H A Dasymmetric-keys.rst4 Asymmetric / Public-key Cryptography Key Type
10 - Key identification.
13 - Asymmetric key subtypes.
21 The "asymmetric" key type is designed to be a container for the keys used in
22 public-key cryptography, without imposing any particular restrictions on the
23 form or mechanism of the cryptography or form of the key.
25 The asymmetric key is given a subtype that defines what sort of data is
26 associated with the key and provides operations to describe and destroy it.
27 However, no requirement is made that the key data actually be stored in the
28 key.
