u Cryptography 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 u A we can convert some data into encrypted format using various hashing algorithms u MD5 u SHA1 u SHA256 u SHA512 u Every 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 81dc9bdb52d04dc20036dbd8313ed055 length 32 7110eda4d09e062aa5e4a390b0a572ac0d2c0220 length 40 03ac674216f3e15c761ee1a5e255f067953623c8b388b4459e13f978d7c846f4 length 64 d404559f602eab6f...

Such a powerful group of payment companies could centralize digital currencies for a long time to come. Much like how the Lightning Network could profit from Bitcoin, making Silicon Valley the dominant force of how blockchain transactions evolve in the real world. Such a Consortium could appeal to brands, merchants and payment networks who rush to integrate to the leading blockchain partnerships in the world. With over 2 billion consumers, the Libra Network will definitely be among them. Facebook is looking to have 100 members in the governing association. One consortium to rule them all. This is how corporations and financial tech can disrupt banking and how Facebook can become way too powerful, something it’s already been accused of for years. With Microsoft, Google an...
