What are the different methods of encryption in C#?

Common encryption methods in C# include:

1. Symmetric encryption involves using the same key to both encrypt and decrypt data. Common symmetric encryption algorithms include AES (Advanced Encryption Standard), DES (Data Encryption Standard), and 3DES (Triple DES).
2. Asymmetric encryption involves using both a public key and a private key to encrypt and decrypt data. Common asymmetric encryption algorithms include RSA (Rivest-Shamir-Adleman) and DSA (Digital Signature Algorithm).
3. Hash encryption: Data is transformed into a fixed-length hash value through a hash function, and it is irreversible. Common hash encryption algorithms include MD5, SHA-1, SHA-256, etc.
4. Base64 encoding is the process of converting binary data into text format. It is not considered an encryption algorithm, but it is commonly used for encrypting data during transmission.
5. Combining symmetric and asymmetric encryption: Typically, asymmetric encryption is used to encrypt symmetric encryption keys during data transmission to ensure their security.
