An overview to Cryptography

uCryptography is a method of protecting information and communications through the use of codes so that only those for whom the information is intended can read and process it

uA we can convert some data into encrypted format using various hashing algorithms

uMD5

uSHA1

uSHA256

uSHA512

uEvery such algorithm takes some data and produce a fixed length output called as cipher

Example using Python

import hashlib

data=input("Enter data to encrypt ")

a=hashlib.md5(data.encode()).hexdigest()

b=hashlib.sha1(data.encode()).hexdigest()

c=hashlib.sha256(data.encode()).hexdigest()

d=hashlib.sha512(data.encode()).hexdigest()

print(a,len(a))

print(b,len(b))

print(c,len(c))

print(d,len(d))

Output

Enter data to encrypt 1234
