For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.

MD5 is an older algorithm that’s considered unsafe for a number of reasons, but it’s still useful for demonstrating how password hashing and cracking work.

What is Proof-of-Work and why is it necessary? How does Bitcoin mining work? What is Bitcoin's hashing algorithm? What is the difficulty adjustment in bitcoin mining and why is it needed? Is Bitcoin ...

Because hashing algorithms works in one direction, the only way to obtain the corresponding plaintext is to guess, a process that can require large amounts of time and computational resources. The ...

Rainbow tables are password cracking tools with origins dating back to research from the early 1980s. Here's how they work and why they haven't stood the test of time.

Proof-of-activity is the blockchain consensus algorithm that uses a combination of proof-of-work and proof-of-stake to create blocks and verify data integrity.

The National Institute of Standards and Technology retired one of the first widely used cryptographic algorithms, citing vulnerabilities that make further use inadvisable, Thursday. NIST recommended ...

SHA-1 (Secure Hash Algorithm 1) dates back to 1995 and has been known to be vulnerable to theoretical attacks since 2005.

The US National Institute of Standards and Technology (NIST) has announced the phasing out of the secure hash algorithm (SHA)-1 in the federal government. The agency said it will stop using SHA-1 in ...
