Encryption Keys facts

While investigating facts about Encryption Keys Explained and Encryption Keys Aws, I found out little known, but curios details like:

Blizzard Entertainment buried encrypted text in their anti-cheat software and a useless function which delivered the encryption key for hackers to find. It was a youtube link to a rick roll

how encryption keys work?

Computers cannot be programmed to generate a set of truly random numbers on their own. For things like encryption keys and online gaming sites, companies use RANDOM.org which uses atmospheric noise to develop truly random numbers.

What are encryption keys?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what type of encryption technology uses multiple keys. Here are 15 of the best facts about Encryption Keys Types and Encryption Keys For Dummies I managed to collect.

during the process of encryption and decryption what keys are shared?

1. The one-time pad is the only encryption technique that cannot be broken. If the key is truly random, at least as long as the plaintext, never reused, and kept secret, then the resulting ciphertext will be impossible to decrypt.

2. In 2007 the secret AACS encryption keys used to protect movie DVDs were leaked to the Internet. Digg complied with MPAA demands and began banning accounts which posted the key, drawing widespread attention to its existence.

3. Researchers in Germany have developed a way to extract Android encryption keys literally by freezing the phone, providing full access

4. CloudFlare uses photos of 100 lava lamps in their headquarters every millisecond of every day to generate random keys for their encryption algorithms.

5. In 1989 since the British secret service wanted to eavesdrop more easily on the public it adopted cipher key lengths of 48 bits for over-air/cellular communication to provide poor encryption. Since western forces forced to increase it to 128 bit today the 'ban on encryption' UK movement started

6. Advanced encryption keys sometimes are made from pointing a camera at a wall of lava-lamps, which generate true random numbers for the keys

7. In 1998, when British PM Tony Blair tried to ban encryption, some people at the University of Cambridge compiled a list of about 1000 common cryptographic keys into a book, published it, and then informed the government they would have to ban it.

8. The RSA Factoring Challenge issued in 1977 by the founders of RSA in Scientific American to factor a 129 digit encryption key to two prime numbers and wasn't completed until 1994

9. You can encrypt files in such a way that you achieve plausible denyability if 'FORCED TO DECRYPT'' - by having more than one password: one which decrypts decoy data and one which will decrypt the real secret. If forced to decrypt, give up the decoy key, your secrets remain safe.

10. For encryption with a key length > 40 bits, in India, users are required to deposit the key with the telecom authority

Why must prime numbers be used as encryption keys?

You can easily fact check why do modern encryption algorithms use keys by examining the linked well-known sources.

Nokia was once blackmailed out of millions of dollars by criminals who threatened to release an encryption key used to sign mobile phone software. The criminals got the ransom money and were never caught

Through an ELI5 talk that email isn't private, but can be via server keys and encryption. Now I have an account with Protonmail. - source

Computers generate their shared key by performing modulus math in order to share encrypted communication. - source
