[Part 1 of this article begins with a review of various application security level categories and a look at hash algorithms as a basic level of security. Part 2 covers the basics for optimizing ...

The RSA algorithm is a feast of genius that combines theoretical math and practical coding into working asymmetric cryptography. Here’s how it works.

A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read.

Chinese researchers claim quantum technology is reaching a point where a quantum device will soon be able to crack RSA 2048 public key encryption.

For example, RSA algorithms multiply large prime numbers to generate public keys but require corresponding private keys to use the original primes.

Quantum computing might have more significant impact on public-key cryptography, which is used to set up secure connections online. For example, this is used to support online shopping or secure ...

Symmetric cryptography, which encrypts the bulk of our data today (and does not include the RSA algorithm), can easily be strengthened to protect against quantum computers.

For example, this is used to support online shopping or secure messaging, traditionally using the RSA algorithm, though increasingly an alternative called elliptic curve Diffie-Hellman.

Now Is the Time to Plan for Post-Quantum Cryptography Panelists from an RSA Conference keynote agreed that organizations need to begin work on PQC migration, if they haven't already.

Ronald Rivest helped come up with the RSA algorithm, which safeguards online commerce. Now he’s hoping to make democratic elections more trustworthy.
