PKCS8EncodedKeySpec

open class PKCS8EncodedKeySpec : EncodedKeySpec
kotlin.Any
   ↳ java.security.spec.EncodedKeySpec
   ↳ java.security.spec.PKCS8EncodedKeySpec

This class represents the ASN.1 encoding of a private key, encoded according to the ASN.1 type PrivateKeyInfo. The PrivateKeyInfo syntax is defined in the PKCS#8 standard as follows: 

PrivateKeyInfo ::= SEQUENCE {
    version Version,
    privateKeyAlgorithm PrivateKeyAlgorithmIdentifier,
    privateKey PrivateKey,
    attributes [0] IMPLICIT Attributes OPTIONAL }
 
  Version ::= INTEGER
 
  PrivateKeyAlgorithmIdentifier ::= AlgorithmIdentifier
 
  PrivateKey ::= OCTET STRING
 
  Attributes ::= SET OF Attribute

Public constructors

PKCS8EncodedKeySpec

Added in API level 1
PKCS8EncodedKeySpec(encodedKey: ByteArray!)

Creates a new PKCS8EncodedKeySpec with the given encoded key.

Parameters
encodedKey ByteArray!: the key, which is assumed to be encoded according to the PKCS #8 standard. The contents of the array are copied to protect against subsequent modification.
Exceptions
java.lang.NullPointerException if encodedKey is null.

PKCS8EncodedKeySpec

Added in API level 35
PKCS8EncodedKeySpec(
    encodedKey: ByteArray!, 
    algorithm: String!)

Creates a new PKCS8EncodedKeySpec with the given encoded key and algorithm. This constructor is useful when subsequent callers of the PKCS8EncodedKeySpec object might not know the algorithm of the private key.

Parameters
encodedKey ByteArray!: the key, which is assumed to be encoded according to the PKCS #8 standard. The contents of the array are copied to protect against subsequent modification.
algorithm String!: the algorithm name of the encoded private 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 PKCS #8 standard.

Return
ByteArray! the PKCS #8 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 "PKCS#8".
