X509EncodedKeySpec

open class X509EncodedKeySpec : EncodedKeySpec

kotlin.Any
↳	java.security.spec.EncodedKeySpec
	↳	java.security.spec.X509EncodedKeySpec

This class represents the ASN.1 encoding of a public key, encoded according to the ASN.1 type SubjectPublicKeyInfo. The SubjectPublicKeyInfo syntax is defined in the X.509 standard as follows:

SubjectPublicKeyInfo ::= SEQUENCE {
    algorithm AlgorithmIdentifier,
    subjectPublicKey BIT STRING }

Summary

Public constructors
`X509EncodedKeySpec(encodedKey: ByteArray!)` Creates a new `X509EncodedKeySpec` with the given encoded key.
`X509EncodedKeySpec(encodedKey: ByteArray!, algorithm: String!)` Creates a new `X509EncodedKeySpec` with the given encoded key.

Public methods
open ByteArray!	`getEncoded()` Returns the key bytes, encoded according to the X.
String!	`getFormat()` Returns the name of the encoding format associated with this key specification.

Inherited functions

From class EncodedKeySpec

String!

getAlgorithm()

Returns the name of the algorithm of the encoded key.

X509EncodedKeySpec

Added in API level 1

X509EncodedKeySpec(encodedKey: ByteArray!)

Creates a new X509EncodedKeySpec with the given encoded key.

Parameters
`encodedKey`	ByteArray!: the key, which is assumed to be encoded according to the X.509 standard. The contents of the array are copied to protect against subsequent modification.

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

X509EncodedKeySpec

Added in API level 35

X509EncodedKeySpec(
    encodedKey: ByteArray!, 
    algorithm: String!)

Creates a new X509EncodedKeySpec with the given encoded key. This constructor is useful when subsequent callers of the X509EncodedKeySpec object might not know the algorithm of the key.

Parameters
`encodedKey`	ByteArray!: the key, which is assumed to be encoded according to the X.509 standard. The contents of the array are copied to protect against subsequent modification.
`algorithm`	String!: the algorithm name of the encoded public 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

getEncoded

Added in API level 1

open fun getEncoded(): ByteArray!

Returns the key bytes, encoded according to the X.509 standard.

Return
`ByteArray!`	the X.509 encoding of the key. Returns a new array each time this method is called.

getFormat

Added in API level 1

fun getFormat(): String!

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

Return
`String!`	the string `"X.509"`.
