The Evolution of Encryption and its Impact on Society

Encryption wasn't always used by everyday people and the shift from a world without it to a world where everyone uses it was a major transformation. Human rights and civil rights activists fought for the right to use encryption, which led to the Crypto Wars. Cryptography has been used by military people for centuries to protect their plans and share information. Encryption is when a message is encoded in such a way that only the intended recipient can decode and read it. The US Munitions List includes encryption as a military tool. The Electronic Frontier Foundation is a non-profit digital rights group that protects civil liberties online.

The Evolution of Encryption: From Weak Standards to Crucial Security.

Encryption emerged as a crucial technology that keeps things private and secure during the early days of the internet. The government created Data Encryption Standard (DES) which was very weak and pretending to be secure. Businesses, banks, and people involved in various kinds of activities needed strong encryption, but the government insisted on using DES. Encryption is tremendously important for people who are trying to bring a positive change in society. The need for strong encryption became more and more important as the Internet was growing. Nowadays, encryption is widely used in everyday life to keep our online communication, transactions, and confidential information secure.

The First Crypto War and the Battle for Encryption

The US government traditionally spied on political activists, prompting Phil Zimmermann to develop PGP, a secure communication method for human rights activists. The battle between Phil and the government was the first Crypto War where businesses, internet users, security companies, and banks wanted higher security encryption while the military and law enforcement wanted weaker encryption for better chances of catching criminals. In 1993, Phil Karn's request to export a floppy disc with cryptography was denied as electronic form encryption was then considered a regulated munition. Karn sued the US State Department believing that data contained on a floppy disc should be protected under First Amendment since data in a book already is.

Phil Zimmermann printed his PGP source code in a book format and his publisher started shipping it worldwide, despite the State Department not granting him the right to export the book. Meanwhile, lawsuits were filed against the Arms Export Control Act and the International Traffic and Arms Regulation by Dan Bernstein and Peter Junger, arguing that computer code was protected speech under the First Amendment. The EFF helped these cases, which collectively put pressure on the government to allow people to publish and share strong encryption on the internet. As businesses expressed the need for stronger encryption for their data, these lawsuits set an important precedent for the protection of privacy and free speech in the digital age.

The rise and fall of the Clipper Chip and the victory for civil rights activists.

The US government initially did not allow encryption over 40 bits, but later introduced the Clipper Chip as a more powerful encryption solution. However, the Clipper Chip had a backdoor key built in, which made it insecure. Matt Blaze demonstrated the flaws in the Clipper Chip and this led the government to drop the Clipper Chip idea. Additionally, civil rights activists won a major victory when Bill Clinton signed Executive Order 13026, which removed encryption from the Munitions List and moved the oversight of encryption from the US State Department to the US Department of Commerce. This was a significant win for civil rights activists and marked the end of the government's crypto policy.

The Impact of DES Regulation on Computer Security and the Emergence of Advanced Encryption Standard.

The US government regulated encryption and only allowed 40-bit DES encryption which severely limited computer security. The government ignored the fact that DES could be cracked within 39 days and continued to endorse it. The EFF created a tool called the DES Cracker to demonstrate the vulnerability of DES which could be used by anyone to break the security of financial institutions. Once the DES could be cracked in under a day, the US government released a new cypher called Advanced Encryption Standard with 120-bit strength. The use of triple DES was also allowed. This led to a significant improvement in computer security and showcased the importance of constantly updating technology to keep up with potential security threats.

The first Crypto Wars and its impact on online privacy and security

The first Crypto Wars ended in 2000, allowing for stronger encryption methods and paving the way for greater privacy and security in our online lives. Websites are increasingly using HTTPS to encrypt all communication and tools like HTTPS Everywhere make it easy for us to use. Even everyday products like Facebook's messaging service now use end-to-end encryption. While there are still vulnerabilities in some technology, we can stay vigilant and speak up to protect our privacy and security. When enough of us raise our voices, we can win the next Crypto War.
