Say it like this
- We need to implement hashing for password storage.
- The hashing algorithm ensures data integrity.
- Use strong hashing to protect sensitive information.
Use it at work
Security
- We store passwords using hashing with bcrypt.
- Never store passwords in plain text. Hash them.
Code review
- Use SHA-256 for hashing the file, not MD5.
- Hashing can't be reversed. That's the point.
Data
- We use hashing to create a stable ID for each user.
- Consistent hashing helps us spread data across nodes.
Don't say this
Hashing is not encryption; it is a one-way process, not encryption which is reversible.

More about hashing
Real examples(3)
- in a standup
"Yesterday we finished implementing hashing for all user credentials using SHA-256."
- in a code review
"This pull request adds hashing to the payment data before it gets logged to ensure compliance."
- in a team meeting
"We should discuss upgrading our hashing algorithm because MD5 is no longer considered secure."
More mistakes(2)
Handle with care. Hashing is not the same as encryption. Hashing is one-way and irreversible, while encryption is two-way and reversible.
- ✕The hashing will let us decrypt the original data.✓The hashing will let's verify the data has not been tampered with.
Hashing cannot be reversed or decrypted; it only creates a fingerprint for verification.
- ✕We are using hashing to send secure messages.✓We're using encryption to send secure messages.
Hashing verifies integrity; encryption protects confidentiality and is reversible.
Other forms(3)
- hashing noun
"Hashing is essential for securing passwords in modern applications."
- hash noun

Questions(5)
- What does hashing mean in software engineering?
- Hashing is the process of converting data of any size into a fixed-size string using a mathematical algorithm. It is a one-way process, meaning you cannot reverse it to get the original data back. Hashing is widely used to secure passwords, verify file integrity, and detect data tampering.
- How do you use hashing in a sentence at work?
- You can say: 'We are implementing hashing for all user passwords,' or 'This algorithm uses SHA-256 hashing for security,' or 'We should hash the transaction data before logging it.' The noun is 'hashing' and the verb is 'hash.'
- Is hashing formal or informal?
- Hashing is neutral and technical. It is used in both formal documentation (design specifications, security policies) and informal conversations (team meetings, code reviews). It is not slang; it is standard technical vocabulary in software engineering.
- What is the difference between hashing and encryption?
- Hashing is one-way and irreversible; once data is hashed, you cannot get the original data back. Encryption is two-way and reversible; encrypted data can be decrypted back to its original form. Hashing is used for verification and security storage; encryption is used for protecting data in transit or at rest when you need to access it later.
- What are common hashing algorithms?
- Common hashing algorithms include MD5 (now considered weak), SHA-1 (deprecated for security), SHA-256 (widely used and secure), SHA-512, and bcrypt (specialized for password hashing). The choice depends on your use case and security requirements.
