Symmetric Encryption Algorithm Basic

Hello, as they security world is increasing everyday, we all have to understand basics. So i will present here a resume concerning Symmetric (Private Key) encryption


    Symmetric encryption uses a single key for encryption and decryption. Both the sender and receiver have the same key  and use it to encrypt and decrypt all messages.

It is more efficient at encrypting large amounts of data than its counterpart ,assymetric encryption (will mention later)

    The Downside of this encryption method  is that it makes it hard to initiate communication the first time and the key have to be send securely to each user


Some Symmetric algorithms:

  • DES: it is an older algorthm that widely used for the period of time dating back to the 1970's. It has bee compromised and no longer secure 

  • 3DES : it was developped as an improvement over DES. Ii improved the encryption by encrypting the data with DES three times with two, or sometimes three keys .while it is a significant improvement over DES, it consumes a lot of processer power and memory resources.

  • AES: it is a very strong encryption algorithm that's commonly used worldwide,very faster than DES and 3DES and provide strong encryption


Thanks. I will present on another post the Assymmetric encryption
