Struct WrapKeyFromPassphrase 

Source 
pub struct WrapKeyFromPassphrase<'passphrase> {
    passphrase: &'passphrase Passphrase,
    kind: WrapKeyKind,
}
Expand description

A helper struct for the creation of a WrapKey from a Passphrase.

The struct tracks a Passphrase and a WrapKeyKind.

The passphrase is guaranteed to be validated against the passphrase policy imposed by WrapKey.

Fields§

§passphrase: &'passphrase Passphrase§kind: WrapKeyKind

Implementations§

Source§

impl<'passphrase> WrapKeyFromPassphrase<'passphrase>

Source

pub(crate) const ARGON2_SALT: &'static [u8] = b"Salt for a Signstar backup key"

The static salt used for argon2, when hashing a passphrase.

Source

pub fn new( passphrase: &'passphrase Passphrase, kind: WrapKeyKind, ) -> Result<Self, Error>

Creates a new WrapKeyFromPassphrase.

§Note

It is recommended to use WrapKeyKind::Aes256 for kind, as it is considered resistant against quantum attacks.

§Errors

Returns an error, if checking passphrase against WrapKey::PASSPHRASE_POLICY fails.

impl<'passphrase> TryFrom<WrapKeyFromPassphrase<'passphrase>> for WrapKey

Source§

fn try_from( value: WrapKeyFromPassphrase<'passphrase>, ) -> Result<Self, Self::Error>

Creates a new WrapKey from a WrapKeyFromPassphrase.

§Errors

Returns an error, if hashing the passphrase of value into the targeted data of a WrapKey fails.

Source§

type Error = Error
