A secure hashing algorithm, or SHA, changes data by creating a hash digest unique to each plaintext message. The two main types of SHAs are SHA-1 and SHA-2.| Encryption Consulting
In this episode of WP Builds entitled "Feeling Insecure? Episode #3," Nathan Wrigley and Tim Nash explore various aspects of WordPress security. Tim shares insights into his background in cybersecurity, including his past experience with physical penetration testing. We discuss the Patchstack report on WordPress security, noting an increase in vulnerabilities but reassuring listeners that more vulnerabilities being found isn't necessarily alarming. We get into the complexity of vulnerabilitie...| WP Builds
Encryption and hashing are very similar types of data manipulation, but they are used for different types of use cases. Read on to learn the difference!| Encryption Consulting
Cryptography is the study of securing communications from outside observers. It comes in several different forms, including symmetric, asymmetric, and hashing.| Encryption Consulting
I've just set up my first hash table after a bit of studying; it's time to write about it! Docendo discimus ~| Randy Gaul's Game Programming Blog
It was recently discovered that some surprising operations on Rust’s standard hash table types could go quadratic. Perhaps the simplest illustration is this snippet from a comment, here simplified even further: use std::collections::hash_set::HashSet; fn main() { println!("populating..."); let mut one = HashSet::new(); for i in 1..5000000 { one.insert(i); } println!("cloning..."); let mut two = HashSet::new(); for v in one { two.insert(v); } } In this example, the first loop (populating one...| Accidentally Quadratic
