Python - MD5 , SHA-1, SHA-256, & SHA-512 Hashing

Hashing is the transformation of any given key or string of characters into a new value. The new value is typically a short, fixed-length key that represents the original string and makes it simpler to find or use. Please note that once this hash is created and saved to the database, it cannot be changed back to your original password. MD5 hash in Python MD5 (Message-Digest algorithm) is one of the most popular hash functions. It produces a hash value of 128 bits. Originally, MD5 was designed to be a cryptographic hash function. However, it has a large number of known vulnerabilities. MD5 can still be used for checksums to check the integrity of data, but only against accidental corruption. It is still suitable for non-cryptographic uses, such as determining the partition of a specific key in a distributed database. Example:  Use hashlib.md5() method to generate an MD5 hash value from a String.   # Python3 code to demonstrate the MD5 import hashlib   # initializing the string str = &q

Hashing in Go Language - MD5 ,SHA-1, SHA-256, & SHA-512

What does Hashing mean? A secure password hash is an encrypted sequence of characters obtained after applying certain algorithms and manipulations on user-provided password, which are generally very weak and easy to guess. Please remember that once this password hash is generated and stored in the database, you can not convert it back to the original password. MD5 hash in Go The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption. It remains suitable for other non-cryptographic purposes, for example for determining the partition for a particular key in a partitioned database. Example: Go-MD5 to hash a String package main //Required imports import ( "crypto/md5" "encoding/hex"
