of one-way encryption can be viewed in man dgst. Some common options for one-way encryption:-md5# encryption algorithm, encryption algorithm and SHA1,sha224,sha256each algorithm has a corresponding tool sha1sum,sha224sum,sha256sumtwoSymmetric encryptionSymmetric encryption means that data encryption and decryption use the same key, similar to the locks we normally use, and the same key is used to open and close the door.
