Which calculated field mapping function should be used to convert an email to a SHA256 hash value?

The function that accurately converts an email to a SHA256 hash value is represented as sha256(email). This function follows a straightforward syntax indicative of many programming and data transformation languages, where the function name is explicitly named for clarity and simplicity. In this case, 'sha256' is the function being called, with 'email' as its input parameter.

Using this method effectively transforms the original email string into a secure SHA256 hash, which is essential for protecting user information while allowing for operations such as comparison or verification without exposing original data.

Other options may suggest similar functionality but either follow a different syntax or contain elements that are not standard within typical data transformation frameworks for hash conversion. Understanding the standard naming conventions and format for hash functions is crucial for accurately implementing data security practices.
