从文件加载加密的PKCS1私钥

Question

I have a PKCS1 private key in a file and I load it using

b, err := ioutil.ReadFile(path)
if err != nil {
    return nil, err
}

Then, I try to convert it into private key object

block, _ := pem.Decode(b)
der, err := x509.DecryptPEMBlock(block, []byte("qwerty"))
if err != nil {
    return nil, err
}

bytes := pem.EncodeToMemory(&pem.Block{Type: "RSA PRIVATE KEY", Bytes: der})

return x509.ParsePKCS1PrivateKey(bytes)

But this code throws exception in DecryptPEMBlock

x509: no DEK-Info header in block

I didn't find any documentation about this in golang

Answer 1

Go does not have package to decode PKCS files it seems

Checkout this link for more details PKCS

I cant find a package to decode PKCS1 keys

Use this package to decode the PKCS8 files, there are some packages to decode PKCS8, PKCS10, PKCS12 but not for PKCS1
