Say it like this
- End-to-end encryption ensures that only the sender and receiver can read messages
- We need stronger encryption for the payment gateway
- The encryption key must be stored securely and never hardcoded
Use it at work
Security
- All data is encrypted at rest and in transit.
- We use AES-256 encryption for stored files.
With customers
- Is customer data encrypted?
- Yes, we encrypt everything with keys you control.
Code review
- This field has personal data. Can we add encryption?
- Don't roll your own encryption. Use the library.
Don't say this
Hashing and encryption are different. Hashing is one-way; encryption is reversible with a key.
Don't mix it up
| Term | What it is | Who writes or uses it | When |
|---|---|---|---|
| encryption | Locking data so only key holders read it | Security, developers | Sensitive data |
| hashing | One-way fingerprint, can't be reversed | Developers | Passwords |
| encoding | Format change, anyone can reverse | Developers | Data transfer |

Real examples(3)
- in a standup

- in a code review
"This API endpoint needs encryption enabled before we can merge the pull request."
- in a team meeting
"Our encryption strategy should follow industry best practices and pass security audits."
More mistakes(2)
Handle with care. Often confused with hashing or encoding. Encryption is reversible with a key; hashing is not. Do not say encrypt for all security processes.
- ✕The encryption is stored in the code for security.✓The encryption key is stored securely in an environment variable or vault.
Never hardcode encryption keys. Store them securely using key management systems.
- ✕We do not need encryption because our server is private.✓We should use encryption regardless of network privacy for defense in depth.
Encryption protects data at rest and in transit, providing multiple layers of security.
Other forms(3)
- encryption noun
"Encryption is required for all payment data."
- encrypt verb
"We encrypt user information before storing it in the database."
- encrypted adjective
"The encrypted message can only be read with the correct key."
Often used with(5)
- end-to-end encryption · Used when communication is encrypted from sender to recipient with no intermediary access
- encryption key · The secret code needed to decrypt encrypted data; must be kept secure
- encryption algorithm · The mathematical method used to encrypt data, such as AES or RSA
- enable encryption · To activate or turn on encryption functionality in a system or application
- encryption standard · Established security protocols like AES-256 or TLS used across industries
Similar words(2)
- encoding · Encoding converts data to another format but is not necessarily secure; encryption always provides security
- scrambling · Less formal term; encryption is the technical standard term in professional contexts

- unencrypted
Questions(5)
- What does encryption mean in software engineering?
- Encryption is the process of converting readable data into an unreadable format using a mathematical algorithm and a secret key. Only someone with the correct key can decrypt it back to readable form. In software engineering, it is used to protect sensitive information like passwords, payment data, and personal user information from unauthorized access or theft.
- How do you use encryption in a sentence at work?
- You can use it as a noun: 'We need encryption for the database.' Or as a verb: 'We must encrypt all payment information.' Common phrases include 'implement encryption,' 'enable encryption,' 'encryption standards,' and 'encryption key management.' Example: 'The security team requires AES-256 encryption before we can deploy this feature.'
- Is encryption formal or informal?
- Encryption is a formal, technical term used in professional software development contexts. It appears in security documentation, compliance requirements, code reviews, and team meetings. While it is not overly casual, it is standard terminology that all tech professionals use and expect.
- What is the difference between encryption and hashing?
- Encryption is reversible—with the correct key, you can decrypt data back to its original form. Hashing is one-way; you cannot reverse a hash to get the original data. Use encryption to protect data you need to read later (like stored files), and use hashing for passwords where you only need to verify them, not retrieve them.
- What are common encryption algorithms mentioned in tech?
- AES-256 and AES-128 are symmetric encryption standards. RSA and ECC are asymmetric algorithms. TLS is used for secure web communication. SHA-256 is often mentioned, but it is actually a hashing algorithm, not encryption. Your team will discuss these by name in security reviews and architectural meetings.
