Here’s how the Python official documentation defines a dictionary:An associative array, where arbitrary keys are mapped to values. The keys can be any object with __hash__() and __eq__() methods. (Source)There are a couple of points to notice in this definition:...
There are differences in languages like Java and Python (for example, in Java, you can use the HashMap interface as a part of the Java collection package). Still, ultimately, most general-purpose languages have a few different ways to implement a hash table. Let's start with the simplest...
Use the pgcrypto extension in your databases when you need to hash or encrypt specific pieces of data to comply with regulations or similar needs. Hashing in pgcrypto Hashing is a method for generating cryptographically secure representation of data, usually with a fixed length that d...

to the HSM each time. For very large data sets (e.g., a database), it’s not practical to move gigabytes of data between the data set and the HSM for every read/write operation. Instead, envelope encryption allows a data encryption key to be distributed to the application when it’s...
