Struct KeyingMaterialExporter 

pub struct KeyingMaterialExporter { /* private fields */ }

An object of this type can export keying material.

Implementations

impl KeyingMaterialExporter

pub fn derive<T: AsMut<[u8]>>( &self, label: &[u8], context: Option<&[u8]>, output: T, ) -> Result<T, Error>

Derives key material from the agreed connection secrets.

This function fills in output with output.len() bytes of key material derived from a master connection secret using label and context for diversification. Ownership of the buffer is taken by the function and returned via the Ok result to ensure no key material leaks if the function fails.

See RFC5705 for more details on what this does and is for. In other libraries this is often named SSL_export_keying_material() or SslExportKeyingMaterial().

This function is not meaningful if output.len() is zero and will return an error in that case.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
