Expand description

A public key.

Provides a typed and structured way of storing multiple MPIs (and the occasional elliptic curve) in Key packets.

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

Variants (Non-exhaustive)

This enum is marked as 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

Returns the length of the public key in bits.

For finite field crypto this returns the size of the field we operate in, for ECC it returns Curve::bits().

Note: This information is useless and should not be used to gauge the security of a particular key. This function exists only because some legacy PGP application like HKP need it.

Returns None for unknown keys and curves.

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

Parses a set of OpenPGP MPIs representing a public key.

See Section 3.2 of RFC 4880 for details.
