Struct Pbkdf2 

pub struct Pbkdf2<H: HashFunction + Clone, const S: usize = 16> { /* private fields */ }

PBKDF2 implementation using any HMAC-based PRF

PBKDF2 can be used with any pseudorandom function, but this implementation uses HMAC with a configurable hash function.

Implementations

impl<H: HashFunction + Clone, const S: usize> Pbkdf2<H, S>

pub fn pbkdf2( password: &[u8], salt: &[u8], iterations: u32, key_length: usize, ) -> Result<Zeroizing<Vec<u8>>>

Internal PBKDF2 implementation with secure key handling

This implements the core PBKDF2 algorithm as defined in RFC 8018 Section 5.2 with enhanced security for key material handling.

Arguments

• password - The password to derive the key from
• salt - The salt value
• iterations - The number of iterations
• key_length - The length of the derived key in bytes

Returns

The derived key of length key_length bytes

pub fn pbkdf2_secure( password: &[u8], salt: &[u8], iterations: u32, key_length: usize, ) -> Result<Vec<u8>>

Secure PBKDF2 implementation that returns regular Vec
