What are the events related to passwords and encryption in life?

1. Password is a science with a long history. Ciphers were used to deliver secret messages during the wars between ancient Greece and the Persian Empire. In modern and modern wars, codes are indispensable for transmitting intelligence and commanding wars, and they are also inseparable from diplomatic struggles.

2. This is a successful combination of cryptography and linguistics. The Navajo code has become a code that has never been deciphered in history.

3. During World War I, on January 17, 1917, the British army intercepted a telegram encrypted with Germany's highest diplomatic code 0075. This unimaginable password system consists of 10,000 words and phrases, corresponding to 1,000 numerical code groups.

4. The theft of Mt.Gox The theft of Mt.Gox remains the largest cryptocurrency theft in history. Between 2011 and 2014, more than 850,000 Bitcoins were stolen.

5. After the establishment of HHTP confidential communication, we mainly use the AES encryption algorithm for data communication.

6. The situation abroad is not optimistic either. On September 22, 2016, the global Internet giant Yahoo confirmed that the account information of at least 500 million users was stolen in 2014. The stolen content included user names, email addresses, phone numbers, dates of birth and partial login passwords. What are the types of passwords? Types of passwords that are not stipulated in the Cryptozoology Law

Ordinary passwords protect state secrets and protect confidential-level and secret-level state secrets; commercial passwords protect information that is not state secrets. Legal basis: Article 6 of the Cryptozoology Law stipulates that the state implements classified management of cryptography. Passwords are divided into core passwords, ordinary passwords and commercial passwords.

The following statements are not in compliance with the cryptography law: The types of passwords stipulated in the cryptography law are: core passwords, ordinary passwords and commercial passwords. Core passwords and ordinary passwords are used to protect state secret information and are state secrets.

The types of passwords stipulated in the cryptography law include: core passwords, ordinary passwords and commercial passwords. Core passwords and ordinary passwords are used to protect state secret information and are state secrets. Citizens, legal persons and other organizations can use commercial passwords to protect network and information security in accordance with the law. Commercial passwords are used to protect information that is not state secrets.

Common passwords and commercial passwords. The cryptography law divides passwords into core passwords, ordinary passwords and commercial passwords, and implements classified management. Core passwords are used to protect national top-secret, confidential, secret-level information, ordinary passwords are used to protect national secret-level, secret-level information, and commercial passwords are used to protect information that is not state secrets.

Cryptotype types include Morse code, Caesar shift cipher, barrier transposition method, etc. Morse code, Morse code consists of two symbols, dots and dashes, according to the following principles. One point is a basic signal unit, and the length of each stroke is equivalent to the length of 3 dots. What are typical cryptographic technologies?

Cryptographic technology is a technology for encrypting and decrypting information and plays a vital role in modern communications and information security. Typical cryptographic technologies include symmetric key encryption, public key encryption, hash algorithms, digital signatures, etc. Symmetric key encryption: Symmetric key encryption is a technique that uses the same key for encryption and decryption.

Typical cryptographic techniques include symmetric encryption, asymmetric encryption and hash functions. Symmetric encryption uses the same key for encryption and decryption, which is faster but has more complicated key management. Asymmetric encryption uses public and private keys for encryption and decryption, which is more secure but slower.

Typical cryptographic technologies include the following: cryptographic algorithms, key management, and cryptographic protocols. Cryptographic technology is mainly used to achieve the confidentiality of information. Technology for encrypting, analyzing, identifying and validating information, and managing keys. Cryptographic technology and its research and application fields are constantly evolving.
