[−][src]Struct elliptic_curve::secret_key::SecretKey
This is supported on crate feature
zeroize
only.Elliptic curve secret keys.
This type wraps a secret scalar value, helping to prevent accidental
exposure and securely erasing the value from memory when dropped
(when the zeroize
feature of this crate is enabled).
