encrypt
C1Formal, Technical
Definition
Meaning
To convert information or data into a code, especially to prevent unauthorized access.
To systematically transform readable data (plaintext) into an unreadable format (ciphertext) using an algorithm and a key, for the purpose of confidentiality, security, or privacy.
Linguistics
Semantic Notes
Primarily a technical term from computing and cryptography. Implies a reversible process (decryption). Often used in contexts of digital security, privacy, and data protection.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. Spelling and pronunciation are consistent.
Connotations
Identical connotations of security, privacy, and technical sophistication in both varieties.
Frequency
Equally common in both UK and US English due to the global nature of computing terminology.

Learning
Memory Aids
Mnemonic
Think of a 'crypt' as a secret, hidden place. To EN-CRYPT is to put information into a secret code.
Conceptual Metaphor
SECURITY IS A LOCKED CONTAINER (data is placed inside a locked digital container).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'зашифровать' (to encode/encrypt) and 'закодировать' (to code, which can be for compression or error correction, not necessarily security). The English term is specifically for secret codes.
Common Mistakes
- Using 'encrypt' for irreversible processes like hashing. Confusing 'encrypt' (make secret) with 'encode' (convert format, e.g., MP3). Misspelling as 'incrypt'.

FAQ
Frequently Asked Questions
No. Encoding (e.g., Base64, URL encoding) changes data format for transmission/storage but is not secret. Encryption specifically uses a key to make data unreadable without authorization.
In principle, yes, if you have the correct key or algorithm. However, with strong modern encryption (e.g., AES-256), decryption without the key is computationally infeasible.
Encryption is reversible (you can decrypt). Hashing is a one-way function that produces a fixed-size string from data; it cannot be reversed to reveal the original input, used for verification, not secrecy.
Yes, this is the standard passive construction. You can also say 'the encrypted data' using the past participle as an adjective.
