Python和Golang之间的RSA加密/解密不起作用？

pem格式的私钥有多行，也许您可以尝试从文件中读取私钥

PRIVATE_KEY = open('./private.pem', 'r').read()

下面的代码在我的测试服务器上工作

加密

package main

import (
    "crypto/rand"
    "crypto/rsa"
    "crypto/sha256"
    "crypto/x509"
    "encoding/base64"
    "encoding/pem"
    "fmt"
    "log"
    "os"
)

func main() {
    s := "heloo"
    publicKey, _ := os.ReadFile("./rsa_public_key.pem")
    block, _ := pem.Decode([]byte(publicKey))
    if block.Type != "PUBLIC KEY" {
        log.Fatal("error decoding public key from pem")
    }
    parsedKey, err := x509.ParsePKIXPublicKey(block.Bytes)
    if err != nil {
        log.Fatal("error parsing key")
    }
    var ok bool
    var pubkey *rsa.PublicKey
    if pubkey, ok = parsedKey.(*rsa.PublicKey); !ok {
        log.Fatal("unable to parse public key")
    }
    rng := rand.Reader
    ciphertext, err := rsa.EncryptOAEP(sha256.New(), rng, pubkey, []byte(s), nil)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(base64.StdEncoding.EncodeToString(ciphertext))
}

用于生成RSA密钥的命令

openssl genrsa -out rsa_private_key.pem 1024
openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
