    • createSHA1KeyIdentifier

      public static SubjectKeyIdentifier createSHA1KeyIdentifier​(SubjectPublicKeyInfo keyInfo)
      Deprecated.
      use org.bouncycastle.cert.X509ExtensionUtils.createSubjectKeyIdentifier
      Return a RFC 3280 type 1 key identifier. As in: 
       (1) The keyIdentifier is composed of the 160-bit SHA-1 hash of the
 value of the BIT STRING subjectPublicKey (excluding the tag,
 length, and number of unused bits).
      Parameters:
      keyInfo - the key info object containing the subjectPublicKey field.
      Returns:
      the key identifier.

    • createTruncatedSHA1KeyIdentifier

      public static SubjectKeyIdentifier createTruncatedSHA1KeyIdentifier​(SubjectPublicKeyInfo keyInfo)
      Deprecated.
      use org.bouncycastle.cert.X509ExtensionUtils.createTruncatedSubjectKeyIdentifier
      Return a RFC 3280 type 2 key identifier. As in: 
       (2) The keyIdentifier is composed of a four bit type field with
 the value 0100 followed by the least significant 60 bits of the
 SHA-1 hash of the value of the BIT STRING subjectPublicKey.
      Parameters:
      keyInfo - the key info object containing the subjectPublicKey field.
      Returns:
      the key identifier.
