Expand description

HKDF key derivation (RFC 5869)

Implementations§

Source§

impl Hkdf

Source

pub fn derive_key( input_key_material: &[u8], salt: &[u8], info: &[u8], output_length: usize, ) -> DerivedKey

Extract-and-Expand key derivation using HMAC-SHA256

§Arguments
  • input_key_material - Input keying material
  • salt - Optional salt (use empty slice if none)
  • info - Optional context/application info
  • output_length - Desired output length in bytes
Source

pub fn derive_multiple_keys( input_key_material: &[u8], salt: &[u8], contexts: &[&[u8]], key_length: usize, ) -> Vec<DerivedKey>

Derive multiple keys from a single input
