Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents.

Modern cryptography goals:

Confidentiality,
Data integrity,
Non-repudiation,
Authentication,

plaintext - original message ,
ciphertext - coded message ,
cipher - algorithm for transforming plaintext to ciphertext ,
key - info used in cipher known only to sender/receiver ,
encipher (encrypt) - converting plaintext to ciphertext ,
decipher (decrypt) - recovering ciphertext from plaintext,
cryptography - study of encryption principles/methods,
cryptanalysis (codebreaking) - deciphering without knowing key,
cryptology - field of both cryptography and cryptanalysis,

Symmetric Key Cryptography ,
Asymmetric Key Cryptography,
Hash Function,

Caesar Cipher,
Rail-fence Cipher,
