Python hashlib module

Hashlib Effect:

Encrypt plaintext into ciphertext, there are two methods of encryption Md5,sha

Example Walkthrough:

1.md5 method

1 Import Hashlib 2 3 hash = hashlib.md5 ()4 hash.update ("helloWorld". Encode ( ' Utf-8 ' ))5Print(Hash.hexdigest ())

Printing results:

5eb63bbbe01eeed093cb22bb8f5acdc3

Note:

Python3 the default encoding format is Unicode,update method only accepts bytes, so encode decoding is required

2.sha method

There are many methods for Sha, and the latter is more and more complex, the lower the efficiency of operation. General application sha256

1 hash = hashlib.sha256 ()2 hash.update ("helloWorld". Encode ( ' Utf-8 ' ))3print(Hash.hexdigest ())

Printing results:
