What is Private Keys?

A private key, also known as a secret key, is a variable in cryptography that is used with an algorithm to encrypt and decrypt code. Secret keys are only shared with the key's generator, making it highly secure. Private keys play an important role in symmetric cryptography, asymmetric cryptography and cryptocurrency. The complexity and length of the private key determine how feasible it is for an interloper to carry out a brute force attack and try out different keys until the right one is found.
