As businesses and banks started digitizing their data, the need for encryption technology became increasingly important. The development of the internet in the 1990s further highlighted the need for privacy and security, making encryption one of the solutions adopted to protect sensitive information.
In the early days of the internet, encryption became important for ordinary people who wanted to do commerce or have private conversations. Military-grade encryption was backdoored by the government with denial of that fact and they innocently pretended that it was secure.
The US government insisted on using 40-bit DES encryption despite knowing it was weak, leaving data vulnerable to attacks. Encryption is vital for protecting against government surveillance and for those trying to change the government or corporate policies.
