Advanced Encryption Standard (AES) is a widely used encryption algorithm that secures sensitive data. It was established by the U.S. National Institute of Standards and Technology (NIST) in 2001 to replace the older Data Encryption Standard (DES).AES operates using a symmetric key encryption method, meaning the same key is used for both encrypting and decrypting data. It supports key sizes of 128, 192, or 256 bits, which enhance its security. The algorithm divides the data into blocks, which are then processed in multiple rounds of transformation to turn plaintext into ciphertext, making it unreadable without the key.In the context of cryptocurrencies, AES ensures the protection of private keys, transaction data, and wallet information. Secure storage and transmission of this data are crucial to prevent unauthorized access and maintain user privacy. Using AES helps in building trust within the ecosystem, as users feel more secure knowing their financial information is encrypted. Overall, AES is an essential component of maintaining the integrity and security of digital assets.
