Encryption is the process of transforming information in such a way that an unauthorized third party cannot read it; a trusted person can decrypt data and access it in its original form though. There are a lot of popular encryption/decryption methods, but the key to security is not a proprietary algorithm.
Performs a transformation on data, keeping the data from being read by third parties. This type of encryption uses a single, shared-secret key to encrypt and decrypt data. Public-key encryption (asymmetric cryptography). Performs a transformation on data, keeping the data from being read by third parties.o use public-key cryptography to digitally sign a message, A first applies a hash algorithm to the message to create a message digest. The message digest is a compact and unique representation of data.
