Private key data: digital signature key pairs.

SSH private keys contain pairs of public and private keys for various supported digital signature algorithms.

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.
