allows any administrative password protected by Microsoft’s NTLM.v1 hash algorithm to be hacked in an attempt to nudge users who continue using the ...

Hashing transforms data into a fixed-length cryptographic fingerprint that ensures integrity and authenticity. Every block in a blockchain contains its own hash and the previous block’s hash, forming ...

The quest to make biometric data private and secure has led to the development of biometric hashing. Hashing is a one-way process in which an algorithm called a cryptographic hash function takes an ...

In the realm of computer science, it’s hard to go too far without encountering hashing or hash functions. The concept appears throughout security, from encryption to password storage to crypto, and ...

Computing practitioners encounter hash functions almost every day, although they may not necessarily be the center of attention. When you install software packages or updates, the authenticity of a ...

Double hashing is designed to reduce clustering. It does this by calculating the stride for a given key using a second, independent hash function. Thus, two objects will have the same probe sequence ...

As we have seen in previous videos, it happens sometimes that two keys yield the same hash value for a given table size. This is called a “hash collision” or just “collision.” Why do hash collisions ...

Cryptography, a cornerstone of modern information security, encompasses a vast array of techniques and tools designed to protect sensitive data from unauthorized access and tampering. Within this ...

Hashing is a cryptographic process that allows converting any type of data into a unique fixed-size numeric value called “hash”. Hashes are generated using hashing algorithms that are both ...

Argon2 is a password-hashing function that summarizes the state of the art in the design of memory-hard functions and can be used to hash passwords for credential storage, key derivation, or other ...
