abstract class EncodedKeySpec : KeySpec

kotlin.Any
↳	java.security.spec.EncodedKeySpec

Known Direct Subclasses

PKCS8EncodedKeySpec, X509EncodedKeySpec, XdhKeySpec

PKCS8EncodedKeySpec	This class represents the ASN.
X509EncodedKeySpec	This class represents the ASN.
XdhKeySpec	External Diffie–Hellman (XDH) key spec holding either a public or private key.

This class represents a public or private key in encoded format.

Summary

Public constructors
`EncodedKeySpec(encodedKey: ByteArray!)` Creates a new `EncodedKeySpec` with the given encoded key.

Protected constructors
`EncodedKeySpec(encodedKey: ByteArray!, algorithm: String!)` Creates a new `EncodedKeySpec` with the given encoded key.

Public methods
open String!	`getAlgorithm()` Returns the name of the algorithm of the encoded key.
open ByteArray!	`getEncoded()` Returns the encoded key.
abstract String!	`getFormat()` Returns the name of the encoding format associated with this key specification.

Public constructors

EncodedKeySpec

Added in API level 1

EncodedKeySpec(encodedKey: ByteArray!)

Creates a new EncodedKeySpec with the given encoded key.

Parameters
`encodedKey`	ByteArray!: the encoded key. The contents of the array are copied to protect against subsequent modification.

Exceptions
`java.lang.NullPointerException`	if `encodedKey` is null.

Protected constructors

EncodedKeySpec

Added in API level 35

protected EncodedKeySpec(
    encodedKey: ByteArray!, 
    algorithm: String!)

Creates a new EncodedKeySpec with the given encoded key. This constructor is useful when subsequent callers of the EncodedKeySpec object might not know the algorithm of the key.

Parameters
`encodedKey`	ByteArray!: the encoded key. The contents of the array are copied to protect against subsequent modification.
`algorithm`	String!: the algorithm name of the encoded key See the KeyFactory section in the Java Security Standard Algorithm Names Specification for information about standard algorithm names.

Exceptions
`java.lang.NullPointerException`	if `encodedKey` or `algorithm` is null.
`java.lang.IllegalArgumentException`	if `algorithm` is the empty string `""`

Public methods

getAlgorithm

Added in API level 35

open fun getAlgorithm(): String!

Returns the name of the algorithm of the encoded key.

Return
`String!`	the name of the algorithm, or null if not specified

getEncoded

Added in API level 1

open fun getEncoded(): ByteArray!

Returns the encoded key.

Return
`ByteArray!`	the encoded key. Returns a new array each time this method is called.

getFormat

Added in API level 1

abstract fun getFormat(): String!

Returns the name of the encoding format associated with this key specification.

If the opaque representation of a key (see Key) can be transformed (see KeyFactory) into this key specification (or a subclass of it), getFormat called on the opaque key returns the same value as the getFormat method of this key specification.

Return
`String!`	a string representation of the encoding format.
