hashing
C1Technical/Formal for computing; Informal for discussion sense.
Definition
Meaning
The process of using a hash function to convert data (like a string or a file) into a fixed-size string of characters (a hash), typically for efficient data retrieval or security.
It can also refer to discussing or arguing about something thoroughly, especially in a repetitive or prolonged manner (from the phrase 'hash something out' or 'hash over').

Frequently Asked Questions
No. Encryption is a two-way process (encrypt/decrypt). Hashing is typically a one-way process; you cannot feasibly retrieve the original input from the hash.
Yes, informally. 'Hashing things out' means discussing something thoroughly to resolve it or reach an agreement.
A hash collision occurs when two different inputs produce the same hash output. A good hashing algorithm minimizes this probability.
No, it's pronounced the same (/ˈhæʃɪŋ/) regardless of context.
