Explain encryption and cryptography in laypersons terms?
Encryption is the transformation of data into a form (a cipher) that is, for most intents and purposes, impossible to read with out the appropriate decoder (a cryptographic key). Its purpose is to ensure privacy by keeping information hidden from anyone for whom it is not intended, even those who have access to the encrypted data. Decryption is the reverse of encryption; it is the transformation of encrypted data back into an intelligible form.
