Struct Rar5Crypto 

pub struct Rar5Crypto { /* private fields */ }

Available on crate feature crypto only.

RAR5 cryptographic operations.

Implementations

impl Rar5Crypto

pub fn derive_key(password: &str, salt: &[u8; 16], lg2_count: u8) -> Self

Derive key from password using PBKDF2-HMAC-SHA256.

RAR5 derives these values using PBKDF2-HMAC-SHA256:

1. Key (32 bytes) - for AES-256 encryption (at iterations)
2. Password check (32 bytes) - for password verification (at iterations + 32)

Note: RAR5 spec also defines a hash key (at iterations + 16) for MAC checksums, but this implementation does not compute it since we don’t verify header MACs.

pub fn verify_password(&self, expected: &[u8; 8]) -> bool

Verify password using the stored check value.

pub fn decrypt(&self, iv: &[u8; 16], data: &mut [u8]) -> Result<(), CryptoError>

Decrypt data in-place using AES-256-CBC.

pub fn decrypt_to_vec( &self, iv: &[u8; 16], data: &[u8], ) -> Result<Vec<u8>, CryptoError>

Decrypt data to a new buffer.
