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.
RSA

RSA public key.

Fields of RSA

e: MPI

Public exponent

n: MPI

Public modulo N = pq.

Fields of Unknown

mpis: Box<[MPI]>

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.
