Python hashlib Module

Hashlib Module

• For cryptographic related operations, instead of the MD5 module and the SHA module
• Mainly provides SHA1, SHA224, SHA256, SHA384, SHA512, MD5 algorithm

# MD5 Obsolete Import Md5hash = Md5.new () hash.update (' admin ') print hash.hexdigest ()

# sha Obsolete Import Shahash = Sha.new () hash.update (' admin ') print hash.hexdigest ()

 hashlib encryption:

import hashlib# ######## md5 ####### #hash = HASHLIB.MD5 () hash.update ("Evescn" . Encode (' Utf-8 ')) print (Hash.hexdigest ()) # ######## SHA1 ####### #hash = HASHLIB.SHA1 () hash.update ("Evescn". Encode (' Utf-8 ') print (Hash.hexdigest ()) # ######## sha256 ####### #hash = hashlib.sha256 () hash.update ("Evescn". Encode (' Utf-8 ') ) Print (Hash.hexdigest ()) # ######## sha384 ####### #hash = hashlib.sha384 () hash.update ("Evescn". Encode (' Utf-8 ')) Print (Hash.hexdigest ()) # ######## sha512 ####### #hash = hashlib.sha512 () hash.update ("Evescn". Encode (' Utf-8 ')) print ( Hash.hexdigest ()) # Input Result: 48fc6919f119605c4064ea7d81ac6b34f2e9afa0fbde5b05a444f7bc75d6695fbb84b8d005406e832ad8456184cd36fd3bd88dd1fff2392eb873 a1fe7aff9e6332bd7a353e8027e7a2aa54ba604fbe66f853212f23b4fbae80883972fc8a24a92c04b9cb7c3ee01840ccb98f5c3edf897d15f9fae7931 c755048f72babc0b6f016c1581a51c4af7d3bef64a1c21156866a68cccf37d6914bacde9f0d7b83e328bc2025847f6754b6eec57be91f06e6ad5ca17d 1b 

python3,2 type of encryption writing format

Import hashlib# ######## md5 ####### #hash = HASHLIB.MD5 () hash.update ("Evescn". Encode (' Utf-8 ')) print (Hash.hexdigest () ) hash = HASHLIB.MD5 () hash.update (b "EVESCN") print (Hash.hexdigest ()) # Input Result: 48fc6919f119605c4064ea7d81ac6b3448fc6919f119605c4064ea7d81ac6b34

Although the above encryption algorithm is still very strong, but the time has the flaw, namely: through the collision library can reverse the solution. Therefore, it is necessary to add a custom key to the encryption algorithm to do encryption.

Import hashlib# ######## md5 ####### #hash = HASHLIB.MD5 ("Evescn". Encode (' Utf-8 ')) hash.update ("Evescn". Encode (' Utf-8 ') ) Print (Hash.hexdigest ()) # input Result: d6fd21d81a89fa360fe2ee37c6417b6f

Python also has an HMAC module that internally creates keys and content for us to process and then encrypt

Import Hmach = Hmac.new (b "EVESCN") h.update (b "EVESCN") print (H.hexdigest ()) # input Result: bd4e50d0a9c686fad0a0be089ba918be
