Symmetric Encrypt & Decrypt
Algorithm
Key
Symmetric encryption is a type of encryption where the same key is used to both encrypt and decrypt information. It is also called single key encryption or secret key encryption. Symmetric encryption is fast and efficient, but it requires a secure way to share the key between the sender and the receiver. Some examples of symmetric encryption algorithms are AES, DES, RC4. Symmetric encryption is widely used for data protection, authentication and digital signatures.
