Spring Security encryption three ways to encrypt

Encryption

One-way encryption single-entry encryption, the value that the client will pass is encrypted (using a specific encryption method), the original value and the encrypted value passed in the past, the server side will also encrypt the original data (both methods of encryption consistent), and finally match the value of the encryption after the equality. Equality is passed, otherwise it is not passed.

Symmetric encryption bidirectional, both encrypted and can be decrypted.

　　

Public key cryptography private key and secret key, public key is exposed to the outside, the secret key only knows, the transmitted data uses the public key to encrypt, obtains after uses the secret key to decrypt.
