Bright key + dark key encryption algorithm, advantages: different encryption results each time

The principle is to set a dark key.

Condition: original text, plaintext key, dark key count n
Encryption process:
1. A Random N-bit integer is generated as the dark key.
2. Combine the plaintext key and the hidden key to design an encryption method to generate the ciphertext.
3. The final ciphertext = the ciphertext added to the dark key; (it can also be placed in the middle or back)

Decryption process:
1. Obtain the first n digits of the ciphertext to obtain the dark key.
2. Perform reverse operations on encryption process 2 to obtain the plaintext.

 

Benefit: different encryption results
