I have a cipher here! Please see if it is the DES algorithm, how to crack it, and what is the password?
The first number is plaintext, and the last code is ciphertext

Isn't it right? You can see from the cipher text which encryption method is used, dude, you too overestimate our strength?

DES encryption generally returns a byte stream. It is estimated that the above processing method is to first encrypt DES and then Base64 encode the byte stream.

The landlord can try to perform Base64 decoding on the ciphertext and analyze the byte stream characteristics.
