An Introduction to Symmetric Encryption

Symmetric encryption is a fundamental concept in the world of data security. At its core, it is a method of encoding and decoding information where the same secret key is used for both the encryption (scrambling) of plaintext into ciphertext (unreadable data) and the decryption (unscrambling) of ciphertext back into plaintext. This single-key approach is why it's also often referred to as secret-key or private-key encryption. The simplicity and efficiency of this method have made it a cornerstone of protecting digital information for many years.
