1. DotNet encryption-Hash Encryption

Notes:

Hash encryption type:

1. MD5 128-bit

2. SHA-1 160-bit

3. SHA-256 256 bits

4. SHA-384 384 bits

5. SHA-512 512 bits

Ii. DotNet encryption-symmetric encryption

Notes:

Symmetric encryption type:

1. Rijndael algorithm: the encryption algorithm that uses repeated operations allows the length of data blocks and keys to be variable. The length of data blocks and keys varies independently.

2. DES algorithm:

A) DES encryption: The block encryption method is used. The 56-bit key is used to encrypt 64-bit plaintext, And the 64-bit ciphertext is finally generated.

B) 3DES encryption: uses a 168-bit key and triple encryption, which is slow.

C) TripleDES encryption: uses two key pairs to encrypt and decrypt data three times.

3. RC algorithm:

A) RC2 encryption: The key length is variable, and the 64-bit block encryption is adopted for plaintext.

B) RC4 encryption: A byte stream-oriented encryption algorithm with variable key length is used based on random replacement.

C) RC5 encryption: uses a grouping encryption algorithm (including key extension, encryption algorithm, and decryption algorithm) with variable group length, key length, and number of encryption iterations ).

D) RC6 encryption: RC6 inherits the RC5 Cycle Shift idea. RC6 is the input plaintext, Which is expanded from the original two areas to four blocks.
