Encountered many fields , The form needs to be verified ,db Need encryption , Logs need desensitization , I feel super annoying ,
Make a note of

In the database , Confidential fields cannot be saved in clear text （ Finally started with the database ）, add to _like, _hash, _encrypt Etc , Remove plaintext .
_hash It cannot be decrypted in one direction , To decrypt, you must go to _encrypt, But you can make inquiries ,hash Indexes （ Don't think about confused queries ）
_encrypt Symmetry can be used , Asymmetry can also be used （ Public key private key ）
When exporting , It will also be very troublesome , Because different libraries may have different keys , This leads to the need to decrypt , Re encryption

I ponder over all the sensitive fields in the future , Save a separate table , When querying , Only detailed page decryption congestion , The front-end list page only contains online desensitization data
