Parameters

This function has one parameter:

data – The data to be hashed.

Description

This function calculates the SHA-256 hash of a binary or text data item. SHA-256 produces a 256-bit (32-byte) hash value. A SHA-256 hash value is typically rendered as a hexadecimal number, 64 digits long. Here’s an example showing how the SHA-256 hash of a file can be calculated:

sha256(fileload("~/Library/Application Support/AddressBook/AddressBook-v22.abcddb"))
