Struct PrivateKey 

pub struct PrivateKey<P>
where
    P: Profile,
{ /* private fields */ }

A one-time WOTS private key bound to cryptographic profile P.

Signing APIs consume this value to make accidental key reuse harder. Raw bytes can still be copied deliberately, so the surrounding key-management system must enforce one-time use durably. This type does not zeroize on drop; see PrivateSeed for the corresponding memory-handling caveat.

Implementations

impl<P> PrivateKey<P>

where P: Profile,

pub const fn new(bytes: [u8; 32]) -> PrivateKey<P>

Creates a profile-bound private key from exact upstream-format bytes.

pub fn from_slice(bytes: &[u8]) -> Result<PrivateKey<P>, LengthError>

Parses a private key, rejecting every non-32-byte input.

Errors

Returns LengthError unless bytes contains exactly 32 bytes.

pub const fn expose_secret(&self) -> &[u8; 32]

Explicitly borrows the secret bytes for a cryptographic operation.

pub const fn into_secret(self) -> [u8; 32]

Explicitly returns the secret bytes.

Trait Implementations

impl<P> Debug for PrivateKey<P>

where P: Profile,

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

Formats the value using the given formatter.
