Glossary
========
.. glossary::
:sorted:
plaintext
User-readable data you care about.
ciphertext
The encoded data, it's not user readable. Potential attackers are able
to see this.
encryption
The process of converting plaintext to ciphertext.
decryption
The process of converting ciphertext to plaintext.
key
Secret data is encoded with a function using this key. Sometimes
multiple keys are used. These **must** be kept secret, if a key is
exposed to an attacker, any data encrypted with it will be exposed.
symmetric cryptography
Cryptographic operations where encryption and decryption use the same
key.
asymmetric cryptography
Cryptographic operations where encryption and decryption use different
keys. There are separate encryption and decryption keys.
authentication
The process of verifying that a message was created by a specific
individual (or program). Like encryption, authentication can be either
symmetric or asymmetric. Authentication is necessary for effective
encryption.
ciphertext indistinguishability
This is a property of encryption systems whereby two encrypted messages
aren't distinguishable without knowing the encryption key. This is
considered a basic, necessary property for a working encryption system.
