メソッドの詳細

• getAlgorithm

  public java.lang.String getAlgorithm​()

  定義:

  getAlgorithm インタフェース内 java.security.Key

• getFormat

  public java.lang.String getFormat​()

  定義:

  getFormat インタフェース内 java.security.Key

• getEncoded

  public byte[] getEncoded​()

  This follows the docs from java.security.spec.PKCS8EncodedKeySpec quote:

    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
  

    AlgorithmIdentifier ::= SEQUENCE
    {
      algorithm           OBJECT IDENTIFIER,
      parameters          ANY OPTIONAL
    }
  

  Ref: https://tools.ietf.org/html/draft-josefsson-pkix-eddsa-04 Note that the private key encoding is not fully specified in the Josefsson draft version 04, and the example could be wrong, as it's lacking Version and AlgorithmIdentifier. This will hopefully be clarified in the next draft. But sun.security.pkcs.PKCS8Key expects them so we must include them for keytool to work. This encodes the seed. It will return null if constructed from a spec which was directly constructed from H, in which case seed is null.
