DER 格式的公鑰容器的技術名稱是什麼？

我有以下格式的公鑰（格式中性；類型由 DER 字節指定）格式：

$ cat pubkey.der | openssl asn1parse -inform der -i
   0:d=0  hl=4 l= 290 cons: SEQUENCE
   4:d=1  hl=2 l=  13 cons:  SEQUENCE
   6:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
  17:d=2  hl=2 l=   0 prim:   NULL
  19:d=1  hl=4 l= 271 prim:  BIT STRING

$ cat pubkey.der | openssl rsa -inform der -pubin -text

這種格式的技術名稱是什麼？我一直想稱它為PKCS#8，但我認為這是不正確的，因為 PKCS#8 是一種私鑰格式。我們將公鑰的 PKCS#8 等效 DER 格式命名為什麼？

從RFC 5280 (X.509)可以看出，這種結構是SubjectPublicKeyInfo. 該欄位的格式如下：

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

AlgorithmIdentifier定義如下：

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

上述兩種類型定義了ASN.1中外層容器的格式（與欄位NULL對應的值parameters）。是由PKCS #1 v2.1 的附錄 A.1.1定義的BIT STRING內部對象，如下所示：

RSAPublicKey ::= SEQUENCE {
   modulus           INTEGER,  -- n
   publicExponent    INTEGER   -- e
}
