Keypublic abstract interface Key
|Implements an abstract class that represents all keys (both
symmetric and asymmetric).|
Returns the name of the algorithm associated with this secret key.
Returns the key in its primary encoding format, or null
if this key does not support encoding.
Returns the name of the primary encoding format of this key, or null
if this key does not support encoding. The primary encoding format is
named in terms of the appropriate ASN.1 data format, if an ASN.1
specification for this key exists. For example, the name of the ASN.1
data format for public keys is SubjectPublicKeyInfo, as defined
the X.509 standard; in this case, the returned format is
Similarly, the name of the ASN.1 data format for private keys is
PrivateKeyInfo, as defined by the PKCS #8 standard; in this
the returned format is
