Python hashlib Module

Hashlib Module

I. Hashlib module

For cryptographic related operations, the 3.x force replaces the MD5 module and the SHA module, providing

: SHA1,SHA224,SHA256,SHA384,SHA512,MD5 algorithm.

1. Use the Hashlib module for MD5 encryption.

Import= hashlib.md5 () m.update (b"Hello") m.update (b " It ' s me " )print(m.hexdigest ()) m.update (b"It ' s been a long time since last Time we ... " )print(M.digest ())

Note: Hashlib.md5 (): Creates a MD5 encryption parameter.

Note: the variable. hexdigest (): Hexadecimal encryption.

Note: Variables. Digest (): Binary encryption

Note: There are a total of 32 values.

2. Encrypt using the SHA1 algorithm.

Import= hashlib.sha1 () s2.update (b"ABC")Print (S2.hexdigest ())

Note: There are a total of 38 values.

3. Encrypting using the SHA256 algorithm

S2 = hashlib.sha256 () s2.update (b"ABC")print( S2.hexdigest ())print(len (S2.hexdigest ()))

Note: There are 64 encrypted values.

4. Encrypt using the SHA384 algorithm.

Import= hashlib.sha384 () s2.update (b"ABC")Print  (S2.hexdigest ())print(len (S2.hexdigest ()))

Note: There are 96 encrypted values.

5. Encrypt using the SHA512 algorithm.

Import= hashlib.sha512 () s2.update (b"ABC")Print  (S2.hexdigest ())print(len (S2.hexdigest ()))

Note: There are 128 encrypted values.

Two. Advanced Encryption algorithm

Import= hmac.new ('wueiqi') h.update ('Hellowo ' )print h.hexdigest ()

Note: the equivalent of encryption and then a layer of encryption. Double-layer encryption.

Import= hmac.new (b"xsk","y wind x". Encode ( encoding="utf-8")print(h.digest ()) print (H.hexdigest ())

Note: double-layer encryption.

Note: To add a Chinese key, convert the character type.
