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

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".
