Which encryption algorithm is commonly known for its use in secure file transmission?

The Advanced Encryption Standard (AES) is widely recognized for its strong security and efficiency in securing data, making it a popular choice for encrypting files during transmission. AES operates as a symmetric key encryption algorithm, which means that it uses the same key for both encryption and decryption processes. This attribute allows for rapid encryption and decryption, which is essential for maintaining performance in applications involving secure file transfers.

Additionally, AES supports various key lengths (128, 192, and 256 bits), which provide different levels of security. The robustness of AES against cryptographic attacks, combined with its speed and versatility, has led to its adoption as a standard encryption method by many organizations and protocols, including those designed for secure file transmission.

In contrast, RSA, while also a well-known encryption algorithm, is primarily used for securing data in transit via key exchange and digital signatures rather than for bulk data encryption. Blowfish is another symmetric key algorithm known for its speed and effectiveness but is less common than AES in modern implementations. SHA-256 is a cryptographic hash function and does not encrypt data, but rather generates a fixed-size hash value, making it useful for integrity checks rather than secure file transmission. Thus, AES stands out as the most suitable choice for secure
