How Encryption Works - and How It Can Be Bypassed
The debate between privacy and national security has never been more heated, with Apple and other tech firms going up against the government. So how are text messages encrypted, and what are the controversial "backdoors" that could allow access to them?

What is Encryption?
We use forms of Encryption everyday, but have you ever wondered what it is? Or how encryption works?
Cybercriminals look for data to use for stealing or extorting money from their victims. In order to prevent this, encryption software or encryption hardware can be used to secure data.
Encryption involves converting readable data into code and offers a secure way of data being stolen. Watch this video to learn all you need to know about encryption., from how it works and
to where you can use it.

Encryption - Symmetric Encryption vs Asymmetric Encryption - Cryptography - Practical TLS
Encryption is how data confidentiality is provided. Data before it is encrypted is referred to as Plaintext (or Cleartext) and the process of encryption turns it into Cipher text. Cipher text should be unintelligible. Only the intended recipient should have the ability to Decrypt data, which turns Cipher text back into Plaintext.
There are two strategies for Encryption: Symmetric Encryption vs Asymmetric Encryption. In this video we discuss each of their strengths and weaknesses, and provide a simple illustration of them both.
This lesson is a free sample lesson from the the most effective TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Co...

Encryption is how data confidentiality is provided. Data before it is encrypted is referred to as Plaintext (or Cleartext) and the process of encryption turns it into Cipher text. Cipher text should be unintelligible. Only the intended recipient should have the ability to Decrypt data, which turns Cipher text back into Plaintext.
There are two strategies for Encryption: Symmetric Encryption vs Asymmetric Encryption. In this video we discuss each of their strengths and weaknesses, and provide a simple illustration of them both.
This lesson is a free sample lesson from the the most effective TLS and SSL training course ever created. No instructor rambling on about pointless stories. No slides with massive walls of text. No time wasting. Only simple, effective, and precise explanations. Complimented with practical illustrations and visuals.

Encryption is the process scrambling critical information before transmitting them to a receiver. Using encryption allows users to maintain secrecy and prevent hackers from reading data while it is in transit or at rest. Coupled with decryption, they form the heart of cryptography which forms a critical part of network security around the world.
