Featuring encryption, anonymization, hashing, and access controlNetwork security incidents occur now and then, mostly caused by data leakage. Data security has aroused widespread concern, and the community keeps working hard on approaches to simplify data security, especially in sensitive data protection.Sensitive data includes but is not limited to personally identifiable information (PII) like names, ID numbers, passport numbers, driver’s license numbers, contact information like addresses, phone numbers, account credentials like usernames, passwords, PINs, and financial information li...

When doing data exchange among different parties, there is a frequent need of encrypting data or file and sending it to partner and asking partner to use corresponding key to decrypt the data or file. A famous way of exchanging data is using asymmetric keys where no secret key needs to be shared. One party can just use the public key shared by partner to encrypt the data and the other party uses the private key to decrypt the data.Today, we will introduce how to use PGP to encrypt and decrypt data on MacOS. Pretty Good Privacy (PGP) is an encryption system used for both sending encrypted ...

The biggest problem is that you must be able to verify that you're encrypting to the correct key. Without it, encryption would be practically useless, as anyone could perform a man-in-the-middle attack on the connection and remain undetected.In typical SSL/TLS, as well as other protocols using X.509, this verification is performed by "certification authorities", which are explicitly marked as "trusted" by web browsers and operating systems. Unfortunately, these CAs usually charge a decent amount of money even for the simplest, automatedchecks. They also get hacked...
