Securely search encrypted database fields

Securely search encrypted database fields. Contribute to ankane/blind_index development by creating an account on GitHub.We use this approach by Scott Arciszewski. To summarize, we compute a keyed hash of the sensitive data and store it in a column. To query, we apply the keyed hash function to the value we’re searching and then perform a database search. This results in performant queries for exact matches. LIKE queries are not possible, but you can index expressions.
