encipher
C1Technical / Formal
Definition
Meaning
To convert a message or information into a secret code, typically by substituting letters or symbols according to a specific system.
The process of obscuring or disguising plain text or data using a cryptographic algorithm or cipher to prevent unauthorized access.
Linguistics
Semantic Notes
Primarily used in cryptography, computer security, and intelligence contexts. Denotes a technical, intentional act of encryption, distinct from informal scrambling or hiding.

Learning
Memory Aids
Mnemonic
Think: 'ENter the CIPHER' – you put your message into a cipher to hide it.
Conceptual Metaphor
LANGUAGE IS A LOCKED CONTAINER (enciphering puts the message in a locked box; deciphering unlocks it).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'шифровать' (to cipher/encrypt) – it's a direct match, but 'encipher' is more formal/technical.
- Do not confuse with 'расшифровывать' (to decipher) – they are opposites.
- The prefix 'en-' signifies 'put into', not intensity.
Common Mistakes
- Using 'encipher' for simple hiding or informal coding. / Confusing 'encipher' (to code) with 'decipher' (to decode). / Misspelling as 'incipher'.

FAQ
Frequently Asked Questions
In modern usage, especially in computing, they are largely synonymous. Historically, 'encipher' referred to classical ciphers (character substitution/transposition), while 'encrypt' was broader, covering all encryption methods. Today, 'encrypt' is more common.
'Encode' has a broader meaning: converting data into a specific format for any purpose (e.g., encoding a video file). 'Encipher' specifically means converting into a secret code to conceal meaning. All enciphering is a form of encoding, but not all encoding is enciphering.
Yes, absolutely. While it has historical roots, it is a standard term in technical cryptography for the process of converting plaintext into ciphertext, whether done mechanically, manually, or digitally.
The related nouns are 'encipherment' (the process or result of enciphering) and 'cipher' (the code system itself).
