Hello Friends, In This Video, I’m Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module

HASHING : –
If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module.
One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit
Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases.
There are many hash functions defined in the “hashlib” library in python.
Some of the most used hash functions are:
MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5.
SHA: Group of algorithms designed by the U.S’s NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits.
Functions associated :
encode() : Converts the string into bytes to be acceptable by hash function.
digest() : Returns the encoded data in byte format.
hexdigest() : Returns the encoded data in hexadecimal format.
