golang x509.MarshalPKIXPublicKey 与 x509.MarshalPKCS1PublicKey()
golang x509.MarshalPKIXPublicKey vs x509.MarshalPKCS1PublicKey()
谁能帮我理解 MarshalPKIXPublicKey() 和 MarshalPKCS1PublicKey() 之间的区别？
根据评论：
// MarshalPKIXPublicKey 将 public 密钥序列化为 DER 编码的 PKIX 格式。
// MarshalPKCS1PublicKey 将 RSA public 密钥转换为 PKCS#1、ASN.1 DER 形式。
什么是 DER 编码的 PKIX 格式？
谢谢
你没有说清楚你不明白（或明白）多少。从基础开始：
ASN.1（抽象语法符号一）是一种通用方案，用于定义要在系统或程序之间通信或交换的数据结构。
DER（可分辨编码规则）是一种方案，用于将 ASN.1 数据编码为可以通信 and/or 存储的字节序列，并将这些字节序列解码回 ASN。 1 数据无损。
PKCS1 aka RFC 2313,2437,3447,8017 (Public Key Cryptography Standard #1) is a standard that defines a range of things about using the RSA algorithm, among which Appendix A 定义了一个名为 RSAPublicKey 的 ASN.1 结构来表示 RSA public密钥，它像任何 ASN.1 结构一样可以进行 DER 编码。
MarshalPKCS1PublicKey converts an RSA public key to PKCS#1, ASN.1 DER form.
明确表示 PKCS1 中 RSA public 密钥的 ASN.1 结构的 DER 编码。
PKIX (Public Key Infrastructure X.509) is an Internet variant (formally, a profile) of the X.509 standard originally defined by then-CCITT now-ITU-T, currently in rfc5280. X.509, and PKIX, primarily defines a format for a public-key certificate which binds a public-key to an identity along with other metadata. To do this it has to contain a representation of a public-key that can handle multiple public-key algorithms, which is done using the SubjectPublicKeyInfo structure which, fairly simply, consists of an AlgorithmIdentifier that identifies the algorithm, plus a BIT STRING that contains the actual public-key value in an algorithm-dependent manner. The algorithm-dependent part for RSA is specified in rfc3279 sec 2.3.1 如您所见，它是 PKCS1 的 RSAPublicKey 结构，DER 编码。
因此 'DER-encoded PKIX format' 的 RSA public 密钥 表示 PKIX/X.509 SubjectPublicKeyInfo 结构的 DER 编码，其中包含 RSA 的算法标识符（OID 1.2.840.113549.1.1.1 和参数 NULL）和包含 DER 编码的 PKCS1 RSAPublicKey 的 BIT STRING。
