Options

hashFunctionName

• Type : string
• Default : sha384

The supported hash functions are SHA-256, SHA-384, and SHA-512.
This is in compliance with the W3C specification.

Conformant user agents must support the SHA-256, SHA-384 and SHA-512 cryptographic hash functions for use as part of a request’s integrity metadata and may support additional hash functions.

The default is selected based on the W3C specification.

At the time of writing, SHA-384 is a good baseline.
