Struct SecretKey 

pub struct SecretKey(/* private fields */);

Opaque, zeroized 256-bit key material.

Implementations

impl SecretKey

pub fn new(bytes: [u8; 32]) -> Self

Copies a 256-bit key into zeroized storage.

pub fn generate() -> Result<Self, CryptError>

Draws fresh 256-bit key material from the operating system’s cryptographic random source.

Errors

Returns CryptError::RandomnessUnavailable when the OS entropy source cannot be read. Callers must fail rather than fall back: a predictable data key is indistinguishable from no encryption.

pub fn from_slice(bytes: &[u8]) -> Result<Self, CryptError>

Copies a byte slice into zeroized storage.

Errors

Returns CryptError::InvalidKeyLength unless bytes is 32 bytes.
