Based on the analysis in the previous article "Introduction to Real Data Encryption Using DES (analysis)", Java can be used to encrypt strings, however, the legacy problem is that the string cannot be decrypted, because after the encrypted byte array is converted into a string, it will be different from the original byte array, and there will be fewer digits, I don't know why. Isn't a one-to-one conversion
