A secret key.

Provides a typed and structured way of storing multiple MPIs in Key packets. Secret key components are protected by storing them using ProtectedMPI.

Note: This enum cannot be exhaustively matched to allow future extensions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl SecretKeyMaterial

pub fn algo(&self) -> Option<PublicKeyAlgorithm>

Returns, if known, the public-key algorithm for this secret key.

impl SecretKeyMaterial
