Examples of sun.security.krb5.EncryptionKey

sun.security.krb5.Asn1Exception
This class encapsulates the concept of an EncryptionKey. An encryption key is defined in RFC 4120 as: EncryptionKey ::= SEQUENCE { keytype [0] Int32 -- actually encryption type --, keyvalue [1] OCTET STRING } keytype This field specifies the encryption type of the encryption key that follows in the keyvalue field. Although its name is "keytype", it actually specifies an encryption type. Previously, multiple cryptosystems that performed encryption differently but were capable of using keys with the same characteristics were permitted to share an assigned number to designate the type of key; this usage is now deprecated. keyvalue This field contains the key itself, encoded as an octet string.
