public interface Key
This is the key algorithm for that key. The key algorithm is usually an encryption or asymmetric operation algorithm (such as DSA or RSA), which will work with those algorithms and with related algorithms (such as MD5 with RSA, SHA-1 with RSA, Raw DSA, etc.)
This is an external encoded form for the key used when a standard
representation of the key is needed outside the Java Virtual Machine,
as when transmitting the key to some other party. The key
is encoded according to a standard format (such as
X.509 SubjectPublicKeyInfo
).
Note: The syntax of the ASN.1 type SubjectPublicKeyInfo
is defined as follows:
SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, subjectPublicKey BIT STRING } AlgorithmIdentifier ::= SEQUENCE { algorithm OBJECT IDENTIFIER, parameters ANY DEFINED BY algorithm OPTIONAL }For more information, see RFC 2459: Internet X.509 Public Key Infrastructure Certificate and CRL Profile.
This is the name of the format of the encoded key.
Modifier and Type | Method and Description |
---|---|
java.lang.String |
getAlgorithm()
Returns the standard algorithm name for this key.
|
byte[] |
getEncoded()
Returns the key in its primary encoding format, or null
if this key does not support encoding.
|
java.lang.String |
getFormat()
Returns the name of the primary encoding format of this key, or null
if this key does not support encoding.

java.lang.String getAlgorithm()
java.lang.String getFormat()
"X.509"
.
Similarly, the name of the ASN.1 data format for private keys is
PrivateKeyInfo, as defined by the PKCS #8 standard; in this case,
the returned format is "PKCS#8"
