What is Cryptography? Types and Examples You Need to Know

WebA private key, also known as a secret key, is a variable in cryptography that is used with an algorithm to encrypt and decrypt data. Secret keys should only be shared with the key's generator or parties authorized to decrypt the data. Private keys play an important role in symmetric cryptography, asymmetric cryptography and cryptocurrencies. WebIdentity Based Cryptography. Identity Based Cryptography is a type of public key cryptography that uses a widely known representation of an entity's Identity (name, email address, phone number etc.) as the entities public key.

In cryptography, a key is a string of characters used within an encryptionalgorithm for altering data so that it appears random. Like a physical key, it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it.
