CRYPTOGRAPHY

Cryptography is the practice and study of hiding information.

Related Terms :
Plaintext: Decrypted or unencrypted data (it doesn’t have to be text only)
Encrypt: Scrambling data using an algorithm to make it unrecognizable
Decrypt: Unscrambling data to its original format
Cipher: Another word for algorithm
Secret key: The secret key is a complex sequence of alpha-numeric characters, used as an input to the encryption algorithm. The algorithm will produce a different output depending on the specific key being used at the time. They allow you to scramble and unscramble data. As the same key is used to open or close a door lock, similarly, a same secret key must be used both at sender's and receiver's end to encrypt and decrypt the data. MORE ON SECRET KEYS

Ciphertext: This is the scrambled unrecognisable message produced as output. It depends on the plaintext and the secret key. For a given message, two different keys will produce two different ciphertexts.
