I was new to cryptography. And I know that in the world of cryptography there are two types of Symmetric Algorithms:
- Stream Cipher (RC4, Salsa & Chacha)
- Block Cipher (DES, AES)
And when doing some research on their implementation, I only looked at file encryption & decryption software products that use the AES algorithm (Block Cipher in general). (i know that AES is secure)
Can anyone help me answer the question whether Stream Cipher can be used to encrypt files like: .txt .docx .exe .zip?
I know this is a stupid question. Please forgive me.
