Encryption
en-KRIP-shun
/ɪnˈkrɪpʃən/
The process of converting information or data into a code, especially to prevent unauthorized access.
Implies a deliberate act of scrambling data using an algorithm and a key, making it unreadable without the correct key.
The story behind the word. The word 'encryption' comes from the Greek root 'kryptos', meaning 'hidden' or 'secret'. The prefix 'en-' means 'to put into' or 'to make'. So, 'encryption' literally means 'to put into a hidden state' or 'to make secret'. This perfectly describes the process of transforming data into an unreadable form to protect its privacy.
Word relationships
- Coding: Broader, can refer to any system of symbols, not necessarily for security.
- Scrambling: Suggests making something disordered or confused, but less formal or systematic than encryption.
- Obfuscation: Making something obscure or unclear, often to hide its meaning, but not necessarily with a reversible key.
- Decryption: The process of converting encrypted data back into its original form.
- Plaintext: Unencrypted, readable text.
Commonly confused with
