我有例如

EXPKEY : 010001
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

什么是用于检索 PEM 编码公钥的 openssl 或任何 linux 命令

谢谢

据我所知，没有任何openssl应用程序或 Linux 命令支持您正在寻找的内容。一种选择是利用 python加密模块。安装pip install cryptography并使用以下内容：

import sys
from cryptography.hazmat.primitives.asymmetric.rsa import RSAPublicNumbers
from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.backends.openssl import backend

pubnums = RSAPublicNumbers(
    int(sys.argv[2], 16),
    int(sys.argv[1], 16)
)
pubkey = pubnums.public_key(backend)
pubkey_PEM = pubkey.public_bytes(
    encoding = serialization.Encoding.PEM,
    format = serialization.PublicFormat.PKCS1).decode('utf-8')
print(pubkey_PEM) # Remove the parenthesis for old versions of python

使用您的输入测试脚本，假设它被称为makePubPEM.py：

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
